April 1 in History

The Roman emperor was the ruler of the Roman Empire, starting with the granting of the title augustus to Octavian in 27 BC. The title of imperator, originally a military honorific, was usually used alongside caesar, originally a cognomen. When a given Roman is described as becoming emperor in English, it generally reflects his accession as augustus, and later as basileus. Early emperors also used the title princeps alongside other Republican titles, notably consul and pontifex maximus.

The foundation of Constantinople in 330 AD marks the conventional start of the Byzantine Empire, which fell to the Ottoman Empire in 1453 AD. Only the emperors who were recognized as legitimate rulers and exercised sovereign authority are included, to the exclusion of junior co-emperors who never attained the status of sole or senior ruler, as well as of the various usurpers or rebels who claimed the imperial title.

Alexios I Komnenos (Greek: Ἀλέξιος Κομνηνός, romanized: Aléxios Komnēnós, c. 1057 – 15 August 1118), Latinized as Alexius I Comnenus, was Byzantine emperor from 1081 to 1118. After usurping the imperial office he was faced with a collapsing empire and constant warfare throughout his reign. Alexios was able to curb the Byzantine decline and begin the military, financial, and territorial recovery known as the Komnenian restoration. His appeals to Western Europe for help against the Seljuk Turks were the catalyst that sparked the First Crusade. Although he was not the first emperor of the Komnenian dynasty, it was during his reign that the Komnenos family came to full power and initiated a hereditary succession to the throne. The son of John Komnenos and a nephew of Isaac I Komnenos, Alexios served with distinction under three Byzantine emperors. In 1081, he led a rebellion against Emperor Nikephoros III Botaneiates and took the throne for himself. He immediately faced an invasion of the western Balkans by the Normans under Robert Guiscard and his son Bohemond. Despite initial defeats, Alexios secured an alliance with Holy Roman Emperor Henry IV and drove back the Normans, recovering most of Byzantine losses by 1085. In 1091, he achieved a decisive victory over the Pechenegs at the Battle of Levounion in Thrace with the help of Cuman allies. Later in the 1090s, Alexios directed his attention towards Asia Minor, most of which had fallen to the Seljuk Turks. Desiring western support, he took reconciliatory measures towards the Papacy, and in 1095 his envoys made a formal appeal to Pope Urban II at the Council of Piacenza. At the subsequent Council of Clermont, Pope Urban formally called the First Crusade, which began a year after and concluded with much of western Anatolia restored to Byzantine rule. On Alexios's death in 1118, he was succeeded by his son John II Komnenos. Alexios's reign and campaigns were recorded by his daughter Anna Komnene in her Alexiad, a political and military history, which she named after her father.

The Eighty Years' War or Dutch Revolt (c. 1566/1568–1648) was an armed conflict in the Habsburg Netherlands between disparate groups of rebels and the Spanish government. The causes of the war included the Reformation, centralisation, excessive taxation, and the rights and privileges of the Dutch nobility and cities. After the initial stages, Philip II of Spain, the sovereign of the Netherlands, deployed his armies and regained control over most of the rebel-held territories. However, widespread mutinies in the Spanish army caused a general uprising. Under the leadership of the exiled William the Silent, the Catholic and Protestant-dominated provinces sought to establish religious peace while jointly opposing the king's regime with the Pacification of Ghent, but the general rebellion failed to sustain itself. Despite steady military and diplomatic successes by the Governor of Spanish Netherlands and General for Spain, the Duke of Parma, the Union of Utrecht continued their resistance, proclaiming their independence through the 1581 Act of Abjuration and establishing the Calvinist-dominated Dutch Republic in 1588. In the Ten Years thereafter, the Republic (whose heartland was no longer threatened) made conquests in the north and east and received diplomatic recognition from France and England in 1596. The Dutch colonial empire emerged, which began with Dutch attacks on Portugal's overseas territories. Facing a stalemate, the two sides agreed to a Twelve Years' Truce in 1609; when it expired in 1621, fighting resumed as part of the broader Thirty Years' War. An end was reached in 1648 with the Peace of Münster when Spain retained the Southern Netherlands and recognised the Dutch Republic as an independent country.

Johann Sebastian Bach was a German composer and musician of the late Baroque period. He is known for his prolific output across a variety of instruments and forms, including the orchestral Brandenburg Concertos; solo instrumental works such as the Cello Suites and Sonatas and Partitas for Solo Violin; keyboard works such as the Goldberg Variations and The Well-Tempered Clavier; organ works such as the Schübler Chorales and the Toccata and Fugue in D minor; and choral works such as the St. Matthew Passion and the Mass in B minor. He is known for his mastery of counterpoint, as heard in The Musical Offering and The Art of Fugue. Felix Mendelssohn precipitated the Bach Revival with a performance of the St. Matthew Passion in 1829. Ever since, Bach has been acclaimed as one of the greatest composers in the history of Western music.

The United States House of Representatives is a chamber of the bicameral United States Congress; it is the lower house, with the United States Senate being the upper house. Together, the House and Senate have the authority under Article One of the Constitution of the United States in enumerated matters to pass or defeat federal legislation, known as bills. Those that are also passed by the Senate are sent to the president for signature or veto. The House's exclusive powers include initiating all revenue bills, impeaching federal officers, and electing the president if no candidate receives a majority of votes in the Electoral College.

The American Civil War (April 12, 1861 – May 26, 1865; also known by other names) was a civil war in the United States between the Union ("the North") and the Confederacy ("the South"), which was formed in 1861 by Southern states that had seceded from the Union to preserve slavery in the United States. The South saw slavery as threatened because of the election of Abraham Lincoln as president in 1860 and the growing abolitionist movement in the North. The war ended with a Union victory, dissolution of the Confederacy and the national abolition of slavery, freeing four million African Americans. Decades of controversy over slavery came to a head when Lincoln, a Republican who opposed slavery's expansion, won the 1860 presidential election. Seven slave states in the South responded to Lincoln's victory by seceding from the United States and forming the Confederate States. The Confederate States seized United States forts and other federal assets in the South. The war began on April 12, 1861, when the Confederate States bombarded Fort Sumter in South Carolina. A wave of enthusiasm for war swept over the North and South, as military recruitment soared. Four more Southern states seceded after the war began and, led by its president Jefferson Davis, the Confederacy comprised eleven states, containing a third of the US population. Four years of intense combat, mostly in the South, ensued. During 1861–1862 in the western theater, the Union made permanent gains, though in the eastern theater the conflict was inconclusive. The abolition of slavery became a Union war goal on January 1, 1863, when Lincoln issued the Emancipation Proclamation, which declared all slaves in rebel states to be free, applying to more than 3.5 million of the 4 million enslaved people in the country. To the west, the Union first destroyed the Confederate river navy by the summer of 1862, then much of its western armies, and seized New Orleans. The successful 1863 Union siege of Vicksburg split the Confederacy in two at the Mississippi River, while Confederate general Robert E. Lee's incursion north failed at the Battle of Gettysburg. Union general Ulysses S. Grant's western successes led Lincoln to promote him to command of all Union armies in 1864. Inflicting an ever-tightening naval Union blockade of Confederate ports, the Union army marshaled resources and the manpower to attack the Confederate States army from all directions. That led to the fall of Atlanta in 1864 to Union general William Tecumseh Sherman, followed by his March to the Sea, which culminated in his taking Savannah. The last significant battles raged around the ten-month siege of Petersburg, gateway to the Confederate capital of Richmond. The Confederates abandoned Richmond, and on April 9, 1865, Lee surrendered to Grant following the Battle of Appomattox Court House, setting in motion the end of the war. Lincoln lived to see this victory but was shot by an assassin on April 14, dying the next day. By the end of the war, much of the South's infrastructure had been destroyed. The Confederacy collapsed, the Thirteenth Amendment abolished slavery (except as punishment for a crime) and four million enslaved black people were freed. The war-torn nation then entered the Reconstruction era in an attempt to rebuild the country, reunite by bringing the former Confederate states back into the United States, and grant civil rights to freed black slaves. The war is one of the most extensively studied and written about episodes in the history of the United States, and it remains the subject of cultural and historiographical debate. Interest continues in the myth of the Lost Cause of the Confederacy. The war was among the first to use industrial warfare. Railroads, the electrical telegraph, steamships, the ironclad warship, and mass-produced weapons were widely used. The war left an estimated 700,000 soldiers dead, along with an undetermined number of civilian deaths, making it the deadliest in U.S. history. The technology and brutality of the Civil War foreshadowed the coming world wars.

Singapore, officially the Republic of Singapore, is an island country in Southeast Asia. Its territory comprises a main island, over 60 satellite islands and islets, and one outlying islet. The country is about one degree of latitude north of the equator, off the southern tip of the Malay Peninsula, bordering the Strait of Malacca to the west, the Singapore Strait to the south along with the Riau Islands in Indonesia, the South China Sea to the east and the Straits of Johor along with the State of Johor in Malaysia to the north.

The Oceanic Steam Navigation Company, better known as the White Star Line, was a British shipping line. Founded out of the remains of a defunct packet company, it gradually grew to become one of the most prominent shipping companies in the world, providing passenger and cargo services between the British Empire and the United States. While many other shipping lines focused primarily on speed, White Star branded their services by focusing more on providing comfortable passages for both upper class travellers and steerage passengers.

Prince George of Greece and Denmark (Greek: Γεώργιος, romanized: Geórgios; 24 June 1869 – 25 November 1957) was the second son and child of George I of Greece and Olga Konstantinovna of Russia. He served as high commissioner of the Cretan State during its transition towards independence from Ottoman rule and union (Enosis) with Greece.

The Territorial Force was a part-time volunteer component of the British Army, created in 1908 to augment British land forces without resorting to conscription. The new organisation was created by the Territorial and Reserve Forces Act 1907 (7 Edw. 7. c. 9), which consolidated the 19th-century Volunteer Force and yeomanry into a unified auxiliary, commanded by the War Office and administered by local county territorial associations. The Territorial Force was designed to reinforce the regular army in expeditionary operations abroad, but because of political opposition it was assigned to home defence. Members were liable for service anywhere in the UK and could not be compelled to serve overseas unless they volunteered to do so. In the first two months of the First World War, territorials volunteered for foreign service in significant numbers, allowing territorial units to be deployed abroad. They saw their first action on the Western Front during the initial German offensive of 1914, and the force filled the gap between the near destruction of the regular army that year and the arrival of the New Army in 1915. Territorial units were deployed to Gallipoli in 1915 and, following the failure of that campaign, provided the bulk of the British contribution to allied forces in the Sinai and Palestine Campaign. By the war's end, the Territorial Force had fielded twenty-three infantry divisions and two mounted divisions on foreign soil. It was demobilised after the war and reconstituted in 1921 as the Territorial Army by the Territorial Army and Militia Act 1921 (11 & 12 Geo. 5. c. 37). The force experienced problems throughout its existence. On establishment, fewer than 40 per cent of the men in the previous auxiliary institutions transferred into it, and it was consistently under strength until the outbreak of the First World War. It was not considered to be an effective military force by the regular army and was denigrated by the proponents of conscription. Lord Kitchener chose to concentrate the Territorial Force on home defence and raise the New Army to reinforce the British Expeditionary Force (BEF) in France, a decision which disappointed the territorials. The need to replace the severe losses suffered by the BEF before the New Army was ready forced Kitchener to deploy territorial units overseas, compromising the force's ability to defend the homeland. To replace foreign-service units, the Territorial Force was doubled in size by creating a second line which mirrored the organisation of the original, first-line units. Second-line units assumed responsibility for home defence and provided replacement drafts to the first line. The second line competed with the New Army for limited resources and was poorly equipped and armed as a result. The provision of replacements to the first line compromised the second line's home defence capabilities until a third line was raised to take over responsibility for territorial recruitment and training. The second line's duties were further complicated by the expectation, later confirmed, that it too would be deployed overseas. Territorial units were initially deployed overseas to release regular units from non-combat duties. On the Western Front, individual battalions were attached to regular army formations and sent into action, and the territorials were credited with playing a key role in stopping the German offensive in late 1914. The first complete territorial division to be deployed to a combat zone arrived in France in March 1915. Territorial divisions began participating in offensive operations on the Western Front from June 1915 and at Gallipoli later that year. Because of the way it was constituted and recruited, the Territorial Force possessed an identity that was distinct from the regular army and the New Army. This became diluted as casualties were replaced with conscripted recruits following the introduction of compulsory service in early 1916. The Territorial Force was further eroded as a separate institution when county territorial associations were relieved of most of their administrative responsibilities. By the war's end, there was little to distinguish between regular, territorial and New Army formations.

The Royal Air Force (RAF) is the air and space force of the United Kingdom, British Overseas Territories and Crown Dependencies. It was formed towards the end of the First World War on 1 April 1918 through the merger of the Royal Flying Corps (RFC) and the Royal Naval Air Service (RNAS). Following the Allied victory over the Central Powers in 1918, they emerged as the largest air force in the world. Since its formation, they have played a significant role in British military history. In particular, during the Second World War, they defeated the German Luftwaffe's efforts to establish air superiority over Great Britain during the Battle of Britain, and played a key role in the Combined Bomber Offensive alongside the USAAF. The RAF's mission is to support the objectives of the British Ministry of Defence (MOD), which are to "provide the capabilities needed to ensure the security and defence of the United Kingdom and overseas territories, including against terrorism; to support the Government's foreign policy objectives particularly in promoting international peace and security". Its mission statement as "... [to provide] an agile, adaptable and capable Air Force that, person for person, is second to none, and that makes a decisive air power contribution in support of the UK Defence Mission". The mission statement is supported by the RAF's definition of air power, which guides its strategy. Air power is defined as "the ability to project power from the air and space to influence the behaviour of people or the course of events". Today, the Royal Air Force maintains an operational fleet of various types of aircraft, described as being "leading-edge" in terms of technology. This largely consists of fixed-wing aircraft, including those in the following roles: fighter and strike, airborne early warning and control, intelligence, surveillance, target acquisition, and reconnaissance (ISTAR), signals intelligence (SIGINT), maritime patrol, air-to-air refueling (AAR) and strategic & tactical transport. The majority of their rotary-wing aircraft form part of the tri-service Joint Aviation Command in support of ground forces. Most of their aircraft and personnel are based in the UK, with many others serving on global operations (principally over Iraq and Syria) or at long-established overseas bases (Ascension Island, Cyprus, Gibraltar, and the Falkland Islands). Although they are the principal British air power arm, the Royal Navy's Fleet Air Arm and the British Army's Army Air Corps also operate armed aircraft.

Northern Ireland is a part of the United Kingdom in the north-east of the island of Ireland. It has been variously described as a constituent country, province or region. Northern Ireland shares an open border to the south and west with the Republic of Ireland. At the 2021 census, its population was 1,903,175, making up around 3% of the UK's population and 27% of the population on the island of Ireland. The Northern Ireland Assembly, established by the Northern Ireland Act 1998, holds responsibility for a range of devolved policy matters, while other areas are reserved for the UK Government. The government of Northern Ireland cooperates with the government of Ireland in several areas under the terms of the Good Friday Agreement. The Republic of Ireland also has a consultative role on non-devolved governmental matters through the British–Irish Intergovernmental Conference.

Adolf Hitler was an Austrian-born German politician who was dictator of Germany in the Nazi era from 1933 until his suicide in 1945. He rose to power as the leader of the Nazi Party, becoming the chancellor of Germany in 1933 and then taking the title of Führer und Reichskanzler in 1934. Germany's invasion of Poland on 1 September 1939 under his leadership marked the outbreak of the Second World War. Throughout the ensuing conflict, Hitler was closely involved in the direction of German military operations and was central to the perpetration of the genocide of about six million Jews in the Holocaust as well as the deaths of millions of other victims.

The Royal Canadian Air Force is the air and space force of Canada. Its role is to "provide the Canadian Forces with relevant, responsive and effective airpower". The RCAF is one of three environmental commands within the unified Canadian Armed Forces. As of 2020, the Royal Canadian Air Force consists of 12,074 Regular Force and 1,969 Primary Reserve personnel, supported by 1,518 civilians, and operates 258 manned aircraft and nine unmanned aerial vehicles. Appointed in 2025, Lieutenant-General Jamie Speiser-Blanchet is the current Commander of the Royal Canadian Air Force and Chief of the Air Force Staff.

Nazism, formally named National Socialism, is the far-right, ultranationalist, racist and totalitarian ideology associated with Adolf Hitler and the Nazi Party (NSDAP). It emerged in Germany during Hitler's rise to power and was frequently called Hitlerism. Nazism is a form of fascism that emphasizes pseudo-scientific theories of racial hierarchy which identify ethnic Germans and Nordic-Aryans as a master race. The term "neo-Nazism" is applied to far-right groups formed after World War II with a similar ideology.

The Reserve Bank of India (RBI) is the central bank of the Republic of India. It was established on April 1, 1935 by the British Raj, with enactment of the Reserve Bank of India Act, 1934. Although, the RBI is owned by the Government of India, the RBI is an autonomous regulatory organisation for the Indian banking & financial system with exercising substantial amount of independance and power over the Indian Economy. It is responsible for the issue, supply and control of the Indian rupee. It also manages the country's main payment systems & the foreign exchange under the FEMA Act, 1999. The RBI, along with the Indian Banks' Association, established the National Payments Corporation of India (NPCI) to promote and regulate the payment and settlement systems in India. Bharatiya Reserve Bank Note Mudran (BRBNM) is a specialised division of RBI through which it prints and mints Indian currency notes (INR) in two of its currency printing presses located in Mysore (Karnataka; Southern India) and Salboni (West Bengal; Eastern India). Deposit Insurance and Credit Guarantee Corporation was established by RBI as one of its specialized division for the purpose of providing insurance of deposits and guaranteeing of credit facilities to all Indian banks. The RBI is responsible for formulating and implementing India's monetary policy. The 2016 reform changed the decision-making framework from a Governor-centric model to a committee-based Monetary Policy Committee (MPC) model. It commenced its operations on 2 April 1935 in accordance with the Reserve Bank of India Act, 1934. The original share capital was divided into shares of 100 each fully paid. The RBI was nationalised on 1 January 1949, almost a year and a half after India's independence. The overall direction of the RBI lies with the 21-member central board of directors, composed of: the Governor; four Deputy Governors; two finance ministry representatives (usually the Economic Affairs Secretary and the Financial Services Secretary); ten government-nominated directors; and four directors who represent local boards for Mumbai, Kolkata, Chennai, and New Delhi. Each of these local boards consists of five members who represent regional interests and the interests of co-operative and indigenous banks. It is a member bank of the Asian Clearing Union. The bank is also active in promoting financial inclusion policy and is a leading member of the Alliance for Financial Inclusion (AFI). The bank is often referred to by the name "Mint Street".

Aden is an ancient port city in the southern part of the Arabian peninsula, on the north coast of the Gulf of Aden, positioned near the eastern approach to the Red Sea, and has been the de facto capital of the internationally recognized government of Yemen since 2014. It is approximately 170 km (110 mi) east of the Strait of Bab al-Mandab. With its strategic location on the coastline, Aden serves as a gateway between the Red Sea and the Arabian Sea, making it a crucial maritime hub connecting Africa, Asia, and the Middle East.

The Royal New Zealand Air Force (RNZAF; Māori: Te Tauaarangi o Aotearoa) is the aerial service branch of the New Zealand Defence Force. It was formed initially in 1923 as a branch of the New Zealand Army, being known as the New Zealand Permanent Air Force, becoming an independent air force on 1 April 1937. The RNZAF fought in World War II, Malaya, the Korean War, Vietnam and the Gulf War and has undertaken United Nations peacekeeping missions. From a peak of over 1,000 combat aircraft in 1945, the RNZAF has shrunk to a strength of 44 aircraft in 2026. It focuses on maritime patrol and transport duties in support of the Royal New Zealand Navy and the New Zealand Army. Its air combat capability ended in 2001, with the disbanding of the A-4 Skyhawk and Aermacchi MB-339 equipped squadrons. The Air Force is led by an Air Vice-Marshal who holds the appointment of Chief of Air Force. The RNZAF motto is the same as that of the Royal Air Force, Per Ardua ad Astra, meaning "Through Adversity to the Stars". The Māori language name Te Tauaarangi o Aotearoa, meaning "New Zealand Warriors of the Sky" or more literally "The New Zealand War Party of the Sky", was adopted in 2009; the name had been Te Hokowhitu o Kahurangi ("War Party of the Blue") for the previous 12 years.

World War II, or the Second World War, was a global conflict between two coalitions: the Allies and the Axis powers. Nearly all of the world's countries participated, with many engaging in total war on an unprecedented scale. World War II was the deadliest conflict in history, causing the deaths of 60 to 75 million people, a majority of whom were civilians. Millions died as a result of massacres, starvation, disease, and genocides, including the Holocaust. After the Allied victory, Germany, Austria, Japan, and Korea were occupied, and German and Japanese leaders were tried for war crimes.

The Tenth United States Army was the last army level command established during the Pacific War during World War II, and included divisions from both the U.S. Army and the U.S. Marine Corps.

The 1946 Aleutian Islands earthquake occurred near the Aleutian Islands, Alaska on April 1, 1946. The shock measured (Mw) 8.6, Mt 9.3 or (Ms) 7.4. It had a maximum Mercalli intensity of VI (Strong). The seafloor along the fault was elevated, triggering a Pacific-wide tsunami with multiple destructive waves at heights ranging from 45–138 ft (14–42 m), resulting in 165–173 casualties and over US$26 million (equivalent to $429,000,000 in 2025) in damage. The tsunami obliterated the Scotch Cap Lighthouse on Unimak Island, Alaska among others, and killed all five lighthouse keepers. Despite the damage to the Aleutian Island Unimak, the tsunami had an almost imperceptible effect on the Alaskan mainland.

The Malayan Union was a union of the Malay states and the Straits Settlements of Penang and Malacca. It was the successor to British Malaya and was conceived to unify the Malay Peninsula under a single government to simplify administration. Following opposition by the ethnic Malays, the union was reorganised as the Federation of Malaya in 1948.

The Cold War was a period of international geopolitical rivalry between the United States (US) and the Soviet Union (USSR) and their respective allies, the capitalist Western Bloc and communist Eastern Bloc. It began in the aftermath of the Second World War and ended with the dissolution of the Soviet Union in 1991. The term cold war is used because there was no direct fighting between the two superpowers, though each supported opposing sides in regional conflicts known as proxy wars. In addition to the struggle for ideological and economic influence and an arms race in both conventional and nuclear weapons, the Cold War was expressed through technological rivalries such as the Space Race, espionage, propaganda campaigns, embargoes, and sports diplomacy.

The Faroe Islands, also known as the Faroes, are an archipelago in the North Atlantic Ocean and a rigsdel of the Kingdom of Denmark. Located between Iceland, Norway, and the Hebrides and Shetland isles of Scotland, the islands have a population of 54,870 as of November 2025 and a land area of 1,393 km2 (538 sq mi). The official language is Faroese, which is partially mutually intelligible with Icelandic. The terrain is rugged, dominated by fjords and cliffs with sparse vegetation and few trees. As a result of their proximity to the Arctic Circle, the islands experience perpetual civil twilight during summer nights and very short winter days; nevertheless, they experience a subpolar oceanic climate and mild temperatures year-round due to the Gulf Stream. The capital, Tórshavn, receives the fewest recorded hours of sunshine of any city in the world at only 840 hours per year.

Dwight David "Ike" Eisenhower was the 34th president of the United States, serving from 1953 to 1961. In his previous military career, he commanded the Allied Expeditionary Force during World War II, including in Operation Torch in North Africa and Operation Overlord on D-Day in Normandy. For his distinguished service in the U.S. Army, Eisenhower was honored with the five-star rank of General of the Army.

The Ethniki Organosis Kyprion Agoniston was a Greek Cypriot nationalist guerrilla organization that fought a campaign for the end of British rule in Cyprus, and for eventual union with Greece.

Television InfraRed Observation Satellite (TIROS) is a series of early weather satellites launched by the United States, beginning with TIROS-1 in 1960. TIROS was the first satellite that was capable of remote sensing of the Earth, enabling scientists to view the Earth from a new perspective: space. The program, promoted by Harry Wexler, proved the usefulness of satellite weather observation, at a time when military reconnaissance satellites were secretly in development or use. TIROS demonstrated at that time that "the key to genius is often simplicity". TIROS is an acronym of "Television InfraRed Observation Satellite" and is also the plural of "tiro" which means "a young soldier, a beginner".

The Admiralty was a department of the Kingdom of Great Britain and from 1801 of the Government of the United Kingdom that was responsible for the command of the Royal Navy. Historically, its titular head was the Lord High Admiral – one of the Great Officers of State. For much of its history, from the early 18th century until its abolition, the role of the Lord High Admiral was almost invariably put "in commission" and exercised by the Lords Commissioner of the Admiralty, who sat on the governing Board of Admiralty, rather than by a single person. The Admiralty was replaced by the Admiralty Board in 1964, as part of the reforms that created the Ministry of Defence and its Navy Department.

The Hawker Siddeley Harrier is a British jet-powered attack aircraft designed and produced by the British aerospace company Hawker Siddeley. It was the first operational ground attack and reconnaissance aircraft with vertical/short takeoff and landing (V/STOL) capabilities and the only truly successful V/STOL design of its era.

Richard Milhous Nixon was the 37th president of the United States, serving from 1969 until his resignation in 1974. A member of the Republican Party, he represented California in both houses of the United States Congress before serving as the 36th vice president under President Dwight D. Eisenhower from 1953 to 1961. His presidency saw the reduction of U.S. involvement in the Vietnam War, détente with the Soviet Union and China, the Apollo 11 Moon landing, and the establishment of the Environmental Protection Agency and Occupational Safety and Health Administration. Nixon's second term ended early when he became the only U.S. president to resign from office, as a part of the Watergate scandal.

Royal Air Maroc is the Moroccan national carrier, as well as the country's largest airline, ranking among the largest in Africa.

The Bangladesh Liberation War, also known as the Bangladesh War of Independence, was an armed conflict sparked by the rise of the Bengali nationalist and self-determination movement in East Pakistan, which resulted in the independence of Bangladesh with the help of India. The war began when the Pakistani military junta based in West Pakistan—under the orders of Yahya Khan—launched Operation Searchlight against East Pakistanis on the night of 25 March 1971, initiating the Bangladesh genocide.

The Local Government Act 1972 is an act of the Parliament of the United Kingdom that reformed local government in England and Wales on 1 April 1974. It was one of the most significant acts of Parliament to be passed by the Heath Government of 1970–74.

Steven Paul Jobs was an American businessman, inventor, and investor. A pioneer of the personal computer revolution of the 1970s and 1980s, Jobs co-founded Apple Inc. with his early business partner Steve Wozniak as Apple Computer Company in 1976. After the company's board of directors fired him in 1985, he founded NeXT the same year and purchased Pixar in 1986, becoming its chairman and majority shareholder until 2007. Jobs returned to Apple in 1997 as CEO, where he was closely involved with the creation and promotion of many of the company's most influential products until his resignation in 2011.

Iran, officially the Islamic Republic of Iran, and historically known as Persia, is a country in West Asia. It borders Iraq to the west; Turkey, Azerbaijan, and Armenia to the northwest; the Caspian Sea to the north, Turkmenistan to the northeast; Afghanistan to the east; Pakistan to the southeast; and the Gulf of Oman and the Persian Gulf to the south. With a population of over 92 million, Iran ranks 17th globally in both geographic size and population. It is divided into five regions with 31 provinces. Tehran is the nation's capital and largest city and serves as its primary economic center.

Marvin Pentz Gaye Jr. was an American R&B and soul singer, songwriter, musician, and record producer. Commonly referred to as the "Prince of Motown" and "Prince of Soul", he helped to shape the sound of Motown and soul music in the 1960s and 1970s. A cultural icon, Gaye is often considered one of the greatest singers and songwriters of all time.

The Communist Party of Nepal (Mashal) was an underground communist party in Nepal. CPN (Mashal) was formed in November 1984, following a split in the Communist Party of Nepal (Masal). The new party was founded at a congress (labelled the 'fifth congress') in Gorakhpur, India. It was difficult to identify any major ideological difference between the two factions, and probably the split was caused by dissatisfaction with Singh's authoritarian leadership methods. Mohan Baidya (alias 'Kiran') became general secretary of the new party. Other Central Committee members elected at the Gorakhpur conference were Chitra Bahadur K.C., Ramsingh Shris, Bhairav Regmi, Govindsingh Thapa, Pushpa Kamal Dahal, Khambasingh Kubar, Bachaspati Devkota, C.P. Gajurel, Dev Gurung, Ishwari Dahal, Bishnu Pokhrel and Bhakta Bahadur Shrestha.

Margaret Hilda Thatcher, Baroness Thatcher was a British stateswoman who served as Prime Minister of the United Kingdom from 1979 to 1990 and Leader of the Conservative Party from 1975 to 1990. She was the longest-serving British prime minister of the 20th century and the first woman to hold the office. As prime minister, she implemented policies that came to be known as Thatcherism. A Soviet journalist dubbed her the "Iron Lady", a nickname that became associated with her uncompromising politics and leadership style.

Comet Hale–Bopp is a long-period comet that was one of the most widely observed of the 20th century and one of the brightest seen for many decades.
