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 create by the Territorial and Reserve Forces Act 1907, 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.

The Fântâna Albă massacre took place on 1 April 1941 in Northern Bukovina when up to 200 civilians were killed by Soviet Border Troops as they attempted to cross the border from the Soviet Union to Romania near the village of Fântâna Albă, now Staryi Vovchynets in Chernivtsi Oblast, Ukraine. Although according to Soviet official reports, no more than 44 civilians were killed, but local witnesses assert a much higher toll, stating that survivors were tortured, killed, or buried in mass graves. Others were taken away to be tortured and killed at the hands of the NKVD, the Soviet secret police. The Romanian media generally claims exaggerated figures of 2,000 to 3,000 victims, sometimes also claiming, falsely, that the incident occurred during Easter. Some sources have referred to the massacre as "the Romanian Katyn".

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. Tanks and aircraft played major roles, the latter enabling the strategic bombing of cities and delivery of the only nuclear weapons used in war. World War II was the deadliest conflict in history, causing the death of 60 to 75 million people. 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 1946 Aleutian Islands earthquake occurred near the Aleutian Islands, Alaska on April 1, 1946. The shock measured 8.6, Mt 9.3 or 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 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.

During April 1947, the Royal New Zealand Navy (RNZN) experienced a series of non-violent mutinies amongst the enlisted sailors of four ships and two shore bases. Over 20 per cent of the RNZN's enlisted personnel were punished or discharged for their involvement. The main cause was the poor rates of pay compared to the rest of the New Zealand Defence Force and equivalent civilian wages, exacerbated by the release of a long overdue government review which failed to address the issue. Sailors saw the new pay rates as still inferior to the other branches of the military, with the increases being consumed by taxes, inflation, and the cancellation of allowances and benefits. The poor living and working conditions aboard RNZN ships was another issue, compounded by sailors having no effective way to make dissatisfaction known to the higher ranks. Dissatisfaction with peacetime duties and opportunities also contributed, with many sailors locked into enlistment periods of up to 12 years, and demobilisation efforts prioritising those enlisted specifically for the duration of the Second World War.

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 per year.

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 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.
