The Menai Suspension Bridge is a suspension bridge spanning the Menai Strait between the island of Anglesey and the mainland of Wales. Designed by Thomas Telford and completed in 1826, it was one of the world's first major suspension bridges, and second such bridge designed to carry vehicular traffic, after the Union Chain Bridge (1820) across the River Tweed. The bridge still carries road traffic and is a Grade I listed structure.

Yerba Buena was an anchorage spot and later a settlement that grew into the city of San Francisco, California. The settlement, built in an area known earlier as El Paraje de Yerba Buena and named for an herb that grew abundantly there, was founded in 1834 and was located near the northeastern end of the San Francisco Peninsula, on the shores of Yerba Buena Cove. Yerba Buena was the first Spanish colonial or Mexican civilian settlement in San Francisco, which had previously only had indigenous, missionary, and military settlements, and was originally intended as a trading post for ships visiting San Francisco Bay. The settlement was arranged in the Spanish style around a plaza that remains as the present day Portsmouth Square. The area that was the Yerba Buena settlement is now in the Financial District and Chinatown neighborhoods of San Francisco.

The American Civil War was a civil war in the United States between the Union and the Confederacy, which was formed in 1861 by states that had seceded from the Union to preserve slavery in the United States, which they saw as threatened because of the election of Abraham Lincoln and the growing abolitionist movement in the North. The war ended with Union victory, the dissolution of the Confederacy and the abolition of slavery, freeing four million African Americans.

The Anglo-Japanese Alliance was an alliance between the United Kingdom and the Empire of Japan which was effective from 1902 to 1923. The treaty creating the alliance was signed at Lansdowne House in London on 30 January 1902 by British foreign secretary Henry Petty-Fitzmaurice, 5th Marquess of Lansdowne and Japanese diplomat Hayashi Tadasu. After the preceding era of unequal treaties enforced on Asian countries including Japan, the alliance was a military pact concluded on more equal terms between a Western power and non-Western nation. It reflected the success of Meiji era reforms that modernized and industrialized Japan's economy, society and military, which enabled Japan to extract itself from the inferior position it had previously shared with other Asian countries like China, which had been subordinated to Western empires either through formal colonial acquisition or unequal treaties.

The rise to power of Adolf Hitler, the dictator of Germany during the Nazi era from 1933 until his suicide in 1945, began in the newly established Weimar Republic in September 1919, when Hitler joined the Deutsche Arbeiterpartei. He quickly rose to a place of prominence and became one of its most popular speakers. In an attempt to more broadly appeal to larger segments of the population and win over German workers, the party name was changed to the Nationalsozialistische Deutsche Arbeiterpartei, commonly known as the Nazi Party, and a new platform was adopted. Hitler was made the party leader in 1921 after he threatened to otherwise leave. By 1922, his control over the party was unchallenged. The Nazis were a right-wing party, but in the early years they also had anti-bourgeois elements. Hitler later initiated a purge of these elements and reaffirmed the Nazi Party's support for collaboration with German businesses. This included killings of Hitler's critics within the party during the Night of the Long Knives, which also served as a tool to secure power.

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, Soviet-occupied Poland, Czechoslovakia, Hungary, Latvia and Lithuania.Japan, and Korea were occupied, and German and Japanese leaders were tried for war crimes.

British South American Airways (BSAA) was a state-run airline of the United Kingdom in the mid-to-late 1940s responsible for services to the Caribbean and South America.

BSAA operated mostly Avro aircraft: Yorks, Lancastrians and Tudors and flew to Bermuda, the West Indies, Mexico and the western coast of South America.

The civil rights movement was a social movement in the United States from 1954 to 1968 which aimed to abolish legalized racial segregation, discrimination, and disenfranchisement in the country, which most commonly affected African Americans. The movement had origins in the Reconstruction era in the late 19th century, and modern roots in the 1940s and in Mohandas Gandhi's nonviolent movement in India. After years of nonviolent protests and civil disobedience campaigns, the civil rights movement achieved many of its legislative goals in the 1960s, during which it secured new protections in federal law for the civil rights of all Americans, including the Civil Rights Act of 1964, the Voting Rights Act of 1965, and the Civil Rights Act of 1968.
