An acqua alta is an exceptional tide peak that occurs periodically in the northern Adriatic Sea. The term is applied to such tides in the Italian region of Veneto. The peaks reach their maximum in the Venetian Lagoon, where they cause partial flooding of Venice and Chioggia; flooding also occurs elsewhere around the northern Adriatic, for instance at Grado and Trieste, but much less often and to a lesser degree.

The 1966 Venice flood was an unprecedented high water, known in Venice as an "acqua alta", with waters reaching up to 194 cm.

Florence is the capital city of the Italian region of Tuscany. It is also the most populated city in Tuscany, with 362,353 inhabitants, and 989,460 in its metropolitan province as of 2025.

The 1966 flood of the Arno in Florence killed 35 people and damaged or destroyed millions of masterpieces of art and rare books. It is considered the worst flood in the city's history since 1557. With the combined effort of Italian and foreign volunteers alike, or angeli del fango, many of these fine works have been restored. New methods in conservation were devised and restoration laboratories established. However, even decades later, much work remains to be done.

The Arno is a river in the Tuscany region of Italy. It is the most important river of central Italy after the Tiber.

The Partial Test Ban Treaty (PTBT), formally known as the 1963 Treaty Banning Nuclear Weapon Tests in the Atmosphere, in Outer Space and Under Water, prohibited all test detonations of nuclear weapons except for those conducted underground. It is also abbreviated as the Limited Test Ban Treaty (LTBT) and Nuclear Test Ban Treaty (NTBT), though the latter may also refer to the Comprehensive Nuclear-Test-Ban Treaty (CTBT), which succeeded the PTBT for ratifying parties.

Nuclear weapons tests are experiments carried out to determine the performance of nuclear weapons and the effects of their explosion. Over 2,000 nuclear weapons tests have been carried out since 1945. Nuclear testing is a sensitive political issue. Governments have often performed tests to signal strength. Because of their destruction and fallout, testing has seen opposition by civilians as well as governments, with international bans having been agreed on. Thousands of tests have been performed, with most in the second half of the 20th century.

Operation Fishbowl was a series of high-altitude nuclear tests in 1962 that were carried out by the United States as a part of the larger Operation Dominic nuclear test program.

Dame Valerie Jane Morris Goodall was an English primatologist and anthropologist. Regarded as a pioneer in primate ethology, and described by many publications as "the world's preeminent chimpanzee expert", she was best known for more than six decades of field research on the social and family life of wild chimpanzees in the Kasakela chimpanzee community at Gombe Stream National Park in Tanzania. Beginning in 1960, under the mentorship of the palaeontologist Louis Leakey, Goodall's research demonstrated that chimpanzees share many key traits with humans, such as using tools, having complex emotions, forming lasting social bonds, engaging in organised warfare, and passing on knowledge across generations, which redefined the traditional view that humans are uniquely different from other animals.

The Hungarian Revolution of 1956, also known as the Hungarian Uprising, was an attempted countrywide revolution against the government of the Hungarian People's Republic (1949–1989) and the policies caused by the government's subordination to the Soviet Union (USSR). The uprising lasted 15 days before being crushed by Soviet tanks and troops on 7 November 1956. Thousands were killed or wounded, and nearly a quarter of a million Hungarians fled the country.

The Kasekela chimpanzee community is a habituated community of wild eastern chimpanzees that lives in Gombe National Park near Lake Tanganyika in Tanzania. The community was the subject of Jane Goodall's pioneering study that began in 1960, and studies have continued ever since, becoming the longest continuous study of any animals in their natural habitat. As a result, the community has been instrumental in the study of chimpanzees and has been popularized in several books and documentaries. The community's popularity was enhanced by Goodall's practice of giving names to the chimpanzees she was observing, in contrast to the typical scientific practice of identifying the subjects by number. Goodall generally used a naming convention in which infants were given names starting with the same letter as their mother, allowing the recognition of matrilineal lines.

The Hungarian People's Republic (HPR) was a landlocked country in Central Europe from its formation on 20 August 1949 until the establishment of the current Republic of Hungary on 23 October 1989.

Nearly all of the world's countries participated, with many nations mobilising all resources in pursuit of total war. Tanks and aircraft played major roles, enabling the strategic bombing of cities and delivery of the first and only nuclear weapons ever used in war. World War II is the deadliest conflict in history, causing the death of 70 to 85 million people, more than half of whom were civilians. Millions died in genocides, including the Holocaust, and by massacres, starvation, and disease. After the Allied victory, Germany, Austria, Japan, and Korea were occupied, and German and Japanese leaders were tried for war crimes.

The Confederación Nacional del Trabajo is a Spanish anarcho-syndicalist trade union confederation.

Anarcho-syndicalism is an anarchist organisational model that centres trade unions as a vehicle for class conflict. Drawing from the theory of libertarian socialism and the practice of syndicalism, anarcho-syndicalism sees trade unions as both a means to achieve immediate improvements to working conditions and to build towards a social revolution in the form of a general strike, with the ultimate aim of abolishing the state and capitalism. Anarcho-syndicalists consider trade unions to be the prefiguration of a post-capitalist society and seek to use them in order to establish workers' control of production and distribution. An anti-political ideology, anarcho-syndicalism rejects political parties and participation in parliamentary politics, considering them to be a corrupting influence on the labour movement. In order to achieve their material and economic goals, anarcho-syndicalists instead practice direct action in the form of strike actions, boycotts and sabotage. Anarcho-syndicalists also attempt to build solidarity among the working class, in order to unite workers against the exploitation of labour and build workers' self-management.

A war cabinet is a committee formed by a government in a time of war to efficiently and effectively conduct that war. It is usually a subset of the full executive cabinet of ministers, although it is quite common for a war cabinet to have senior military officers and opposition politicians as members.

A cabinet reshuffle or shuffle occurs when a head of government rotates or changes the composition of ministers in their cabinet, or when the head of state changes the head of government and a number of ministers. They are more common in parliamentary systems than in systems where cabinet heads must be confirmed by a separate legislative body, and occur frequently in autocratic systems.

Francisco Largo Caballero was a Spanish politician and trade unionist who served as the prime minister of the Second Spanish Republic during the Spanish Civil War. He was one of the historic leaders of the Spanish Socialist Workers' Party (PSOE) and of the Workers' General Union (UGT). Although he entered politics as a moderate leftist, after the 1933 general election in which the conservative CEDA party won the majority, he took a more radical turn and began to advocate for a socialist revolution, materialized with the failed Revolution of 1934 in Asturias.

The Spanish Civil War was fought from 1936 to 1939 between the Republicans and the Nationalists. Republicans were loyal to the left-leaning Popular Front government of the Second Spanish Republic and included socialists, anarchists, communists, and separatists. The opposing Nationalists who established the Spanish State were an alliance of fascist Falangists, monarchists, conservatives, and traditionalists supported by Nazi Germany and Fascist Italy and led by a military junta among whom General Francisco Franco quickly achieved a preponderant role. Due to the international political climate at the time, the war was variously viewed as class struggle, a religious struggle, or a struggle between dictatorship and republican democracy, between revolution and counterrevolution, or between fascism and communism. The Nationalists won the war, which ended in early 1939, and ruled Spain until Franco's death in November 1975.
