La grève des prisonniers d'Ekibastouz (en russe : Экибасту́зская забастовка заключённых) est une grève qui se produisit dans la 6e division de Pestchanlag à Ekibastouz, au Kazakhstan, à la fin janvier 1952. Elle eut un grand retentissement du fait qu'elle sert de trame (en même temps que le soulèvement de Kengir) au scénario du film écrit en 1959 par Alexandre Soljenitsyne intitulé Les Tanks connaissent la vérité et à plusieurs chapitres (dont les chapitre 6 « Un évadé dans l'âme » et 11 « À tâtons nous rompons nos chaînes ») du troisième tome de L'Archipel du Goulag.

The Cairo fire (Arabic: حريق القاهرة‎), also known as Black Saturday, was a series of riots that took place on 26 January 1952, marked by the burning and looting of some 750 buildings—retail shops, cafes, cinemas, hotels, restaurants, theatres, nightclubs, and the city's Opera House—in downtown Cairo. The direct trigger of the riots was the killing by British occupation troops of 50 Egyptian auxiliary policemen in the city of Ismaïlia in a massacre one day earlier. The spontaneous anti-British protests that followed these deaths were quickly seized upon by organized elements in the crowd, who burned and ransacked large sectors of Cairo amidst the unexplained absence of security forces. The fire is thought by some to have signalled the end of the Kingdom of Egypt. The perpetrators of the Cairo Fire remain unknown to this day, and the truth about this important event in modern Egyptian history has yet to be established. The disorder that befell Cairo during the 1952 fire has recently been compared to the chaos that followed the anti-government protests of 25 January 2011, which saw demonstrations take place amidst massive arson and looting, an inexplicable withdrawal of the police and organized prison- breaking.

The 1952 steel strike was a strike by the United Steelworkers of America against U.S. Steel and nine other steelmakers. The strike was scheduled to begin on April 9, 1952, but US President Harry Truman nationalized the American steel industry hours before the workers walked out. The steel companies sued to regain control of their facilities. On June 2, 1952, in a landmark decision, the US Supreme Court ruled in Youngstown Sheet & Tube Co. v. Sawyer, 343 U.S. 579 (1952), that the President lacked the authority to seize the steel mills.

It was the first mass political action in Ceylon and the first major social crisis after independence. This event is of historical significance because it was the first people's struggle against an elected government in the country.

In December 1953, the British colonial government in Singapore passed the National Service Ordinance, requiring all male British subjects and Federal citizens between the ages of 18-20 to register for part-time National Service. The deadline for registration was on the 12th May 1954 and those who fail to register would either be jailed or fined. On the 12th May 1954, students from the Chinese Middle Schools still did not register themselves for National Service. In light of the impending deadline for registration and withrequests from the Chinese students, Chief Secretary William Goode would later meet representatives from the affected student body in the government house on 13 May 1954.

The Richard Riot was a riot on March 17, 1955 (Saint Patrick's Day), in Montreal, Quebec, Canada. The riot was named after Maurice Richard, the star ice hockey player for the Montreal Canadiens of the National Hockey League (NHL). Following a violent altercation on March 13 in which Richard hit a linesman, NHL president Clarence Campbell suspended him for the remainder of the 1954–55 NHL season, including the playoffs. Montreal fans protested that the suspension was too severe; the team's largely Francophone fan base claimed the length of the suspension was motivated by Richard's French Canadian ethnicity. Outside of Montreal, however, the suspension was seen as justified and, if anything, too short.

The Hock Lee bus workers' strike began on April 23, 1955. The incident was a result of failed negotiations between the Hock Lee Amalgamated Bus Company and its bus workers. The workers wanted better working conditions while the employers wanted to protect their business interests. The strikes eventually escalated and resulted in a clash among the Singapore Bus Workers Union, Hock Lee Employee's Union, the Singapore Chinese Middle Schools Student Union and law enforcement on May 12, 1955. The event has been commonly understood as a violent confrontation between colonialists and communists. The event was however also born out of the conditions of colonial society as well as being part of a necessary modernisation trajectory that Singapore was embarking on.

The Istanbul pogrom, also known as the Istanbul riots or September events (Greek: Σεπτεμβριανά Septemvriana, "Events of September"; Turkish: 6–7 Eylül Olayları, "Events of 6–7 September"), were organized mob attacks directed primarily at Istanbul's Greek minority on 6–7 September 1955. The riots were orchestrated by the Tactical Mobilisation Group, the special operations unit of the Turkish Army set up as Operation Gladio's Turkish branch;[dubious – discuss] the Counter- Guerrilla (another Operation Gladio-related organisation),[dubious – discuss] and the National Security Service, the predecessor of today's National Intelligence Organisation. The events were triggered by the false news that the day before, Greeks had bombed the Turkish consulate in Thessaloniki, in northern Greece—the house where Mustafa Kemal Atatürk had been born in 1881. A bomb planted by a Turkish usher at the consulate, who was later arrested and confessed, incited the events. The Turkish press, conveying the news in Turkey, was silent about the arrest and instead insinuated that Greeks had set off the bomb.

The events in Poland which led to the elimination of that country's Stalinist leadership and the rise to power of Władysław Gomułka on 19 October 1956 provoked unrest among university students in Eastern bloc countries. The state of unrest in Communist Poland began to spread into Hungary. As early as 16 October 1956, students from Szeged left the Communist-created students' union (DISZ), re-establishing the MEFESZ (Union of Hungarian University and Academy Students), a democratic organisation that the regime of Mátyás Rákosi had suppressed. Within a few days, students from Pécs, Miskolc and Sopron had done likewise. On 22 October 1956, students from the Budapest University of Technology and Economics compiled a list of sixteen points containing key national policy demands. When they found out about the intention of the Hungarian Writers' Union to express its solidarity with Poland by placing a crown near the statue of Polish general Józef Bem, a hero of the Hungarian revolution of 1848–49, the students decided to organise a parallel demonstration in support of the Poles. At the protest on the afternoon of 23 October 1956, the students read their proclamation, an act that marked the beginning of the Hungarian Revolution of 1956.

The steel strike of 1959 was a 116-day labor union strike (July 15 – November 7, 1959) by members of the United Steelworkers of America (USWA) that idled the steel industry throughout the United States. The strike occurred over management's demand that the union give up a contract clause which limited management's ability to change the number of workers assigned to a task or to introduce new work rules or machinery which would result in reduced hours or numbers of employees. The strike's effects persuaded President Dwight D. Eisenhower to invoke the back-to-work provisions of the Taft-Hartley Act. The union sued to have the Act declared unconstitutional, but the Supreme Court upheld the law.

The strike was instigated by the militant trade union, the General Labour Federation of Belgium (Fédération Générale du Travail de Belgique, or FGTB; Algemeen Belgisch Vakverbond, ABVV), against an attempt by the government of Gaston Eyskens to improve the state of Belgium's public finances by introducing a series of austerity measures known as the Unitary Law (Loi Unique or Eenheidswet). It has been described as "one of the most serious class confrontations in Belgium's social history", which brought out 700,000 workers out on strike. Although the strike began across Belgium, it soon lost momentum in Flanders where workers returned to work after a few days. The strike continued in Wallonia, a region already starting to experience deindustrialization, for several weeks. The law was eventually passed on 14 February 1961.
