The Poplar Rates Rebellion, or Poplar Rates Revolt, was a tax protest that took place in Poplar, London, England, in 1921. It was led by George Lansbury, the previous year's Labour Mayor of Poplar, with the support of the Poplar Borough Council, most of whom were industrial workers. The protest defied government, the courts, and the Labour Party leadership. George Lansbury would later go on to be the leader of the Labour Party.

The Tulsa race massacre (also called the Tulsa race riot, the Greenwood Massacre, the Black Wall Street Massacre, or the Tulsa Massacre) took place on May 31 and June 1, 1921, when mobs of white residents, many of them deputized and given weapons by city officials, attacked black residents and businesses of the Greenwood District in Tulsa, Oklahoma. It has been called "the single worst incident of racial violence in American history." The attack, carried out on the ground and from private aircraft, destroyed more than 35 square blocks of the district—at that time the wealthiest black community in the United States, known as "Black Wall Street".

The Jaffa riots (commonly known in Hebrew: מאורעות תרפ"א‎, romanized: Me'oraot Tarpa) was a series of violent riots in Mandatory Palestine on May 1–7, 1921, which began as a fight between two Jewish groups but developed into an attack by Arabs on Jews during which many were killed. The rioting began in Jaffa and spread to other parts of the country. The riot resulted in the deaths of 47 Jews and 48 Arabs. Another 146 Jews and 73 Arabs were wounded.

The March on Rome (Italian: Marcia su Roma) was an organized mass demonstration in October 1922, which resulted in Benito Mussolini's National Fascist Party (Partito Nazionale Fascista, or PNF) ascending to power in the Kingdom of Italy (Regno d'Italia). In late October 1922, Fascist Party leaders planned an insurrection, to take place on 28 October. When fascist troops entered Rome, Prime Minister Luigi Facta wished to declare a state of siege, but this was overruled by King Victor Emmanuel III. On the following day, 29 October 1922, the King appointed Mussolini as Prime Minister, thereby transferring political power to the fascists without armed conflict.

The Seamen's Strike of 1922 began on 12 January 1922, when Chinese seamen from Hong Kong and Canton (now Guangzhou) went on strike for higher wages. Led by the Seamen's Union after shipping companies refused to increase salaries by 40%, the strike quickly garnered over 30,000 participants, greatly disrupting everyday colonial life and food shipments to Hong Kong. Though the strike was declared illegal by the Hong Kong government, negotiations eventually took place after 52 days, with employers capitulating on 5 March 1922 and agreeing to wage increases of 15–30%.

The Italian general strike of October 1922 was a general strike against Benito Mussolini's power- grab with the March on Rome. It was led by socialists and ended in defeat for the workers. Mussolini famously referred to this as the "Caporetto of Italian Socialism".

Demonstrators took control of the Main Market Square area and disarmed some troops. Eventually troops and police were ordered to fire on the workers, though some soldiers refused. Three armored cars were used, one of which, named Dziadek ("Grandpa"), was captured by the workers in the Market Square area. Some 18–30 workers were killed, as well as 14 soldiers. No policemen died, but 31 were injured.

Some 1.7 million workers went out, especially in transport and heavy industry. The government was prepared, and enlisted middle class volunteers to maintain essential services. There was little violence and the TUC gave up in defeat.

The Nagpur riots of 1927 were part of series of riots taking place across various cities in British India during the 1920s. Nagpur was then the capital of Central Provinces and Berar (CP&B) state of British India which covered most of the central India. The riots occurred on 4 September 1927. On that day, there was a procession for Mahalakshmi, which is said to have been blocked by Muslims when it came to the Mahal neighbourhood. In the afternoon, there was rioting near the Hindu houses of the neighbourhood, which continued for three days.

Both Nationalist and Communist soldiers within the NRA participated in the rioting and looting of foreign-owned property in Nanjing.

The 1927 Indiana bituminous strike was a strike by members of the United Mine Workers of America (UMWA) against local bituminous coal companies. Although the struggle raged throughout most of the nation's coal fields, its most serious impact was in western Pennsylvania, including Indiana County. The strike began on April 1, 1927, when almost 200,000 coal miners struck the coal mining companies operating in the Central Competitive Field, after the two sides (management and labor) could not reach an agreement on pay rates. The UMWA was attempting to retain pay raises gained in the contracts it had negotiated in 1922 and 1924, while management, stating that it was under economic pressure from competition with the West Virginia coal mines, was seeking wage reductions. The strike proved to be a disaster for the union, as by 1929, there were only 84,000 paying members of the union, down from 400,000 which belonged to the union in 1920.

The 1928 South Indian railway strike was a general strike by the South Indian Railway Workers Union against plans of the South Indian Railway Company to lay off over 3,100 workers in order to reduce the expenditures of the company. The strike lasted from 29 June – 2 August 1928, and severely affected the transportation of people and goods across South India. The Madras government and the South Indian Railway Company responded with a crackdown. Most of the leaders of the strike were arrested and recognition to the union was withdrawn.The Government of Madras recorded it as the "most important event of the year".

The 1928 New Bedford textile strike was a mass work stoppage of approximately 30,000 machinery operatives in several of the large cotton mills located in New Bedford, Massachusetts, USA. The strike, which ran for several months during the spring and summer of 1928, is remembered for the prominent role played by the Workers (Communist) Party of America in mobilizing the immigrant workers of the region.

The Cantaloupe strike of 1928 was labor movement of cantaloupe pickers in Imperial Valley, California. On May 7, 1928 cantaloupe pickers walked off of the job and the strike lasted to May 10 of the same year. The strikers had hardly any outside support and many were effectively imprisoned by local police for gathering together in any public space during the strike. The strikers were mostly Mexican immigrants or of Mexican descent because they comprised the vast majority of produce laborers in California, about 3,500 to 4,000 Mexicans worked as cantaloupe pickers. While the strike was short-lived and seemingly unorganized, it stands as a victory for the workers.

The 1929 Timber Workers strike was a labour dispute in Australia caused by Judge Lukin of the Arbitration Court handing down an industrial award decision on 23 December 1928 to reduce the wages and increase the hours for 20,000 timber workers from a 44-hour week to a 48-hour week. It was the first strike in Australia after the onset of the Great Depression.

The Women's War, or Aba Women's Riots (Igbo: Ogu Umunwanyi; Ibibio: Ekong Iban), was a period of unrest in British Nigeria over November 1929. The protests broke out when thousands of Igbo women from the Bende District, Umuahia and other places in eastern Nigeria traveled to the town of Oloko to protest against the Warrant Chiefs, whom they accused of restricting the role of women in the government. The Aba Women's Riots of 1929, as it was named in British colonial records, is more aptly considered a strategically executed anti- colonial revolt organised by women to redress social, political and economic grievances. The protest encompassed women from six ethnic groups (Ibibio, Andoni, Orgoni, Bonny, Opobo, and Igbo). It was organised and led by the rural women of Owerri and Calabar provinces. During the events, many Warrant Chiefs were forced to resign and 16 Native Courts were attacked, most of which were destroyed. It was the first major anti- colonial revolt by women in West Africa. In 1930 the colonial government abolished the system of warrant chieftains, and appointed women to the Native Court system. These reforms were built upon by the African women and have been seen as a prelude to the emergence of mass African anti- colonial nationalism.

The Hebron massacre refers to the killing of sixty-seven or sixty-nine Jews on 24 August 1929 in Hebron, then part of Mandatory Palestine, by Arabs incited to violence by rumors that Jews were planning to seize control of the Temple Mount in Jerusalem. The event also left scores seriously wounded or maimed. Jewish homes were pillaged and synagogues were ransacked. Some of the 435 Jews who survived were hidden by local Arab families, although the extent of this phenomenon is debated. Soon after, all Hebron's Jews were evacuated by the British authorities. Many returned in 1931, but almost all were evacuated at the outbreak of the 1936–39 Arab revolt in Palestine. The massacre formed part of the 1929 Palestine riots, in which a total of 133 Jews and 110 Arabs were killed, and brought the centuries-old Jewish presence in Hebron to an end.

The 1930 Rangoon riots were a pair of race riots between Indian dockworkers and Burman labourers. The first broke out on 26 May near the Rangoon docks. It spread to nearby districts with high Indian populations and resulted in over one hundred killed and about one thousand injured. The second, a prison riot, began on 24 June in Rangoon Central Jail, where the staff was predominantly Indian and the inmates overwhelmingly Burman. The riots were overshadowed by the Saya San rebellion that erupted in December that year.

The Salt March, also known as the Salt Satyagraha, Dandi March and the Dandi Satyagraha, was an act of nonviolent civil disobedience in colonial India led by Mohandas Karamchand Gandhi. The 24-day march lasted from 12 March 1930 to 6 April 1930 as a direct action campaign of tax resistance and nonviolent protest against the British salt monopoly. Another reason for this march was that the Civil Disobedience Movement needed a strong inauguration that would inspire more people to follow Gandhi's example. Mahatma Gandhi started this march with 79 of his trusted volunteers. Walking ten miles a day for 24 days, the march spanned over 240 miles (384 km), from Sabarmati Ashram to Dandi, which was called Navsari at that time (now in the state of Gujarat). Growing numbers of Indians joined them along the way. When Gandhi broke the salt laws at 6:30 am on 6 April 1930, it sparked large scale acts of civil disobedience against the British Raj salt laws by millions of Indians.

The Jewish exodus from Arab and Muslim countries, or Jewish exodus from Arab countries, was the departure, flight, expulsion, evacuation and migration of 850,000 Jews, primarily of Sephardi and Mizrahi background, from Arab countries and the Muslim world, mainly from 1948 to the early 1970s.

Talonpoikaismarssi (ruots. Bondetåget) oli Helsingissä 7. heinäkuuta 1930 järjestetty äärioikeistolaisen Lapuan liikkeen mielenosoitus, johon osallistui yli 12 000 eri puolilta maata saapunutta järjestön kannattajaa. Se oli Lapuan liikkeen lyhyeksi jääneen historian merkittävin voimannäyttö, joka oli suunnattu ensisijaisesti kommunisteja vastaan, mutta sen tarkoituksena oli myös painostaa Suomen hallitusta. Senaatintorilla pidetyn pääjuhlan kutsuvieraina oli muun muassa presidentti L. K. Relander, pääministeri P. E. Svinhufvud hallituksineen sekä oikeistopuolueiden kansanedustajia, maan sotilasjohtoa ja sisällissodan valkoisen armeijan ylipäällikkö kenraali C. G. E. Mannerheim. Ulkoisilta piirteiltään talonpoikaismarssi muistuttikin 16. toukokuuta 1918 järjestettyä valkoisten voitonparaatia, jota sen reitti myös noudatti.
