"A las Barricadas" is sung to the tune of "Whirlwinds of Danger" ("Warszawianka"), composed by Józef Pławiński. The lyrics written by Valeriano Orobón Fernández in 1936 were partly based on the original Polish lyrics by Wacław Święcicki.

The anarchist movement in Chile emerged from European immigrants, followers of Mikhail Bakunin affiliated with the International Workingmen's Association, who contacted Manuel Chinchilla, a Spaniard living in Iquique. Their influence could be perceived at first within the labour unions of typographers, painters, builders and sailors. During the first decades of the 20th century, anarchism had a significant influence on the labour movement and intellectual circles of Chile. Some of the most prominent Chilean anarchists were: the poet Carlos Pezoa Véliz, the professor Dr Juan Gandulfo, the syndicalist workers Luis Olea, Magno Espinoza, Alejandro Escobar y Carballo, Ángela Muñoz Arancibia, Juan Chamorro, Armando Triviño and Ernesto Miranda, the teacher Flora Sanhueza, and the writers José Domingo Gómez Rojas, Fernando Santiván, José Santos González Vera and Manuel Rojas. At the moment, anarchist groups are experiencing a comeback in Chile through various student collectives, affinity groups, community and cultural centres, and squatting.

Its name is also sometimes rendered in English as the Bavarian Council Republic; the German term Räterepublik means a republic of councils or committees: council or committee is also the meaning of the Russian word soviet. It was established in April 1919 after the demise of Kurt Eisner's People's State of Bavaria and sought to establish a socialist soviet republic in Bavaria. It was overthrown less than a month later by elements of the German Army and the paramilitary Freikorps. Several individuals involved in its collapse later joined the Nazi Party during its subsequent rise to power.

The Besançon Commune was a short-lived revolutionary movement conceived and developed in 1871, aiming at the proclamation of a local autonomous power based on Lyon and Paris experiences. It originates from sociological upheavals which metamorphosed the city ·, and with the emergence of unions including a section of IWA in connection with the future Jura Federation · · · ·. The Franco-Prussian War, the fall of the Second Empire, and the advent of the Third Republic, precipitate events ·. While many notables testify to an insurrectional context and armed support from Switzerland is getting organized · ·, the correspondence left by James Guillaume and Mikhail Bakunin · attest to a planned release between the end of May and the beginning of June 1871. However, with the start of the Semaine sanglante on May 21 and the pursuit of an internal campaign until June 7, any attempt was seriously compromised. Despite the hope of a restart, the weeks and months following the idea of an insurrection is definitively abandoned reinforced by the extinction of the groups and activities called anarchists from 1875.

The inverted black triangle was an identification badge used in Nazi concentration camps to mark prisoners designated asozial ("asocial") and arbeitsscheu ("work-shy").

The trial resulted from the shooting, arrest, and beating by police of three anarchists, at a confrontation in Clichy on May 1, 1891, which was the first French, and international, celebration of International Workers' Day. Two of the three anarchists arrested were convicted and given harsh sentences.

"Don't mourn, organize!" is an expression, abridged from a statement by labor activist and songwriter Joe Hill near the time of his death. Hill wrote the full statement in a telegram he sent to Bill Haywood, which stated, "Goodbye, Bill, I die like a true blue rebel. Don't waste any time mourning. Organize!" Hill followed that telegram with another: "Could you arrange to have my body hauled to the state line to be buried? I don't want to be found dead in Utah." In 1915, Hill was convicted and executed for the murder of John and Arling Morrison a year prior; he denied having committed the murders but, for reasons that remain a source of speculation, was unwilling to give an alibi during his trial.

The Haymarket affair was the aftermath of a bombing that took place at a labor demonstration on May 4, 1886, at Haymarket Square in Chicago, Illinois, United States. It began as a peaceful rally in support of workers striking for an eight-hour work day, the day after police killed one and injured several workers.

The Industrial Workers of the World (IWW), members of which are commonly termed "Wobblies", is an international labor union that was founded in Chicago in 1905. The origin of the nickname "Wobblies" is uncertain. IWW ideology combines general unionism with industrial unionism, as it is a general union, subdivided between the various industries which employ its members. The philosophy and tactics of the IWW are described as "revolutionary industrial unionism", with ties to socialist, syndicalist, and anarchist labor movements.

An injury to one is an injury to all is a motto popularly used by the Industrial Workers of the World. In his autobiography, Bill Haywood credited David C. Coates with suggesting a labor slogan for the IWW: an injury to one is an injury to all. The slogan has since been used by a number of labor organizations. The slogan reflects the fact that the IWW is "One Big Union" and organizes skilled and unskilled workers. Despite the reduced number of organized workers today, the slogan is still popular with labor unions and other organizations. The core principles of NATO are also related to this.

The International Alliance of Socialist Democracy was an organisation founded by Mikhail Bakunin along with 79 other members on October 28, 1868 as an organisation within the International Workingmen's Association (IWA). The establishment of the Alliance as a section of the IWA was not accepted by the central committee of the IWA because international organisations were not allowed to join. The Alliance dissolved shortly afterwards and the former members instead joined their respective national sections of the IWA.

The International Workingmen's Association (IWA), often called the First International (1864–1876), was an international organisation which aimed at uniting a variety of different left-wing socialist, communist and anarchist groups and trade unions that were based on the working class and class struggle. It was founded in 1864 in a workmen's meeting held in St. Martin's Hall, London. Its first congress was held in 1866 in Geneva.

In 1968 and 1969, there were student protests at several Japanese universities that ultimately forced the closure of campuses nationwide. Known as daigaku funsō or daigaku tōsō, the protests were part of the worldwide protest cycle in 1968 and the late-1960s Japanese protest cycle, including the Anpo protests of 1970 and the struggle against the construction of Narita Airport. Students initially demonstrated against practical issues in universities, and they eventually formed the Zenkyōtō in mid-1968 to organize themselves. The protests were dispersed in 1969 by the Act on Temporary Measures concerning University Management.
The Kronstadt rebellion was a 1921 insurrection of Soviet sailors, soldiers and civilians against the Bolshevik government in the Russian SFSR port city of Kronstadt.

For sixteen days in March 1921, rebels in Kronstadt's naval fortress rose in opposition to the Soviet government they had helped to consolidate. Led by Stepan Petrichenko, it was the last major revolt against the Bolshevik regime on Russian territory during the Russian Civil War.

The Lyon Commune was a short-lived revolutionary movement in Lyon, France, in 1870 and 1871, by republicans and activists from several components of the far-left of the time who seized power in Lyon and established autonomous power. The commune organized elections and dissolved after a republican normality was restored, which frustrated the most radical elements, who hoped for a different revolution. The latter twice tried to regain power without success. This happened as part of a revolutionary wave that culminated with the 1871 Paris Commune.
The Macedonian Secret Revolutionary Committee (MSRC) was founded in 1895 in Plovdiv. It was developed later in Geneva in a secret, anarchistic, brotherhood called "Geneva group".

The Black Hand was a presumed secret, anarchist organization based in the Andalusian region of Spain and best known as the perpetrators of murders, arson, and crop fires in the early 1880s. The events associated with the Black Hand took place in 1882 and 1883 amidst class struggle in the Andalusian countryside, the spread of anarcho-communism distinct from collectivist anarchism, and differences between legalists and illegalists in the Federación de Trabajadores de la Región Española.

Beginning in May 1968, a period of civil unrest occurred throughout France, lasting some seven weeks and punctuated by demonstrations, general strikes, as well as the occupation of universities and factories. At the height of events, which have since become known as May 68, the economy of France came to a halt. The protests reached such a point that political leaders feared civil war or revolution; the national government briefly ceased to function after President Charles de Gaulle secretly fled France to Germany at one point. The protests are sometimes linked to similar movements that occurred around the same time worldwide and inspired a generation of protest art in the form of songs, imaginative graffiti, posters, and slogans.

The Milwaukee Police Department bombing was a November 24, 1917, bomb attack that killed ten people including nine members of local law enforcement. The perpetrators were never caught but are suspected to be an anarchist terrorist cell operating in the United States in the early 20th century. The target was initially an evangelical church in the Third Ward and only killed the police members when the bomb was taken to the police station by a concerned member of the public. The bombing remained the most fatal single event in national law enforcement history for over 80 years until the 9-11 attacks.

No gods, no masters is an anarchist and labour slogan. It has been in common use by anarchists and socialists in Europe since the late 19th century. The journal Commonweal, for instance, includes an article by John Creaghe from Sheffield in which he records that the Sheffield Telegraph newspaper "was furious when it found we were Anarchists with 'Neither God nor Master' for our motto". An early 20th century usage as a labour slogan is evident in a pamphlet handed out by the Industrial Workers of the World during the 1912 Lawrence Textile Strike. The phrase is derived from the French slogan "Ni dieu ni maître !" coined by the socialist Louis Auguste Blanqui in 1880, when he published a journal by that name. In Joseph Conrad's novel The Secret Agent, first published in 1907, the anarchist character The Professor says: "My device is: No God! No master."

Patagonia Rebelde was the name given to the uprising and violent suppression of a rural workers' strike in the Argentine province of Santa Cruz in Patagonia between 1920 and 1922. The uprising was put down by Colonel Héctor Benigno Varela's 10th Cavalry Regiment of the Argentine Army under the orders of President Hipólito Yrigoyen. Approximately 300-1,500 rural workers were shot and killed by the 10th Cavalry Regiment in the course of the operations, many of them executed by firing squads after surrendering. Most of the executed were Spanish and Chilean workers who had sought refuge in Argentina's Patagonia after their violent strike in the city of Puerto Natales in southern Chile on 27 July 1920 was crushed by the Chilean authorities, at the cost of four carabiniers killed. At least two Argentine soldiers, three local policemen and a number of ranch owners and their relatives also died during the strife. Several of the captured women were raped in the uprising as the rebel forces fought for control of the territory. The most detailed narrative of these events is that by Osvaldo Bayer, summarized in English by Bruce Chatwin in 1976.

Pistolerismo refers to the practice used by Spanish employers during King Alfonso XIII's reconstruction crisis of hiring thugs to face syndicalists and notable workers – and vice versa. The workers replied in turn by hiring their own gunmen. In the end, pistolerismo caused the death of 200 workers and 20 employers' gunmen.

Anarchism as a social movement is one of the manifestations of the political left within the working classes of Puerto Rico, having its peak during the late 19th and early 20th century. Anarchism was predominantly present within, but not exclusive to, the working classes that emerged as the sociopolitical environment changed. The municipalities of Caguas and Bayamón were the epicenters of the movement. It was also recorded in other industrial centers, such as Ponce, San Juan, Arecibo, Cayey, Cidra, Juncos, Vega Baja, Utuado, Lares, Yauco and Mayagüez. Despite sharing some core values, Puerto Rican anarchism was heterogeneous in nature. In general, Puerto Rican anarchism was distinctly anti-organized religion, in particular against the Catholic Church that had retained considerable influence since the beginning of Spanish colonialism. Following the Treaty of Paris, it also grew to oppose American sovereignty, as it perceived that the island was being forced into servitude with an Americanization initiative, leading to distinct antiauthoritarian stances against both foreign and local politicians, the wealthy higher classes and American labor unions. However, on principle the anarchists opposed joining the independence movement.

Alois Rašín was a Czech and Czechoslovakian politician, economist, one of the founders of Czechoslovakia and first Ministry for Finance.

They protected the operation of "free soviets" and libertarian communes in the Free Territory, an attempt to form a stateless libertarian communist society from 1918 to 1921 during the Ukrainian War of Independence. They were founded and inspired based on the Black Guards.

The Revolutions of 1917–1923 was a revolutionary wave that included political unrest and revolts around the world inspired by the success of the Russian Revolution and the disorder created by the aftermath of World War I. The uprisings were mainly socialist or anti-colonial in nature. Some socialist revolts failed to create lasting socialist states. The revolutions had lasting effects in shaping the future European political landscape, with for example the collapse of the German Empire and the abdication of the German Kaiser.

Fermín Salvochea y Álvarez was a mayor of the city of Cádiz and a president of the province of Cádiz. He was one of the main propagators of anarchist thought in that area in the late 19th century and is considered to be "perhaps the most beloved figure in the Spanish Anarchist movement of the 19th century". Being a prominent republican, in 1871, he joined the First International. In 1873, he was elected president of the administrative committee of Cádiz Province.

Socialist Sunday Schools (SSS) were set up to replace or augment Christian Sunday Schools in the United Kingdom, and later the United States. They arose in response to the perceived inadequacy of orthodox Sunday schools as a training ground for the children of socialists and the need for an organised, systematic presentation of the socialist point of view to teach the ideals and principles of socialism to children and young people.

Solidaridad Obrera was a labor federation in Catalonia, Spain. It was initially formed on August 3, 1907, as a "pure syndicalist" federation, incorporating the structures of the Unió Local de Societats Obreres de Barcelona with the purpose of reorganizing the Catalan trade unions. These unions were quite weak at the time, due to the failure of a 1902 general strike which had sought the eight-hour day and the recognition of the right to strike.
Solidaridad Obrera is a newspaper, published by the Catalan/Balearic regional section of the anarchist labor union Confederación Nacional del Trabajo (CNT), and mouthpiece of the CNT in Spain.

Tragic Week was a series of violent confrontations between the Spanish army and anarchists, socialists and republicans of Barcelona and other cities in Catalonia, Spain, during the last week of July 1909. It was caused by the calling-up of reserve troops by Premier Antonio Maura to be sent as reinforcements when Spain renewed military-colonial activity in Morocco on 9 July, in what is known as the Second Rif War. Many of these reservists were the only breadwinners for their families, while the wealthy were able to hire substitutes.
