Anarchism and Esperanto are strongly linked because of their common ideals of social justice and equality. During the early Esperanto movement, anarchists enthusiastically publicized the language, and the two movements have much common history.
Anarchists were among the first to publicize Esperanto. In 1905, the first Esperanto anarchist group was founded in Stockholm. Many others followed: in Bulgaria, China, and other countries. Anarchists and anarcho-syndicalists (who belonged to the largest group of proletarian Esperantists before World War I) founded Paco-Libereco (Peace-Freedom),[1] an international league which published the newspaper Internacia Socia Revuo (International Society Review). Paco-Libereco merged with another progressive association, Esperantista Laboristaro (Esperanto Workers). The new organization was called Liberiga Stelo (Freeing Star).[2] Until 1914, that organization published revolutionary literature in Esperanto, including anarchist literature.
In March of 1925, the Berlin Group of Anarcho-Syndicatist Esperantists ("Berlina Grupo de Anarki-Sindikatismaj Esperantistoj") met with the 2nd Congress of the International Labor Association (ILA) in Amsterdam. The Esperanto labor movement was particularly strong in Germany and the Soviet Union. In 1923, the International Scientific Anarchist Library of the International Language ("Internacian Sciencan Anarkiisman Bibliotekon de la Internacia Lingvo") was founded in Soviet Ukraine, publishing Peter Kropotkin's books in Esperanto, aimed for international reading.
After World War II, the Paris group was the first to restart organized labor. Starting in 1946, it published the newspaper Senŝtatano (person without a country).[3]
