Justice Commandos of the Armenian Genocide (JCAG) (Armenian: Հայկական Ցեղասպանութեան Արդարութեան Մարտիկներ, ՀՑԱՄ) was an Armenian militant organization which sought the recognition of the Armenian Genocide by the Republic of Turkey, and the establishment of an independent Armenia (including the eastern part of Turkey) from 1975 to 1987. JCAG conducted an international campaign of attacks, mainly in Europe and North America, targeting interests and representatives of Turkey.
Justice Commandos of the Armenian Genocide (JCAG) was the military branch of the Armenian Revolutionary Federation (ARF), a left-wing Armenian nationalist and Pan-Armenian political party established in the 19th century, which at the time of sought the independence of Armenia from the Soviet Union. The ARF was instrumental in the creation of the First Republic of Armenia in 1918, which existed for two years until it was annexed by the Soviet Union, the successor state of the Russian Empire which had previously ruled eastern Armenia. After the Soviets came to power, the ARF leadership was exiled, where the organization maintained its existence internationally through the Armenian diaspora.
The existence of JCAG was discovered in May 1976, when a member was killed by his own bomb in the headquarters of ARF in Paris. It was confirmed when French political scientist Gaïdz Minassian was allowed to consult the archives of ARF for his doctoral thesis. In several occasions, the official newspapers of ARF in the United States, France and Lebanon justified the "armed struggle" and published official communiqués of JCAG. The party had used terrorism many times, both against the Ottoman Empire and Armenians opposed to the ARF, the most famous being Bedros Kapamciyan, mayor of Van, assassinated in December 1912, and archbishop Leon Tourian, assassinated in New York City on December 24, 1933.
