The League of Armenian Social Democrats (Armenian: Հայ Սոցիալ-Դեմոկրատների Միություն, Armenian: Hay Sotsial-Demokratneri Miut'yun, abbreviated ՀՍԴՄ, HSDM) was the first Armenian Iskraist social democratic organization.
The League of Armenian Social Democrats was founded in Tiflis in 1902 by Stepan Shahumyan, Melik Melikian, Achot Khoumerian, Assadour Kakhoyan, B. Knunyantsi and Arshak Zubarian.[1] In October 1902, it published its manifesto, which adhered to proletarian internationalism. Lenin hailed the positions of HSDM on the national question, but criticized its federalist demands.[1] HSDM published the newspaper Proletaryat.[2] In March 1903, HSDM merged into the Caucasus Organization of the Russian Social Democratic Labour Party.[1]
