Fedayi (Western Armenian: Ֆէտայի Fedayi; Eastern Armenian: Ֆիդայի Fidayi), also known as the Armenian irregular units or Armenian militia, were Armenian civilians who voluntarily left their families to form self-defense units and armed bands in reaction to the mass murder of Armenians and the pillage of Armenian villages by criminals, tribal Kurdish forces, and Hamidian guards during the reign of Abdul Hamid II in late 19th and early 20th centuries, known as the Hamidian massacres. Their ultimate goal was always to gain Armenian autonomy (Armenakans) or independence (Dashnaks, Hunchaks) depending on their ideology and the degree of oppression visited on Armenians.
