Since the late 1880s, the movement engaged in guerrilla warfare with the Ottoman government and the Kurdish irregulars in the eastern regions of the empire, led by the three Armenian political parties named the Social Democrat Hunchakian Party, the Armenakan Party and the Armenian Revolutionary Federation. Armenians generally saw Russia as their natural ally in the fight against Turks although Russia maintained an oppressive policy in the Caucasus. Only after losing its presence in Europe after the Balkan Wars, the Ottoman government was forced to sign the Armenian reform package in early 1914, however it was disrupted by World War I.
