The party was active during and after the Armenian Genocide when the Armenians began mobilising politically for rights under the oppressing Ottoman regime. A main figure in the Ramgavar party, Diran Pasha, led the resistance within the Ottoman political arena and subsequently picked up arms when the Ottoman government began the systematic annihilation of the Armenian population in Anatolia and Northeastern Turkey (Western Armenia). With his band of brothers, Zinvadz Lerner, Diran Pasha held out the Ottoman forces from the ancient castle at Haghardzin village. The siege concluded with the death of Diran and all his men.
