Operation Nemesis was a covert operation and an assassination campaign by the Armenian Revolutionary Federation (Dashnaktsutyun) carried out between 1920 and 1922, during which a number of former Ottoman political and military figures were assassinated for their role in the Armenian Genocide, as well as Azerbaijani figures for the 1918 massacre of Armenians in Baku. Shahan Natalie and Armen Garo are considered its masterminds. It was named after the Greek goddess of divine retribution, Nemesis.

„May God accept my suffering, for the well-being and prosperity of our nation! Pain upon pain, suffering upon suffering, agony upon agony, wound upon wound in our bodies and in our souls, fall after fall: in this way shall we conquer.“
