Nemesis is not only the name of the Greek goddess of revenge (divine retribution), but was also the code name for an act of human retribution: In a series of covert operations, the Armenian Revolutionary Federation had the Turkish masterminds of the Armenian genocide of 1915-1917, which resulted in the death of more than one million Armenians, assassinated from 1920 to 1922. See the Wikipedia article for details.
To this very day, the Armenian genocide is officially downplayed in Turkey, and Turkey continues to protest the formal recognition of the genocide by other countries. Wikipedia has an in-depth article on the Armenian genocide, one of the tragic events of the 20th century.
The Forty Days of Musa Dagh (1933) by Austrian novelist Franz Werfel (1890-1945) gives a fictional account of the historical events.
