Greek and Assyrians have similar genocide claims against (Young) Turks.

"The Hellenic Genocide was the systematic torture, massacre and ethnic cleansing of several millions Hellenes (Greeks) perpetrated by the Turks in Asia Minor, Constantinople (now called Istanbul by the Turks), Eastern Thrace, Imvros, Tenedos, Macedonia, Cappadocia and Pontos.

Most of the victims were massacred between 1895 (much earlier than the World War I) and 1955 (much after the World War II). The present estimate is that some 2.000.000 Greek children, men and women of all ages were killed during that period. "
