The Istanbul pogrom, also known as the Istanbul riots, were a series of state-sponsored anti-Greek mob attacks directed primarily at Istanbul's Greek minority on 6–7 September 1955. The pogrom was orchestrated by the governing Democrat Party in Turkey with the cooperation of various security organizations. The events were triggered by the bombing of the Turkish consulate in Thessaloniki, Macedonia, Greece, – the house where Mustafa Kemal Atatürk was born in 1881. The bomb was actually planted by a Turkish usher at the consulate, who was later arrested and confessed. The Turkish press was silent about the arrest, and instead, it insinuated that Greeks had set off the bomb.
