I have limited knowledge about him, but I have looked him up in a few different places.
He created an ethno-state, which is wonderful to the left because he's not white. Turkey was a 2 tier state; Turks and non-Turks.
He was part of The Young Turks (you might know this name from YouTube), who committed the Armenian Genocide. They murdered, through various means, nearly 72% of the Armenians.
He literally added Ataturk to his name and dropped his birth last name. His new last name means Father of the Turks. What a pompous ass.
His middle name was supposedly given to him by his math teacher and means "perfection".
So his name at death is Mustafa - Perfection - Father of the Turks.
