When did idolatry begin again post flood?

Before the flood I remember learning of five prophets who, after their death, were turned into idols and worshipped in place of God. Being that the prophet Noah (Nuh) (peace be upon him) was the only survivor of the flood (assuming a global and not a local flood), and that he was a faithful Nabi (prophet) who spread God's word. Who were the first people to rebel against God and turn towards idolatry in the postdiluvian era?
