Following the Revolution of 14 July 1958, led by Abdul Karim Qassim, which abolished the Hashemite monarchy in Iraq and turned the country into a republic, Iraq adopted a new flag (Law 102 of 1959) that consisted of a black-white-green vertical tricolour, with a red eight-pointed star with a yellow circle at its centre. The black, white, green, and red are the pan-Arab colours, representing pan-Arabism, with the sun of Hammurabi in the middle to represent the ancient heritage of Iraq.
