Muammar Mohammed Abu Minyar al-Gaddafi (c. 1942 – 20 October 2011), commonly known as Colonel Gaddafi, was a Libyan revolutionary, politician and political theorist. He governed Libya as Revolutionary Chairman of the Libyan Arab Republic from 1969 to 1977 and then as the “Brotherly Leader” of the Great Socialist People’s Libyan Arab Jamahiriya from 1977 to 2011. He was initially ideologically committed to Arab nationalism and Arab socialism but later ruled according to his own Third International Theory. A highly divisive figure, Gaddafi dominated Libya's politics for four decades and was the subject of a pervasive cult of personality. He was decorated with various awards and praised for his anti-imperialist stance, support for Arab—and then African—unity, and for significant improvements that his government brought to the Libyan people's quality of life. Conversely, many Libyans strongly opposed his social and economic reforms, and he was posthumously accused of sexual abuse. He was condemned by many as a dictator whose authoritarian administration violated human rights. Kenya's renowned photojournalist Mohamed Amin, also known as 'Six Camera Mo' captured some of Africa's defining moments and photographed almost every African leader in the 20th century.
