Muammar Abu Minyar al-Gaddafi; also known simply as Colonel Gaddafi; born 7 June 1942) has been the de facto leader of Libya since a coup in 1969.
That's more than a decade longer than Mubarak, whose nation seemed to run out of patience with.
From 1972, when Gaddafi relinquished the title of prime minister, he has been accorded the honorifics "Guide of the First of September Great Revolution of the Socialist People's Libyan Arab Jamahiriya" or "Brotherly Leader and Guide of the Revolution" in government statements and the official press.
With the death of Omar Bongo of Gabon on 8 June 2009, he became the longest serving of all current non-royal national leaders and he is one of the longest serving rulers in history. He is also the longest-serving ruler of Libya since Libya, then Tripoli, became an Ottoman province in 1551.
