The timeline of the First Libyan Civil War begins on 15 February 2011 and ends on 20 October 2011. It begins with a series of peaceful protests, similar to others of the Arab Spring, later becoming a full-scale civil war between the forces loyal to Muammar Gaddafi's government and the anti-Gaddafi forces. The conflict can roughly be divided into two periods before and after external military intervention authorized by United Nations Security Council Resolution 1973.
