The Battle of Sirte was the final and most decisive battle of the First Libyan Civil War, beginning when the National Liberation Army attacked the last remnants of the Libyan army still loyal to Muammar Gaddafi in his hometown and designated capital of Sirte, on the Gulf of Sidra. As of September 2011, Sirte and Bani Walid were the last strongholds of Gaddafi loyalists and the National Transitional Council hoped that the fall of Sirte would bring the war to an end. The battle and its aftermath marked the final collapse of the four-decade Gaddafi regime. Both Gaddafi and his son, Mutassim, were wounded and captured, then tortured and killed in custody less than an hour later. The month-long battle left Sirte almost completely in ruins, with many buildings damaged or totally destroyed.

The Libyan civil war or the 2011 Libyan revolution, also known as the First Libyan Civil War was an armed conflict in 2011 in the North African country of Libya that was fought between forces loyal to Colonel Muammar Gaddafi and rebel groups that were seeking to oust his government. The war was preceded by protests in Zawiya on 8 August 2009 and finally ignited by protests in Benghazi beginning on Tuesday, 15 February 2011, which led to clashes with security forces who fired on the crowd. The protests escalated into a rebellion that spread across the country, with the forces opposing Gaddafi establishing an interim governing body, the National Transitional Council.
