The Sham Liberation Army (Arabic: جيش تحرير الشام, romanized: Jaysh Tahrir al-Sham), originally called the Sham Liberation Brigade (Arabic: لواء تحرير الشام, romanized: Liwa Tahrir al-Sham), is an armed rebel group active in the Syrian Civil War. It was founded and is led by Firas Bitar, a captain who defected from the Syrian Arab Army in 2012. Until 2016, its sole opponent was the Syrian Armed Forces and its allied militias; it rejected any fighting with the Islamic State of Iraq and the Levant until ISIL attacked its fighters in February 2016.
