Ansar al-Sharia (Arabic: أنصار الشريعة‎, lit. 'Partisans of Islamic Law'‎) was a joint operations room of Islamist Syrian rebel factions that operate in Aleppo, Syria. Its stated aim is seizing the city of Aleppo from regime forces in order to administer the city under Sharia law on the basis of a joint charter. In an October 2015 publication, the Washington D.C.-based Institute for the Study of War considered Ansar al-Sharia as one of the "powerbrokers" in Aleppo Province, being primarily "anti-regime" but not necessarily "anti-ISIS". As of late 2015/early 2016 they appear to be defunct.
