Syrian Civil War

The Army of Conquest (Arabic: جيش الفتح‎‎) or Jaish al-Fatah, abbreviated JaF, was a joint command center of Sunni Islamist Syrian rebel factions participating in the Syrian Civil War.

The alliance was formed in March 2015 under the supervision and coordination of Saudi cleric Dr Abdullah al-Muhaysini. It consists of Islamist rebel factions mainly active in the Idlib Governorate, with some factions active in the Hama and Latakia Governorates. In the course of the following months, it seized most of Idlib Governorate. It is actively supported by the government of Saudi Arabia.

In an October 2015 publication, the Washington D.C.-based Institute for the Study of War considered Jaish al-Fatah as one of the "powerbrokers" in the Idlib, Hama, Daraa and Quneitra Governorates, though not in the Damascus Governorate, and described it as primarily "anti-regime" and "anti-Hezbollah" but not necessarily "anti-ISIS".

At its founding, Jaish al-Fatah contained seven members, three of whom (al-Nusra, Ahrar al-Sham, and Jund al-Aqsa) were directly connected to al-Qaeda or had a similar ideology. With Ahrar al-Sham being the largest group, al-Nusra and Ahrar al-Sham together were reported to represent 90 percent of the troops. Another prominent Islamist faction in the operations room was the Muslim Brotherhood of Syria-linked Sham Legion (Faylaq Al-Sham). Jaish al-Fatah collaborated with more moderate Free Syrian Army factions such as Knights of Justice Brigade.
