Jabhat Ansar al-Din (Arabic: جبهة أنصار الدين, lit. 'Supporters of the Religion Front') is a jihadist alliance that announced itself on 25 July 2014, during the Syrian Civil War. The alliance contains two groups: Harakat Sham al-Islam and Harakat Fajr ash-Sham al-Islamiya; it had declared that was not affiliated with any other "parties". The Green Battalion was originally a signatory, but around October 2014, it swore allegiance to the leader of Jaish al-Muhajireen wal-Ansar and was integrated into that faction. The alliance had attempted to maintain neutrality in the conflict between ISIL and other groups. On 28 January 2017, it joined with numerous other factions to form Tahrir al-Sham, though portions of it left HTS in February 2018.
The groups involved in the coalition have diverse memberships; Harakat Fajr Sham al-Islamiya numbers mostly Syrians from the Aleppo area, while Harakat Sham al-Islam was formed around a core of Moroccan fighters, the Green Battalion mainly had fighters from Saudi Arabia and Jaish al-Mujahireen wal-Ansar was formed by Chechen and other Russian-speaking fighters. On 23 September 2015, Jaish al-Muhajireen wal-Ansar left and joined Jabhat al-Nusra.
