Harakat Ahrar al-Sham al-Islamiyya, commonly referred to as Ahrar al-Sham, is a coalition of multiple Islamist and Salafist units that coalesced into a single brigade and later a division in order to fight against the Syrian Government led by Bashar al-Assad during the Syrian Civil War. Ahrar al-Sham was led by Hassan Aboud until his death in 2014. In July 2013, Ahrar al-Sham had 10,000 to 20,000 fighters, which at the time made it the second most powerful unit fighting against al-Assad, after the Free Syrian Army. It was the principal organization operating under the umbrella of the Syrian Islamic Front and was a major component of the Islamic Front. With an estimated 20,000 fighters in 2015, Ahrar al-Sham became the largest rebel group in Syria after the Free Syrian Army became less powerful. Ahrar al-Sham and Jaysh al-Islam are the main rebel groups supported by Turkey. On 18 February 2018, Ahrar al-Sham merged with the Nour al-Din al-Zenki Movement to form the Syrian Liberation Front.

Opposition–ISIL conflict during the Syrian Civil War started after fighting erupted between Syrian opposition groups and the Islamic State of Iraq and the Levant (ISIL). In early January 2014, serious clashes between the groups erupted in the north of the country.

Despite the conflict between ISIL and other rebels, one faction of ISIL has cooperated with the al-Nusra Front and the Green Battalion to combat Hezbollah in the Battle of Qalamoun.
