Ethno-religious composition of Syria immediately before the civil war in 2011
The Syrian Civil War has been described as an "intensely sectarian conflict". The focus of the conflict has been identified as a ruling minority Alawite government (with Alawites being a largely syncretic Shiite Muslim offshoot from which President Assad's most senior political and military associates are drawn) and allied Shi'a governments such as Iran, pitted against the country's Sunni Muslim majority who are aligned with the Syrian opposition and their Sunni Turkish and Persian Gulf State backers. The conflict had drawn in other ethno-religious minorities, including Armenians, Assyrians, Druze, Palestinians, Kurds, Yazidi, Mhallami, Arab Christians, Mandaeans, Turkmens and Greeks.
In 2012 the first Christian Free Syrian Army unit formed, yet it was reported that the Assad government still had the support of the majority of the country's Christians of various ethnicities and denominations. By 2013 an increasing number of Christians favored the opposition. In 2014, the predominantly Christian Syriac Military Council formed an alliance with the FSA, and other Syrian Christian militias such as the Sutoro had joined the Syrian opposition against the government.
The Alawite sect of Islam has the second highest religious following in the Syrian Arab Republic and remains at the heart of the Syrian Government grassroot support, however in April 2016 Alawite leaders released a document seeking to distance themselves from both Assad and Shia Islam. Incidents of sectarianism amongst the Sunni population have been said to be rooted in that both Hafez al-Assad and Bashar al-Assad are Alawites, a minority fundamentalist Sunnis see as heretics. Additionally, the Syrian government maintains a network known as the shabiha, a shadow militia that anti-government activists allege are prepared to use force, violence, weapons and racketeering, whose members primarily consist of Alawites. Iranian provides training and equipping of Shia militants from Lebanon, Iraq, Syria, and Afghanistan to fight with various sectarian Sunni militias in Syria, as well as alleged Syrian Government coordination with the Houthi of Yemen. Minorities such as the Druze and Ismailis have refused to join these militias or be associated with the government, with even some Alawites and Christians who are openly pro-government also refusing to join these militias or serve their conscription terms.
