Proclaiming the nascent organisation as "a new stage in the life of the blessed revolution", Abu Jaber urged all factions of the Syrian opposition to unite under its Islamic leadership and wage a "popular Jihad" to achieve the objectives of the Syrian revolution, which he characterised as the ouster of the Ba'athist regime and Hezbollah militants from Syrian territories, and the formation of an Islamic government.[50] After the announcement, additional groups and individuals joined. The merged group has been primarily led by Jabhat Fatah al-Sham and former Ahrar al-Sham leaders, although the High Command also has representation from other groups.[51] The Nour al-Din al-Zenki Movement[5] split from Tahrir al-Sham in July 2017, and the Ansar al-Din Front in 2018.[52]
The formation of HTS was followed by a string of assassinations of its supporters. In response, HTS launched a successful crackdown on Al-Qaeda loyalists, which cemented its power in Idlib. HTS has since been pursuing a "Syrianization" programme; focused on establishing a stable civilian administration that provides services and connects to humanitarian organizations in addition to maintaining law and order.[49] Tahrir al-Sham's strategy is based on expanding its territorial control in Syria, establishing governance and mobilising popular support. In 2017, HTS permitted Turkish troops to patrol North-West Syria as part of a ceasefire brokered through the Astana negotiations. Its policies have brought it into conflict with Hurras al-Deen, Al-Qaeda's Syrian wing.[53] HTS had an estimated 6,000-15,000 members in 2022.[16]
Hay'at Tahrir al-Sham gives allegiance to the Syrian Salvation Government, which is an alternative government of the Syrian opposition in the Idlib Governorate.[54][55] While the organisation officially adheres to the Salafi school; the High Council of Fatwa of the Syrian Salvation Government - to which it is religiously beholden - consists of ulema from Ash'arite and Sufi traditions as well. In its legal system and educational curriculum, HTS implements Shafi'ite thought and teaches the importance of the four classical Sunnimadhahib (schools of law) in Islamic jurisprudence.[56] As of 2021, HTS is considered the most powerful military faction within the Syrian opposition.[57]

The group has had to open up to local communities and make concessions, especially in the religious sphere. HTS is seeking international acceptance with the development of a strategic partnership with Turkey and desires to open dialogue with Western countries. Overall, HTS has transformed from formerly being a salafi jihadi organisation into having a new mainstream approach to political Islam.{{cite book}}: CS1 maint: location (link) CS1 maint: multiple names: authors list (link)
