Syrian Salvation Government
The Syrian Salvation Government (SSG) was a de facto unrecognized quasi-state in Syria formed on 2 November 2017 by Hay'at Tahrir al-Sham (HTS) and other opposition groups during the Syrian civil war. It controlled some of northwest Syria, namely parts of the Idlib and Aleppo Governorate and smaller parts of the Hama and Latakia Governorate.
