An estimated 300,000 people have been detained or have died in prison since the Syrian uprising broke out. Syrians can be arrested for liking a post on Facebook or for the political activities of a distant relative. They are imprisoned without trial, and tortured and starved, often to death. This book is the first to expose the worst prisons in the Middle East, if not the world. In previous years it had been too dangerous to undertake research on this subject, but the enormous numbers of Syrians taking refuge in neighbouring countries and Europe has allowed unprecedented access to their stories. Based on interviews with both the victims and perpetrators, survivors' memoirs and notes, as well as leaked regime archives, leaked photos, and leaked intelligence files, the book is a testament of the internment and imprisonment system in Syria under the rule of the Assads, father and son (1970-2020). A harrowing account of the machinery of the Assad dynasty, Syrian Gulag is also an urgent expos on Syria today.
