TUNIS — The Truth and Dignity Commission of Tunisia released its final report this week on more than 50 years of dictatorship in the country, a devastating, 2,000-page archive of torture and human rights violations that is intended to prevent the return of authoritarian rule.

The president of the commission, Sihem Bensedrine, unveiled the document at a ceremony in Tunis on Tuesday and posted the entire Arabic-language document on the commission’s website.

The report is the product of four and a half years of investigation by the commission, which was mandated by a Constitutional Assembly after Tunisia’s popular uprising of 2010 and 2011. That revolution inspired Arab Spring revolts across North Africa and the Middle East — most of which were followed by violent crackdowns and power struggles, if not civil war.

After the revolution in Tunisia, however, leaders sought to prevent a backslide to authoritarianism, creating the commission to unveil the truth of crimes in the country from 1955 to 2013, preserve the evidence for public memory and recommend cases for prosecution.
