The Bahrain Thirteen are thirteen Bahraini opposition leaders, rights activists, bloggers and Shia clerics arrested between 17 March and 9 April 2011 in connection with their role in the national uprising. In June 2011, they were tried by a special military court, the National Safety Court, and convicted of "setting up terror groups to topple the royal regime and change the constitution"; they received sentences ranging from two years to life in prison. A military appeal court upheld the sentences in September. The trial was "one of the most prominent" before the National Safety Court. A retrial in a civilian court was held in April 2012 but the accused were not released from prison. The sentences were upheld again on 4 September 2012.
