The Bahrain Thirteen (Arabic: البحرين ثلاثة عشر, romanized: al-Baḥrayn Thalāthat ʻAshar) 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. On 7 January 2013, the defendants lost their last chance of appeal when the Court of Cassation, Bahrain's top court upheld the sentences.
The thirteen are Abdulhadi al-Khawaja, Abdulhadi al-Mukhodher, Abduljalil al-Miqdad, Abduljalil al-Singace, Abdulla al-Mahroos, Abdulwahab Hussain, Hasan Mushaima, Ibrahim Sharif, Mohamed Habib al-Miqdad, Mohamed Hasan Jawad, Mohamed Ismail, Sa’eed al-Nuri and Salah al-Khawaja. They were originally twenty-one, but seven were tried in absentia and one was released in April 2012. The thirteen became popular heroes in Bahrain, and analysts speculated that the government was concerned that their release might re-energize the protest movement and frustrate government supporters who oppose any royal pardons.
The trial, conviction and sentencing of the Bahrain Thirteen drew expressions of concern from European Union, Denmark, France, Ireland, United Kingdom and United States, and international organizations including the United Nations, Amnesty International, Human Rights Watch, Reporters Without Borders, Committee to Protect Journalists and Human Rights First. The government of Bahrain maintained that trials were fair. The Bahrain Independent Commission of Inquiry (BICI), an independent inquiry commissioned by the King of Bahrain, concluded in November 2011 that there had been a discernible pattern of mistreatment to the defendants while in prison.
