Yemeni Revolution
In the wake of the 2011 Yemeni Revolution and the Battle of Zinjibar, an Islamist insurgent organization called Ansar al-Sharia (Yemen) (Supporters of Islamic Law), emerged in Yemen and seized control of areas in the Abyan Governorate and surrounding governorates in southern Yemen and declared them an Islamist Al-Qaeda Emirate in Yemen. There was heavy fighting with the Yemeni security forces over the control of these territories, with Ansar al-Sharia driven out of most of their territory over 2012.
