Al-Qaeda in the Arabian Peninsula (Arabic: تنظيم القاعدة في جزيرة العرب, translit. Tanẓīm al-Qā‘idah fī Jazīrat al-‘Arab, lit. 'al-Qaeda Organization in the Arabian Peninsula' or تنظيم قاعدة الجهاد في جزيرة العرب, Tanẓīm Qā‘idat al-Jihād fī Jazīrat al-‘Arab, "Organization of Jihad's Base in the Arabian Peninsula"), or AQAP, also known as Ansar al-Sharia in Yemen (Arabic: جماعة أنصار الشريعة, Jamā‘at Anṣār ash-Sharī‘ah, "Group of the Helpers of the Sharia"), is a militant Islamist organization, primarily active in Yemen and Saudi Arabia. It was named for al-Qaeda, and states it is subordinate to that group and its now-deceased leader Osama bin Laden, a Saudi citizen of Yemeni heritage. It is considered the most active of al-Qaeda's branches, or "franchises," that emerged due to weakening central leadership. The U.S government believes AQAP to be the most dangerous al-Qaeda branch. The group established an Emirate during the 2011 Yemeni Revolution.
