Mahmoud Abbas

Mahmoud Abbas (Arabic: مَحْمُود عَبَّاس‎, Maḥmūd ʿAbbās; born 26 March 1935), also known by the kunya Abu Mazen (Arabic: أَبُو مَازِن‎, 'Abū Māzin), has been the Chairman of the Palestine Liberation Organization (PLO) since 11 November 2004 and became President of the Palestinian National Authority on 15 January 2005 on the Fatah (فتح Fataḥ) ticket.

Elected to serve until 9 January 2009, he unilaterally extended his term for another year and continues in office even after that second deadline expired. Regardless of his titles, Abbas is largely a titular ruler. This is because the only significant geographic region controlled by Palestinians, the Gaza Strip, is controlled by Hamas, Fatah's main rival; in 2009 Hamas announced that it would not recognise the extension or view Abbas as rightful president. Abbas was chosen as the President of the State of Palestine by the Palestine Liberation Organization's Central Council on 23 November 2008, a job he had held unofficially since 8 May 2005.

Abbas served as the first Prime Minister of the Palestinian Authority from March to October 2003 when he resigned citing lack of support from Israel and the United States as well as "internal incitement" against his government. Before being named prime minister, Abbas led the PLO's Negotiations Affairs Department.
