Field Marshal Abd Rabbuh Mansur Al-Hadi (Arabic: عبد ربه منصور الهادي; born 1 September 1945) is a Yemeni politician who is the President of Yemen since 25 February 2012. He was previously the Vice President from 1994 to 2012. Between 4 June and 23 September 2011, he was the Acting President of Yemen while Ali Abdullah Saleh was undergoing medical treatment in Saudi Arabia following an attack on the presidential palace during the 2011 Yemeni uprising. Then, on 23 November, Al-Hadi became Acting President again, after Saleh moved into a non-active role pending the presidential election "in return for immunity from prosecution." Al-Hadi was "expected to form a national unity government and also call for early presidential elections within 90 days" while Saleh continued to serve as President in name only.
He was born on 1 September 1945 in Thakeen village , Al Wade'a District of Abyan. He joined the Army of South Yemen 1970 and became a Major General in early 1990.
He became Vice President of Yemen after Ali Salim Al-Beidh resigned and lost the civil war. Al-Hadi was appointed by President Ali Abdullah Saleh as Vice President on 3 October 1994. Before his appointment as Vice President, he was briefly the Minister of Defense.
Hadi was the sole candidate in the presidential election that was held on 21 February 2012. His candidacy was backed by the ruling party as well as the parliamentary opposition. The Election Commission reported that 65 percent of registered voters in Yemen voted during the election. Abd Rabbuh Mansur Al-Hadi took the oath of office in Yemen's parliament on 25 February 2012. He was formally elected as the president of Yemen on 27 February 2012, when Saleh resigns from presidency and formally ceded power to Hadi.
