Nigerian president who died in office.
Umaru Yar'Adua won the April 2007 presidential election as the candidate of the People's Democratic Party. The election was widely criticized by domestic and international observers for widespread fraud and irregularities, but Yar'Adua was inaugurated on May 29, 2007.
Yar'Adua initiated a presidential amnesty program for militants in the Niger Delta region in June 2009. The program offered disarmament, demobilization, and reintegration in exchange for an end to attacks on oil infrastructure, leading to a significant reduction in violence.
Yar'Adua died on May 5, 2010, after a prolonged illness. His death triggered a constitutional crisis as he had been absent from the country for medical treatment for months, leading to Vice President Goodluck Jonathan assuming acting powers before eventually becoming president.
