Founding president and liberation struggle icon Jomo KENYATTA led Kenya from independence in 1963 until his death in 1978, when Vice President Daniel arap MOI took power in a constitutional succession. The country was a de facto one-party state from 1969 until 1982, after which time the ruling Kenya African National Union (KANU) changed the constitution to make itself the sole legal party in Kenya. MOI acceded to internal and external pressure for political liberalization in late 1991. The ethnically fractured opposition failed to dislodge KANU from power in elections in 1992 and 1997, which were marred by violence and fraud. President MOI stepped down in December 2002 following fair and peaceful elections. Mwai KIBAKI, running as the candidate of the multiethnic, united opposition group, the National Rainbow Coalition (NARC), defeated KANU candidate Uhuru KENYATTA, the son of founding president Jomo KENYATTA, and assumed the presidency following a campaign centered on an anticorruption platform.
KIBAKI's reelection in December 2007 brought charges of vote rigging from Orange Democratic Movement (ODM) candidate Raila ODINGA and unleashed two months of violence in which approximately 1,100 people died. African Union-sponsored mediation led by former UN Secretary General Kofi ANNAN in late February 2008 resulted in a power-sharing accord bringing ODINGA into the government in the restored position of prime minister. The power sharing accord included a broad reform agenda, the centerpiece of which was constitutional reform. In August 2010, Kenyans overwhelmingly adopted a new constitution in a national referendum. The new constitution introduced additional checks and balances to executive power and significant devolution of power and resources to 47 newly created counties. It also eliminated the position of prime minister following the first presidential election under the new constitution, which occurred in March 2013. Uhuru KENYATTA won the election and was sworn into office in April 2013; he began a second term in November 2017.
