Ellen Johnson Sirleaf was born in Monrovia, Liberia. She married in 1955 and, in 1961, travelled with her husband to the US, where she studied economics at Harvard University and other institutions. After her return to Liberia, she worked for the government, including as the Minister of Finance, prior to the military coup of 1980. After having worked within the banking industry and at the United Nations, she was defeated in the Liberian presidential election of 1997. She was later elected as president in 2005, and then re-elected in 2011. Ellen Johnson Sirleaf was the first female head of state ever to be democratically elected in Africa. President Sirleaf was awarded the prestigious Nobel Prize for Peace in 2011. In 2017, former president Sirleaf was awarded the Mo Ibrahim Prize for Achievement in African Leadership, which celebrates excellence in African leadership. The Mo Ibrahim Prize recognises leaders who, during their time in office, have developed their countries, strengthened democracy and human rights for the shared benefit of their people, and advanced sustainable development. Sirleaf was the first female recipient.
