Leymah Roberta Gbowee (born 1 February 1972) is a Liberian peace activist responsible for leading a women's peace movement that helped bring an end to the Second Liberian Civil War in 2003. Her efforts to end the war, along with her collaborator Ellen Johnson Sirleaf, helped usher in a period of peace and enabled a free election in 2005 that Sirleaf won. This made Liberia the first African nation to have a female president.
