President Violeta Chamorro, Presidente de Nicaragua

Violeta Barrios Torres de Chamorro (born October 18, 1929) is a Nicaraguan political leader, former president and publisher. She became president of Nicaragua on April 25, 1990, when she unseated Daniel Ortega. She was elected as the head of a 14-party anti-Sandinista alliance known as the National Opposition Union (Unión Nacional Opositora, UNO), an alliance that ranged from conservatives and liberals to communists. She left office on January 10, 1997. Chamorro was the first and only woman to hold that position in Nicaragua. Chamorro was the first elected female head of state in the Americas, and the second in the Western Hemisphere after Iceland's Vigdís Finnbogadóttir. She was also the second woman elected in her own right as a head of government in the Western Hemisphere (after Eugenia Charles of Dominica), and the first woman in the world to defeat an incumbent president.
