Frederick Jacob Titus Chiluba was a Zambian politician who was the second president of Zambia from 1991 to 2002. Chiluba, a trade union leader, won the country's multi-party presidential election in 1991 as the candidate of the Movement for Multi-party Democracy (MMD), defeating long-time President Kenneth Kaunda. He was re-elected in 1996. As he was unable to run for a third term in 2001, former Vice President Levy Mwanawasa instead ran as the MMD candidate and succeeded him. After leaving office, Chiluba was the subject of a long investigation and trial regarding alleged corruption; he was eventually acquitted in 2009.
