Humala Tasso, Ollanta Moisés, 1962–, Peruvian army officer and political leader, b. Lima. Humala joined the Peruvian army in 1982, became an officer, and during the 1990s commanded troops fighting against Shining Path guerrillas. Later he was accused of human-rights abuses during this period, allegations that he denied. A nationalist and member of the political left, he staged an abortive military rebellion against President Fujimori in 2000. Retiring from the army in 2004, he ran for president in 2006, but lost to Alan García, who narrowly defeated him in the second round. In 2011 he again sought the presidency, having softened his radical image, and narrowly defeated Keiko Fujimori, daughter of the jailed ex-president, in a runoff that was one of Peru's most divisive elections.
