Menchú, Rigoberta
Menchú, Rigoberta (1959– ) Guatemalan campaigner for human rights. Menchú was born into a Quiché Maya farming family in the Guatemalan Highlands. Her community was subject to repeated atrocities by the state's security forces because they campaigned for humane working conditions and land rights; in 1979–80 her brother was tortured and mutilated and both her father and mother murdered. In danger of losing her own life, Menchú went into exile in Mexico in 1981 and began to publicize the systematic killing of the Maya people. She helped found the UN working group on the rights of indigenous peoples in 1982 and was awarded the Nobel Peace Prize in 1992.
