1911 Encyclopædia Britannica/Muras
MURAS, a tribe of South-American Indians living on the Amazon, from the Madeira to the Purus. Formerly a powerful people, they were defeated by their neighbours the Mundrucus in 1788. They are now partly civilized. Each village has a chief whose office is hereditary, but he has little power. The Muras are among the lowest of all Amazonian tribes.
