Background: A violent Marxist urban guerrilla movement, the Tupamaros, launched in the late 1960s, led Uruguay's president to agree to military control of his administration in 1973. By the end of the year the rebels had been crushed, but the military continued to expand its hold throughout the government. Civilian rule was not restored until 1985. Uruguay has long had one of South America's highest standards of living; its political and labor conditions are among the freest on the continent.
