tituting the civil war and placing a drastic predicament of political unrest. Pro-Lumumba soldiers invaded northern Katanga, and the UN Congo Command sent troop there to forestall them. Shortly after this event Lumumba was tortured and put to death; taking his place was Joseph-Desire Mobutu. (Lerner, 36)A fragile coalition organized by Tshombe won the parliamentary elections of early 1965, but shortly thereafter Kasavubu ousted Tshombe from the premiership. In late 1965 Mobutu again intervened, installing himself as president in place of Kasavubu. In1966 Mobutu established a presidential form of government; the change was formalized in a new constitution adopted in 1967. (In his first years as president, Mobutu brought political stability to the country, although there were a number of short-lived regionally based revolts, and students occasionally protested his allegedly dictatorial rule.
