Under the revised constitution, Rhee ran successfully for his third term of office in May 1956. His election for the fourth time, in March 1960, was preceded by a period of tension and violence and was followed by accusations that the election had been fraudulent. Massive student demonstrations took place that culminated in a major event on April 19 in which many demonstrators died. Rhee resigned under pressure six days later and fled to exile in Hawaii, where he died in 1965 at age 90.
