Syngman Rhee, the first president of the Republic of (South) Korea, was forced out of office on April 26, 1960 as an aftermath of the April 19 Movement, a student-led uprising. A new government took office on August 13. This was a short-lived period of parliamentary rule in South Korea with a figurehead president, Yun Po-son, in response to the authoritarian excesses and corruption of the Rhee administration. Real power rested with Prime Minister Chang Myon.
