Second South Korean president replaced by Park Chung-hee.
Yun Bo-seon served as Mayor of Seoul from 1949 to 1950, overseeing post-war reconstruction and urban development. He later served as Minister of Commerce and Industry.
Yun Bo-seon was elected president of South Korea in August 1960 after the April Revolution. He led the Second Republic, a parliamentary system, but his presidency was short-lived due to political instability and the 1961 military coup.
Yun Bo-seon was a key opposition figure during the April Revolution that ousted Syngman Rhee. He provided political leadership to the protest movement and later became president as a result of the uprising.
Yun Bo-seon was overthrown by a military coup led by Park Chung-hee on May 16, 1961. He resigned from the presidency, ending the Second Republic and ushering in military rule.
