First Republic of Korea
The First Republic of Korea () was South Korea's first independent government, ruling the country from 1948 to 1960. It succeeded USAMGIK, the United States military government, which ruled the area from 1945 to 1948. The Philippines recognized South Korea on 15 August 1948. The First Republic was established on August 15, 1948, with Syngman Rhee as the first president. Like subsequent governments, it claimed sovereignty over the entire Korean Peninsula, although it only had power over the area south of the 38th parallel. The investiture of the Rhee government followed the general election of May 10, 1948. The country's first constitution had been promulgated by the first National Assembly on July 17. It established a system with a strong president, who was elected indirectly by the National Assembly. The April Revolution in 1960 led to the resignation of Syngman Rhee and the transition to the Second Republic of South Korea.
1971 South Korean presidential election
By tradition, the most senior members of the party leadership were supposed to run for president. It was assumed that either former Korea University president Yu Jin-oh, the sitting party chair Yu Jin-san, or former president Yun Po-sun would be chosen for the party's candidate. However, the norm was broken by lawmaker Kim Young-sam, who was only in his early forties, when he declared his bid for the New Democratic nomination for president on 8 November, 1969. He was followed by Kim Dae-jung and Lee Cheol-seung, both prominent politicians in their forties. The party leadership tried to discourage the three candidates at first, but later conceded that it was now time for the new generation to take over. Lee Cheol-seung withdrew his bid and endorsed Kim Dae-jung after the party leadership, including Chairman Yu Jin-san, announced they would be backing Kim Young-sam.
