Kim Tu-bong
Party control increased throughout the country after the congress. From 27–30 March 1948, the WPNK convened its 2nd Congress. While Kim Tu-bong was still the party's formal head, Kim Il-sung presented the main report to the congress. In it he claimed that North Korea was "a base of democracy", in contrast to South Korea (which was, he believed, dictatorial). On 28 April 1948 a special session of the Supreme People's Assembly approved the constitution (proposed and written by WPNK cadres), which led to the official establishment of an independent North Korea. It did not call for the establishment of an independent North Korea, but for a unified (communist) Korea; the capital of the Democratic People's Republic of Korea (DPRK) would be Seoul, not Pyongyang. Kim Il-sung was the appointed head of government of the new state, with Kim Tu-bong heading the legislative branch. A year later on 24 June 1949, the Workers' Party of Korea was created with the merger of the WPNK and the Workers' Party of South Korea.
