The following is a list of heads of state of North Korea since its foundation in 1948.
History
For most of its existence, North Korea has not specified a formal head of state. The 1948 constitution did not define a head of state, but with regard to political functions usually performed by the head of state, the Chairman of the Standing Committee of the Supreme People’s Assembly (SPA) could be considered one. Kim Il Sung was, at the time, as Premier, merely the head of government but not of state. As his position grew more stable, he wanted to be recognized as the head of state instead. Foreign admirers first started calling him such, and in the 1972 constitution his position was formalized as the President of the republic.
After Kim Il Sung died in 1994, the presidency and hence the position of head of state was left vacant. While the late leader was titled the Eternal President of North Korea, the actual office of the President was written out of the constitution in 1998 making the head of state undefined again. His son and successor, Kim Jong Il, kept official titles given to him by the late president and never formally became the head of state. During this period, the president of the presidium of the SPA exercised many of the functions normally granted to a head of state, such as receiving ambassadors. Titles used by Kim Jong Un have constitutionally defined him as the Supreme Leader, but not formal head of state. However, amendments to the DPRK constitution in 2019 have granted the chairman of the State Affairs Commission (later renamed to president of the State Affairs), a title held by Kim, the status of representing the state and receiving and appointing ambassadors, effectively making him the head of state.
