Kim Jong Un (born 8 January 1983 or 1984) is a North Korean politician and dictator who has served as supreme leader of North Korea since 2011 and general secretary of the Workers' Party of Korea (WPK) since 2012. He is the third son of Kim Jong Il, who was the second supreme leader, and a grandson of Kim Il Sung, the founder and first supreme leader of North Korea.

From late 2010, Kim was viewed as the successor to the North Korean leadership. Following his father's death in December 2011, state television announced Kim as the "great successor to the revolutionary cause". Kim holds the titles of General Secretary of the Workers' Party of Korea and President of the State Affairs. He is also a member of the Presidium of the WPK Politburo, the highest decision-making body in the country. In July 2012, Kim was promoted to the highest rank of marshal in the Korean People's Army, consolidating his positions as commander-in-chief of the Armed Forces and Chairman of the Central Military Commission. North Korean state media often refer to him as "Respected Comrade Kim Jong Un" or "Marshal Kim Jong Un". He has promoted the policy of byungjin, similar to Kim Il Sung's policy from the 1960s, referring to the simultaneous development of both the economy and the country's nuclear weapons program. He has also revived the structures of the WPK, expanding the party's power at the expense of the military leadership.
