Kim Jong-il, birth name Yuri Irsenovich Kim (according to the Soviet Union's records) (, 16 February 1941 – 17 December 2011) was the Supreme Leader of Democratic People's Republic of Korea (North Korea) from the time of his father's death in 1994 until his own death in 2011. He was the son of Kim Il-Sŏng. Official North Korean propaganda said that Jong-il was born on Mount Paektu (a holy mountain in Korea); but most historians think that he was born near Chabarowsk in the Soviet Union. The North Korean laws made him permanent ruler of North Korea for life. He was sometimes referred to as the "Dear Leader", but this was not an official title. His official title was "Chairman of the National Defense Commission of North Korea", "Supreme Commander of the Korean People's Army" and "General Secretary of the Workers' Party of Korea". Many people in North Korea were imprisoned or killed for speaking out against the Kim regime. Almost everyone in North Korea wore a small pin with a picture of Kim Jŏng-Il or Kim Il-Sŏng on it.
