Kim Jong-il
Kim Jong-il (officially transcribed Kim Jong Il; ; ; 16 February 1941 – 17 December 2011) was the second Supreme Leader of North Korea. He ruled from the death of his father Kim Il-sung, the first Supreme Leader of North Korea, in 1994 until his own death in 2011.

Kim Jong-chul
Kim Jong-chul was born in 1981. He is the son of Kim Jong-il and companion Ko Yong-hui, who died in 2004.
Until 2001, it was assumed that Kim Jong-il's eventual heir would be his eldest son, Kim Jong-nam whose mother was Song Hye-rim. But in May 2001, Kim Jong-nam was arrested at Narita International Airport, Japan, travelling on a forged Dominican Republic passport. He was held and then deported to the People's Republic of China. The incident caused Kim Jong-il to cancel a planned visit to China because of the embarrassment to both countries. As a result of this incident, Kim Jong-nam fell from favour.
