Kim Il-sung
On 8 July 1994, Kim Il-sung collapsed from a sudden heart attack at the age of 82. After the heart attack, Kim Jong-il ordered the team of doctors who were constantly at his father's side to leave, and arranged for the country's best doctors to be flown in from Pyongyang. After several hours, the doctors from Pyongyang arrived, but despite their efforts to save him, Kim Il-sung died. After the traditional Confucian Mourning period, his death was declared thirty hours later.
