Answer:
The Kim dynasty is a family of leaders who have ruled North Korea since its inception in 1948. The founder of the dynasty was Kim Il-sung, who served as the country's first premier and later as its president. He was succeeded by his son, Kim Jong-il, who ruled for 17 years until his death in 2011. Kim Jong-il was then succeeded by his own son, Kim Jong-un, who has been the country's supreme leader since 2011. The Kim family has maintained a tight grip on power through a cult of personality and repressive policies, while pursuing nuclear weapons and missiles programs that have led to international isolation and sanctions.
