Who is the supreme leader of North Korea? And what history lead to his rule?
The current supreme leader of North Korea is Kim Jong-un. He has been in power since December 2011, following the death of his father, Kim Jong-il, who was the previous leader of North Korea.

Kim Jong-un is the third generation of the Kim family to rule North Korea. His grandfather, Kim Il-sung, was the founding leader of North Korea and ruled the country from its inception in 1948 until his death in 1994. Kim Il-sung's son, Kim Jong-il, then took over as leader and ruled until his death in 2011.

Kim Jong-un was designated as the successor to Kim Jong-il several years before his father's death, and after his father's death, he was quickly appointed as the supreme leader. Kim Jong-un has continued his family's legacy of authoritarian rule, maintaining tight control over the country's political and economic systems and continuing to pursue a nuclear weapons program.

The history of North Korea's ruling family dates back to the country's formation after World War II, when Kim Il-sung established a socialist state in the northern part of the Korean peninsula. The Kim family's rule has been marked by a cult of personality around the leaders, strict control over the media and public expression, and a focus on military development and self-reliance.
