The Kim dynasty refers to the ruling family of North Korea, which has been in power since the country's establishment in 1948. The dynasty was founded by Kim Il-sung, who led the country until his death in 1994. His leadership was characterized by a strong emphasis on Juche, a state ideology promoting self-reliance and nationalism. After Kim Il-sung, his son Kim Jong-il took over, continuing the family's authoritarian rule until his death in 2011. The current leader, Kim Jong-un, is the grandson of Kim Il-sung and has maintained the dynasty's tight grip on power, focusing on military development and nuclear capabilities.
