Kim Jong-il
In 1974 Kim Il-sung designated Kim Jong-il as his successor, solidifying the leadership transition within North Korea. Kim Jong-il's rise to power was marked by his gradual ascent within the North Korean political hierarchy. He began his official political career in the mid-1970s, holding various positions in the ruling Workers' Party of Korea. Over the years, he consolidated his influence and took on key roles in military and propaganda departments. By 1994, he succeeded his father, Kim Il-sung, as the Supreme Leader of North Korea.
