PYONGYANG, North Korea — Even as the world changed around him, North Korean leader Kim Jong Il remained firmly in control, ruling absolutely at home and keeping the rest of the world on edge through a nuclear weapons program.
Inheriting power from his father, he led his nation through a devastating famine while frustrating the U.S. and other global powers with an on-again, off-again approach to talks on giving up nuclear arms in return for food and other assistance. Kim was one of the last remnants of a Cold War-era that ended years earlier in most other countries.
His death after 17 years as leader was announced Monday by state television two days after he died. North Korea's news agency reported that he had died at 8:30 a.m. Saturday after having a heart attack on a train, adding that he had been treated for cardiac and cerebrovascular diseases for a long time. He was 69.
He is widely expected to be succeeded by his third son in a nation that celebrates the ruling family with an intense cult of personality. On Monday, the North Korean news agency dubbed the younger Kim a "great successor" as the country rallied around him as the next leader.
Kim's longtime pursuit of nuclear weapons and his military's repeated threats to South Korea and the U.S. have stoked fears that war might again break out or that North Korea might provide weapons of mass destruction to terrorist movements.
South Korea put its military on "high alert" and President Lee Myung-bak convened a national security council meeting after the news of Kim's death. The Korean peninsula remains technically in a state of war more than 50 years after the Cold War-era armed conflict ended in a cease-fire.
Kim is believed to have suffered a stroke in 2008 but he had appeared relatively vigorous in photos and video from recent trips to China and Russia and in numerous trips around the country carefully documented by state media.
Kim Jong Il took power after his father, revered North Korean founder Kim Il Sung, died in 1994. He had been groomed for 20 years to lead the communist nation founded by his guerrilla fighter-turned-politician father and built according to the principle of "juche," or self-reliance.
In September 2010, Kim Jong Il unveiled his third son, the twenty-something Kim Jong Un, as his successor, putting him in high-ranking posts. In recent months, he had accompanied his father on trips around the country, another sign that he was being groomed to take over.
Few firm facts are available when it comes to North Korea, one of the most isolated countries in the world, and not much is clear about the man known as the "Dear Leader."
North Korean legend has it that Kim was born on Mount Paektu, one of Korea's most cherished sites, in 1942, a birth heralded in the heavens by a pair of rainbows and a brilliant new star. Soviet records, however, indicate he was born in Siberia, in 1941.
Kim Il Sung, who for years fought for independence from Korea's colonial ruler, Japan, from a base in Russia, emerged as a communist leader after returning to Korea in 1945 after Japan was defeated in World War II.
With the peninsula divided between the Soviet-administered north and the U.S.-administered south, Kim rose to power as North Korea's first leader in 1948 while Syngman Rhee became South Korea's first president.
The North invaded the South in 1950, sparking a war that would last three years, kill millions of civilians and leave the peninsula divided by a Demilitarized Zone that today remains one of the world's most heavily fortified.
In the North, Kim Il Sung meshed Stalinist ideology with a cult of personality that encompassed him and his son. Their portraits hang in every building in North Korea and on the lapels of every dutiful North Korean.
