Kim Il Sung, the first and "eternal" president of North Korea, took power in 1948 with the support of the Soviet Union. The official calendar in North Korea begins with his birth year, 1912, designating it "Juche 1" after the state's Juche ideology. He was 41 when, as shown here, he signed the 1953 armistice that effectively ended the Korean War.

In the years and decades after the war, Pyongyang's propaganda machine worked hard to weave a mythical narrative around Kim Il Sung. His childhood and the time he spent fighting Japanese troops in the 1930s were embellished to portray him as an unrivaled military and political genius. At the 1980 party congress, Kim announced he would be succeeded by his son, Kim Jong Il.

In 1992, Kim Il Sung started writing and publishing his memoirs, entitled "Reminiscences: With the Century." Describing his childhood, the North Korean leader claims that he first joined an anti-Japanese rally at 6 years old and became involved with the independence struggle at 8. The memoirs remained unfinished at Kim Il Sung's death in 1994.

After spending years in the top tiers of the regime, Kim Jong Il took power after his father's death. Kim Jong Il's 16-year rule was marked by famine and economic crisis in an already impoverished country. However, the cult of personality surrounding him and his father, Kim Il Sung, grew even stronger.

Historians outside North Korea believe Kim Jong Il was born in a military camp in eastern Russia, most likely in 1941. However, the leader's official biography claims it happened on the sacred Korean mountain Paektu, exactly 30 years after his father, on April 15, 1942. A North Korean legend says the birth was blessed by a new star and a double rainbow.

Kim Jong Il had three sons and two daughters with three different women. This 1981 photo shows Kim Jong Il sitting besides his son Kim Jong Nam, with his sister-in-law and her two children in the background. Kim Jong Nam was eventually assassinated in 2017.

In 2009, Western media reported that Kim Jong Il had picked his youngest son, Kim Jong Un, to take over as the head of the regime. The two appeared together at a military parade on 2010, a year before Kim Jong Il passed away.

According to Pyongyang, the death of Kim Jong Il in 2011 was marked by a series of mysterious events. State media reported that ice snapped loudly at a lake on the Paektu mountain during a sudden snowstorm, with a glowing message appearing on the rocks. After Kim Jong Il's death, a 22-meter (72-foot) statue of him was erected next to the one of his father (l.) in Pyongyang.

Kim Jong Un mostly stayed out of the spotlight before his ascent to power. His exact age is disputed, but he is believed to have been born between 1982 and 1984. He was reportedly educated in Switzerland. In 2013, he surprised the world by meeting with former NBA star Dennis Rodman in Pyongyang.

Like the leaders before him, Kim Jong Un is hallowed by the state's totalitarian regime. In 2015, South Korean media reported about a new teacher's manual in the North that claimed Kim Jong Un could drive at the age of 3. In 2017, state media said that a monument to the young leader would be build on Mount Paektu.

Altough Kim took power at a younger age and with less of a public profile than his father and grandfather, he has managed to maintain his grip on power. The assassination of his half-brother Kim Jong Nam in 2017 served to cement his reputation abroad as a merciless dictator. The North Korean leader has also vastly expanded the country's nuclear arsenal.

In August 2017, the UN Security Council adopted a resolution banning all coal, iron, iron ore and lead imports from North Korea. Pictured here is China's Liaoning Greenland Energy Coal Co. in Dandong, on the border with North Korea.

North Korea is prohibited from opening banks abroad, and UN member states are prohibited from operating financial institutions on Pyongyang's behalf. Any dealings that might help North Korea skirt the sanctions are banned, and UN member states must expel and repatriate anyone working on the regime's financial behalf.

This North Korean cargo ship found itself boarded for inspection in the Philippines in March 2016 after the United Nations ordered member nations to de-register any vessel owned, operated or crewed on orders from Pyongyang. North Korean ships also cannot fly the flags of other nations to evade sanctions.

Air Koryo, North Korea's national carrier, remains exempt from aviation sanctions and still has scheduled flights to China and Russia, as well as several domestic routes. However, the airline cannot fly to the European Union, which has banned it on safety grounds, and the United States prevents citizens from legally conducting business with the carrier.

In December 2017, a new raft of UN sanctions targeted fuel imports in North Korea, meaning its residents could have difficulties driving the country in Pyeonghwa sedans (pictured above). The sale and transfer of diesel and kerosene are limited while the import of crude oil is capped at 4 million barrels a year.

UN sanctions limit North Korea's diplomats abroad — at the country's Berlin embassy, for example — to only one bank account each. North Korea is also not permitted to own real estate abroad for any purposes other than consular.

It's a safe bet that North Korea's marching military did not learn its moves abroad: UN sanctions ban foreign security forces from training the country's army, police or paramilitary units. The United Nations does permit medical exchanges, but otherwise allow very little assistance of scientific or technical value.

Anyone wanting to own a larger-than-life Kim will have to await the end of North Korea's nuclear program. The UN sanctions currently ban the sale of statues by the nation.
