SEOUL, South Korea — US President Donald Trump traveled to South Korea for G20 Summit and visited the Demilitarized Zone.
In the wake of World War II -- as the Cold War began -- Korean peninsula was divided along the 38th parallel. The north received Soviet backing, while the United States supported the south.
In 1948 the two sides became officially known as the Democratic People's Republic of Korea (in the north) and the Republic of Korea (in the south).
No formal peace treaty has since been signed, leaving North and South Korea still technically at war.
Here's a videographic illustrating sixty years of conflict in the Korean peninsula.
