The 'Korean War' was fought between 1950 and 1953 on the Korean Peninsula, which
had been divided by the temporary occupations of the Soviet Union and the United
States. The war began on June 25, 1950, when North Korea attacked South Korea.
The war was greatly expanded when the United Nations, led by the United States,
and later Peoples' Republic of China, entered the conflict. The conflict ended
when a cease-fire was reached on July 27, 1953.
The principal support for North Korea came from the People's Republic of China,
with limited assistance from the Soviet Union in forms of combat advisors,
military pilots, and weapons. South Korea was supported by the United Nations
Command forces in Korea (U.N.) forces, consisting primarily of American troops.
Before the conflict, North and South Koreas existed as provisional governments
competing for control over the Korean peninsula after the division of Korea by
the United States and the Soviet Union.
In South Korea, the war is often called '6·25' or '6·25 War' (Korean: 6·25
전쟁), from the date of the start of the conflict or, more formally, Hanguk
Jeonjaeng (Korean: 한국전쟁, literally “Korean War”). In North Korea,
while commonly known as the Korean War, it is formally called the 'Fatherland
Liberation War' (조국해방전쟁). In the United States, the conflict was
officially termed a police action — the 'Korean Conflict' — rather than a
war, largely in order to avoid the necessity of a declaration of war by the U.S.
Congress. The war is sometimes called 'The Forgotten War' because it is a major
conflict of the 20th century that gets far less attention than World War II,
which preceded it, and the controversial Vietnam War, which succeeded
it. In China, the conflict was known as the 'War to Resist America
and Aid Korea' (), but is today commonly called the “Korean War” (, Chaoxian
