Korea is a long land in East Asia split into North and South, and it matters because it affects people’s lives and world events.
Korea is a place in East Asia that includes the long Korean Peninsula, the island of Jeju, and many small islands, and the peninsula is divided into North Korea and South Korea near the middle.
The peninsula was split along the 38th parallel and two separate countries formed in 1948, and then the Korean War happened from 1950 to 1953; fighting stopped with an armistice in 1953 but no peace treaty was signed.
People have lived there for tens of thousands of years, and by about 10,000 BCE they made pottery and in the Neolithic lived in small villages, grew plants, and made tools from stone and bone.
Long ago Korea had three kingdoms called Goguryeo, Baekje, and Silla; Goguryeo ruled the north, Baekje was a sea power in the southwest, and Silla controlled the southeast and later united much of Korea with help from Tang China.
The Korean Demilitarized Zone is a buffer along the old dividing line that people mostly left alone, so forests and wetlands grew there and now help many animals and protect habitats for about 82 endangered species.
Korean is the main language, spoken by about 80 million people worldwide (about 50 million in South Korea and 25 million in North Korea), and people usually write with the alphabet Hangul, which was created in the 15th century.
