Korea is a peninsula in northeast Asia, Korean Peninsula. Korea became a country (or state) in 918.
In 1948, it split into two countries: North Korea and South Korea. North and South Korea and their allies fought against each other in the Korean War.
People have lived in Korea for about 15,000 years. Korea is known for its fine silk. In the 7th century, the people of China sought after gold-workers from Korea. Europeans had little knowledge about Korea until the modern era.
South Korea has over 50 million people, and North Korea has more than 23 million. South Korea's biggest city is Seoul, the capital of South Korea. The city has more than 10 million people and the region of Seoul has more than 15 million people. North Korea's biggest city is Pyongyang, the capital of North Korea. It has fewer than 4 million people.
Korean people speak the Korean language. Many people in South Korea study English and other languages such as Chinese and Japanese at school.
South Korea is an advanced country with large cities, high-speed rail trains, high-speed internet, and many television and radio networks. Many Korean television dramas are popular around the world. But there are still poor areas, even in South Korea. The Korean farmers are not rich and struggle to compete with cheap food from other countries.
