After the Korean Peninsula was partitioned into North and South following its liberation in 1945 from Japanese occupation, Western culture was introduced into South Korea on a small scale with a few Western style bars and clubs playing Western music. After the Korean War, which started on June 25, 1950 and lasted for 3 years, U.S. troops remained in South Korea for protection. With the continued presence of the U.S. military, American and world culture began to infiltrate South Korea. During this time, Western music became more accepted to a wider crowd of young adults.
