The recorded history of Miryang begins in the Samhan period, when it was known as Mirimidongguk. Due to its strategic location near the Nakdong River, Miryang played an important role from the Silla period forward. It served as an important station on the Great Yeongnam Road during the later Joseon Dynasty, and in the 20th century it became a station on the Gyeongbu Line railroad that connects Busan to Seoul. Miryang remains a key stop along that line, and is now the only city between Busan and Daegu served by KTX express trains.
