Han River
In Korean history, Han river played a central role.  The rise and fall of the nation depended on taking the Han river. Especially in three kingdom period, there were fierce struggles to take the Han river. Baekje was the first to take the Han river. They recognized it as a primary waterway that links the central western region of the peninsula with the Yellow Sea. The kingdom of Goguryeo took the Han river during the reign of its King Jangsu. In 553, Silla broke its alliance with Baekje and took the control of the entire river.
