Ruins of Goguryeo in the Hangang River Basin - Goguryeo in the Neighborhood
The Hangang River Basin is a transportation route that crosses the central part of the Korean Peninsula and is a granary that embraces a vast plain. Also, due to its importance as a starting point of transportation to China, it has been the background of varied fortunes of the nation since ancient times.
According to the Records of Baekje section of the Samguk Sagi (History of Three Kingdoms), Baekje had its capital located by the Hangang River Basin from 18 BC to 475 AD in Gongju by the Geumgang River Basin until 538, and in Buyeo until 660 AD, for which the historical period of Baekje is divided into the Hanseong Period, Woongjin Period, and Sabi Period. In 396, King Gwanggaeto of Goguryeo crossed the Arisu river and attacked the royal fortress of Baekje. King Jangsu of Goguryeo attacked Hanseong in 475 and killed King Gaero. According to historical sources, King Seong of Baekje, along with Silla and others, defeated Goguryeo in 551 and was able to capture Hanseong. In other words, from 475 to 551, Goguryeo occupied the Hangang River Basin, which is something we are accustomed to accepting through textbooks. But I wonder if that is really the case.
