Are Koguryo and Koryo the same concept?

In historical research, Koguryo has vast areas of northeast China and northern Korean Peninsula; South Korea is ruled by the south-central part of the Korean peninsula, and there is little overlap between them.

Koguryo is recorded as Koguryo in history books, or Juli for short. It is an ancient nation living in the northeast of China from 1 century BC to the 7th century BC. In the second year of Emperor Zhao Jian of the Han Dynasty (37 BC), Fuyu Zhu Meng was established in Koguryo County, Xuantu County, Western Han Dynasty (now Xinbin County, Liaoning Province), so it was called Koguryo.

After the 5th century AD, Koguryo was generally referred to as "Korea" for short, and its monarch was also awarded the title of "King of Korea" by Emperor China. However, it should be noted that after 200 years, Dynasty Xian on the Korean Peninsula is not its successor.

In 9 18 AD, the subordinate of Gong, the monarch of Taifeng, revolted and established Wang Jianwei. In 935, Silla was merged, and after the Baekje was destroyed in 936, the "unification of the three Koreas" was realized. The capital of North Korea is Jing Kai (now Kaesong, North Korea).

After 34 generations of monarchs, North Korea became a vassal of continental countries such as the later Tang Dynasty, the later Jin Dynasty, the later Han Dynasty, the later Zhou Dynasty, the Northern Song Dynasty, the Khitan (Liao Dynasty), the Jin Dynasty, Mongolia (Yuan Dynasty) and the Ming Dynasty, and fought with northern nationalities such as Khitan, Jurchen and Mongolia. 1392, Gong was deposed, and the Korean dynasty was established.
