Koguryo's history began in 37 BC and was built by Zhu Meng (also known as King Zou). At first, it was built in Gucheng, Ge Sheng (now Wunvshan City, Huanren Manchu Autonomous County in eastern Liaoning). After the founding of Zhu Meng, the boiling country (in the present Fur River basin) declined. In 32 BC, he sent troops to conquer the southeast of Changbai Mountain (about Cijiang Road in North Korea today). In 28 BC, the northern Japanese colony (now Tumen River Basin) was conquered by force. It began its history with a powerful tribal leader in the northeast (the tribe first became an administrative unit in the county system of the Han Dynasty and eventually developed into a country of one side in the following hundreds of years).
When Wang (Zhu Mengzi, real name) was first attacked by Fuxi and Xianbei, he moved from Gucheng to the inner city (now Ji 'an, Jilin) and began to send troops to invade Liang (now the upper reaches of Taizi River). In 22 AD, he led his troops to attack Fuyu and killed his king Su Dai. More than 1 10,000 Fuxi people will be settled in China in the future. Then in AD 26, through the annexation of Gaima (the so-called country, actually a tribe, in the Wolf Forest Mountain area of present-day North Korea), the king was killed and the land was occupied as a county. The neighboring tea king came to this country in the same year.
In 53 AD, Gong succeeded to the throne (called Taizu or Zu) and captured Dongwoju every two years (also called Nanwoju, in the north-south road of Hamgyong in present-day Korea). Later, it captured a part of Dongshe (now gangwon, Korea) and extended to the Sea of Japan, forcing Fuyu to be called tribute. In order to occupy the densely populated and rich products in Liaodong area, the imperial palace and subsequent kings' expansion to Liaodong area was repeatedly hit by Gongsun, Cao Wei and Murong in the Eastern Han Dynasty, and was on the verge of extinction several times.
In 3 13, Koguryo captured Le Lang County, the territory of the Han Dynasty, but its further development to the south was strongly resisted. In 369, he sent 20,000 troops to invade Baekje and suffered a crushing defeat. In 37 1 year, Baekje sent troops to the north and surrounded Pyongyang. So, the former monarch (named Si You, also known as Zhao) went out of the city and refused to fight, and Zhong Gu died. From the imperial palace to about 200 years ago, the development of Koguryo suffered another setback.
In order to revive the foundation, after Qiu Fu succeeded to the throne, he focused on internal affairs: advocating Buddhism introduced from the Central Plains and unifying his thoughts; Build another school. After more than ten years of governance, the economy has developed and the military strength has increased. In 384, Yilian (the king of the old country) became king, and began to develop outward the following year. Especially after Tan De (An An, known as the King of Guangkai, also known as the King of Tai Hao) ascended the throne, he launched an annexation war against the surrounding ethnic groups and regions. In 427 AD, the 20th generation of Koguryo of Wang Changshou moved to Pyongyang. In present-day North Korea, this is also the reason why South Korea regards Koguryo as its own history.
In the Sui Dynasty, Koguryo gained considerable strength as a separatist regime. Moreover, the alliance with Turkic and other frontier ethnic regimes has seriously threatened the security of the Central Plains. The Sui Dynasty sent troops on three expeditions, but all failed because of Yang Di's fatuous command.
After the death of Tang Xing in Sui Dynasty, Goguryeo continued to occupy Liaodong, the hometown of Yan State, and joined hands with all ethnic groups in the frontier to fight against the Central Plains Dynasty. And constantly to the south of the Korean peninsula Silla country (that is, the predecessor of modern Korea, Wang Jian, who established the king's Korea, that is, Silla people). Silla appealed to the Tang Dynasty for help many times, and Emperor Taizong sent messengers to Koguryo, taking Koguryo's occupation of Liaodong, the original territory of the Central Plains Wang Dynasty, as an example, to persuade Koguryo not to destroy peace in Northeast Asia because of a dispute with Silla over the ownership of a small piece of territory. However, the peaceful efforts of the Tang Dynasty were rejected by the powerful Koguryo minister Gai Suwen. As the co-owner of East Asia, Emperor Taizong invaded Koguryo in 644 AD to protect Silla. The conquest achieved great results, not only recaptured Liaodong, the territory of the Central Plains Dynasty, but also defeated 150,000 reinforcements led by Gao Yanshou in the south of Koguryo in Bishan, outside Anshi. But in the subsequent Anshi siege, Tang Jun spent too much time. In order to avoid the danger of being dragged into winter, Emperor Taizong moved troops. Although this expedition dealt a great blow to Koguryo's separatist regime, Tang Jun also lost thousands of people and more than half of its military forces. Later, the Tang Dynasty maintained its offensive against Koguryo, and in 668 AD (the first year of Li Zhi, Tang Gaozong), Koguryo was destroyed. In the final siege, Silla people also took part in the battle.
The 27th King of Koguryo, King Bao Gao Zang, was captured by the Tang Dynasty. According to Sima Guang's History as a Mirror, Koguryo nobles, most rich families and hundreds of thousands of people were moved to all parts of the Central Plains and integrated into all ethnic groups in China. Others stayed in Liaodong and became subjects of Bohai State, while the others were integrated into Turkic and Silla. Since then, Koguryo has ceased to exist in the world.
On July 1 day, 2004, the 28th session of the World Heritage Committee listed the ancient tombs, murals and noble tombs of Koguryo in North Korea and Northeast China on the World Heritage List.
