The background of the battle of Dylan store

After Wang Jian established the Korean regime in 9 18, he actively expanded his territory to the north. In 922, the ancient capital, Pyongyang, was renovated, relocated and set up an official office, commensurate with Xijing, and continued to expand northward based on Xijing. In 926, the Liao Dynasty destroyed the Bohai State and then moved to the western part of the original Bohai State on the Korean Peninsula, weakening the power of the Liao Dynasty here. North Korea lured and repelled the Bohai people here and the Jurchen nationality under the former Bohai rule, and constantly expanded its power. For this reason, there were contradictions, disputes and even conflicts with Liao (see Liao-Han War). 1044, North Korea built the Great Wall between the south of Hamgyong and the north of Yongxing on the Korean Peninsula, reaching Lianpu, and built Dingzhou, Xuande and Yuanxing three passes (all in South Hamgyong Road of North Korea). Since then, Liao and Northeast Korea are bounded by the Great Wall and Sanguan. In Liao Dynasty, "North Korea extended the northern boundary of its territory from Bajiang (now Datong River) in Silla to Qingchuan River Basin", bordering on 30 ethnic groups such as Nuzhen in Changbai Mountain and Nuzhen in Yalu River, who lived in the northern part of the peninsula for a long time.

The 30 Nuzhen people in Changbai Mountain originated in Baishan before Sui Dynasty. During the Tang and Liao dynasties, although some Jurchen entered the south, the main body of this department did not change much. By the Liao Dynasty, this jurchen was "distributed in Yanbian area, south of Tonghua area, south of Tumen River, north and south of Korea, Liangjiang Road and Cijiang Road, that is, Xianxing Plain area". In the first year of Emperor Taizong of Liao Dynasty (10 12), "Thirty straight women from Changbai Mountain came to pay tribute to [Liao] and beg for knighthood". In the same year, "Nuzhen Chief Ma led 30 tribal children to [North Korea] to offer local horses". In the latter quotation, the "30 tribes" of Nuzhen refer to 30 Nuzhen in Changbai Mountain. These two historical materials seem to show that the Nuzhen in Changbai Mountain developed into 30 in 10 12, forming a tribal alliance and actively contacting with the outside world. The History of Korea also lists the names of thirty books. This history book also calls this jurchen Oriental Jurchen, Oriental Fan and Northeast Jurchen. Obviously, it starts from the region, takes Korea as the center, and calls by direction. Thirty Nuzhen people in Changbai Mountain belong to one of the "Ten Exterior Areas" in Liao Dynasty, where the Nuzhen Palace in Changbai Mountain was established. At the same time, there are some dependencies with South Korea.

These two Nuzhen in Liao Dynasty, especially the thirty Nuzhen in Changbai Mountain, had frequent contacts with North Korea. Horse, mink, green rat skin, armored shoes, arrows, rice, etc. It is often shipped to North Korea in the form of "tribute", and textiles, cattle and utensils are shipped back from North Korea in exchange for needed goods. Korea made the Nuzhen chieftain of this department a knight, such as Daxiang, Daxie, Fuzheng, General and other military commanders, as a sign of softening the network. At the same time, this Jurchen often has conflicts with North Korea on land and at sea.

Nvzhen is an ancient ethnic group in the northeast of China, living in the northeast and the northern part of the Korean Peninsula. Among the more than 30 tribes of Jurchen, the alliance of Jurchen headed by Wanyan Department has gradually grown and unified all the departments of Jurchen. Through the continuous efforts of Jing, Shi and Su, the Nuzhen of Tumen River has been incorporated into the alliance. With the unification and expansion of the Jurchen tribal alliance, the conflict with North Korea focused on the struggle for Lashio Temple. There are many Nuzhen tribes living in Dalandian (now the Motianling area north of Hamgyong, South Hamgyong Province, North Korea), which is adjacent to Wang's Koryo. When I was in Ugunai, I was associated with the Virgin Tribal Alliance, and some jurchen have expressed their willingness to join the Virgin Tribal Alliance. When Kang Zong recruited an, he "sent stones to lead troops and the stars (now Buerhatong River) and Tongmen (now Tumen River) to B- Li to help recruit soldiers to live in Nishui (now near the bright red plain) and to gather seven cities in rebellion." But South Korea is afraid that they will join the party. "It is not good to be close to yourself, so I will ask people to stop." As a result, the battle between Jurchen and North Korea for lazy land began. Mu Zong Ying Ge sent a special envoy to North Korea in 002+065438+, and a war for lazy land soon broke out. 36806.88686886666
