Editing Lelang Commandery (section)

===Jin dynasty===
Lelang was then inherited by the Jin dynasty. Due to bitter civil wars, Jin was unable to control its holdings within the northern section of the Korean peninsula at the beginning of the 4th century and was no longer able to dispatch officials to the frontier commanderies, which were maintained by the dwindling local population of remaining Han Chinese residents. The ''[[Zizhi Tongjian]]'' states that Zhang Tong (張統) of Liaodong, Wang Zun (王遵) of Lelang and over one thousand households decided to break away from Jin and submit to the [[Xianbei]] warlord of [[Former Yan]] [[Murong Hui]]. Murong Hui relocated the remnants of the commandery to the west within Liaodong. [[Goguryeo]] annexed the former territory of Lelang in 313. Goguryeo ended Chinese rule over any part of the Korean peninsula by conquering [[Lelang]] in 313. After Lelang's fall, some commandery residents may have fled south to the indigenous Han polities there, bringing with them their culture that spread to the southern part of the Korean peninsula. With the collapse of the commanderies after four centuries of Chinese rule, Goguryeo and the native polities in the south that became [[Baekje]] and [[Silla]] began to grow and develop rapidly, heavily influenced by the culture of the [[Four Commanderies of Han]].<ref>Kwon, O-Jung.

Goguryeo absorbed much of what was left of Lelang through its infrastructure, economy, local inhabitants, and advanced culture. Unable to govern the region directly and form a new political center immediately, Goguryeo began to consolidate authority by replacing previous government administrators with its own appointed officials, mostly refugees and exiles from China, the most famous being Dong Shou (冬壽) who was entombed at [[Anak Tomb No. 3]], overtly retaining the previous administrative system of Lelang. In 334 Goguryeo established the fortress and city of Pyongyang-song within the center of the former commandery. Towards the end of the 4th century, in order to focus on the growing threat of [[Baekje]] and having checked the power of [[Former Yan]] in Liaodong, Goguryeo began to actively strengthen and govern the city. In 427 Goguryeo moved its capital to [[Pyongyang]] from its former capital of [[Ji'an, Jilin|Ji'an]] as the new political center of the kingdom in order to administer its territories more effectively.<ref>Yeo, Hokyu.
