Northern Wei in the context of "Chuge"

The Sixteen Kingdoms (simplified Chinese: 十六国; traditional Chinese: 十六國; pinyin: Shíliù Guó), less commonly the Sixteen States, was a chaotic period in Chinese history from AD 304 to 439 when northern China fragmented into a series of short-lived dynastic states. Most of these regimes were created by groups such as the Xiongnu, Xianbei, Di, Jie, and Qiang, who had moved into northern and western China over earlier centuries and rose in rebellion against the Western Jin dynasty in the early fourth century. Some states were founded by the Han as well. Regardless of their rulers' background, every state adopted dynastic institutions in the Han tradition and styled itself as a legitimate monarchy. These states often fought one another and also contended with the Eastern Jin dynasty, which governed the south after the collapse of Western Jin in 317. The era ended in 439, when Northern Wei, founded by the Tuoba clan of the Xianbei, reunified the north. The Eastern Jin dynasty had already collapsed in 420 and been replaced by the Liu Song dynasty, the first of the Southern Dynasties. After the consolidation of the north, Chinese history entered the period known as the Northern and Southern Dynasties.

The term "Sixteen Kingdoms" was first used by the 6th-century historian Cui Hong in the Spring and Autumn Annals of the Sixteen Kingdoms and refers to the five Liangs (Former, Later, Northern, Southern and Western), four Yans (Former, Later, Northern, and Southern), three Qins (Former, Later and Western), two Zhaos (Han/Former and Later), Cheng-Han and Xia. Cui Hong did not count several other kingdoms that appeared at the time including the Ran Wei, Zhai Wei, Chouchi, Duan Qi, Qiao Shu, Huan Chu, Tuyuhun and Western Yan. Nor did he include the Northern Wei and its predecessor Dai, because the Northern Wei is considered to be the first of the Northern Dynasties in the period that followed the Sixteen Kingdoms.

The equal-field system (Chinese: 均田制度; pinyin: Jūntián Zhìdù) or land-equalization system was a system of land ownership and distribution in China used from the Northern Wei dynasty to the mid-Tang dynasty.

By the Han dynasty, the well-field system of land distribution had fallen out of use in China though reformers like Wang Mang tried to restore it. The equal-field system was introduced into practice around 485 AD by the Emperor Xiaowen of Northern Wei under the support of Empress Dowager Feng during the Northern and Southern dynasties period. The system was eventually adopted by other regimes, and its use continued into the Sui and Tang dynasties.During the Northern Wei dynasty, the government implemented the equal-field system (jūntián zhì, 均田制) in conjunction with the Three Elders system (sānzhǎng zhì, 三长制). This policy weakened the power of local hereditary aristocratic clans (shìjiā ménfá, 世家门阀), curtailed widespread land annexation, and strengthened the emerging landlord class based on self-cultivating farmers (zìgēng nóng, 自耕农).

Shiwei (simplified Chinese: 室韦; traditional Chinese: 室韋; pinyin: Shìwéi; Wade–Giles: Shih-wei) were a Mongolic people that inhabited far-eastern Mongolia, northern Inner Mongolia, northern Manchuria and the area near the Okhotsk Sea beach. Records mentioning the Shiwei were recorded from the time of the Northern Wei (386–534) until the rise of the Mongols under Genghis Khan in 1206 when the name "Mongol" and "Tatar" were applied to all the Shiwei tribes.

The Shiwei-Mongols were closely related to the Khitan people to their south. As a result of pressure from the west, south and south-east they never established unified, semi-sedentarized empires like their neighbors, but remained nomadic confederations led by tribal chieftains, alternately submitting to the Turks, the Chinese and the Khitan as the political climate changed. The Mengwu Shiwei, one of the 20 Shiwei tribes during the Tang dynasty (618–907), were also called the Menggu during the Liao dynasty (907–1125) and are generally considered to be the ancestors of the Mongols of Genghis Khan. The modern Korean pronunciation of Mengwu (蒙兀 Měngwù) is Mong-ol (/moŋ.ol/). Mongolia is still called "Menggu" (蒙古 Měnggǔ) in Chinese today.

The Book of Wei, also known by its Chinese name as the Wei Shu, is a classic Chinese historical text compiled by Wei Shou from 551 to 554, and is an important text describing the history of the Northern Wei and Eastern Wei from 386 to 550. Widely regarded as the official and authoritative source historical text for that period, it is one of the Twenty-Four Histories.

Bodhiruci (Chinese: 菩提流支; pinyin: pú tí liú zhī) was a Buddhist monk from North India (6th century CE) active in the area of Luoyang, China. He was appointed as master translator at Yongning (永寧寺) temple by emperor Xuanwu of the Northern Wei. In his translations, Bodhiruci was assisted by the central Indian monk Ratnamati (勒那摩提).

Bodhiruci translated various important texts including the Ten Stages Sutra (Chinese: 十地経論) and the commentary on this sutra by Vasubandhu (Shidi jing lun 十地經論). He translated the Sukhāvatīvyūha Sūtra as well as Vasubandhu's commentary titled Stanzas of the vow to be reborn [in the Pure Land] in the Sūtra [of the Buddha] Infinite Life (Wuliangshou jing youbotishe yuansheng jie 無量壽經優波提 舍願生偈). He also translated Sūtra of the descent to Laṅka (Ru lengqie jing 入楞伽經), and a Sūtra of Buddha names (Foming jing 佛名經).

Wei (/weɪ/), known in historiography as the Western Wei (Chinese: 西魏; pinyin: Xī Wèi), was an imperial dynasty of China that followed the disintegration of the Northern Wei. One of the Northern dynasties during the era of the Northern and Southern dynasties, it ruled the western part of northern China from 535 to 557. As with the Northern Wei dynasty that preceded it, the ruling family of the Western Wei were members of the Tuoba clan of the Xianbei.

Liaodong Commandery (Chinese: 遼東郡) was a commandery in imperial China that existed from the Warring States period to the Northern dynasties. It was located in modern Liaoning, to the east of the Liao River.

The commandery was created by the state of Yan on its northern border during the Warring States period. In Western Han dynasty, It administered 18 counties, including Xiangping (襄平), Xinchang (新昌), Wulü (無慮), Wangping (望平), Fang (房), Houcheng (候城), Liaodui (遼隊), Liaoyang (遼陽), Xiandu (險瀆), Jujiu (居就), Gaoxian (高顯), Anshi (安市), Wuci (武次), Pingguo (平郭), Xi'anping (西安平), Wen (文), Fanhan (番汗), and Dashi (沓氏). In 2 AD, the population was 272,539, in 55,972 households. In Eastern Han, 11 counties remained, including Xiangping, Xinchang, Wulü, Wangping, Houcheng, Anshi, Pingguo, Xi'anshi, Wen, Fanhan and Dashi. In 140 AD, the population was 64,158 households. During the reign of Emperor Xian, management of Buyeo affairs was transferred from Xuantu Commandery to Liaodong. In the Cao Wei dynasty, Xiangping in Liaodong became the seat of an office known as the "Colonel of the Dongyi" (東夷校尉), which was in charge of the military and relationships with the local peoples. In early Western Jin, the territory became the Liaodong Principality (遼東國). In 280 AD, the commandery had 8 counties, and a population of 5,400 households. A number of new commanderies was established in the region throughout the Sixteen Kingdoms and Northern dynasties periods, and by the time of Northern Wei, Liaodong only consisted of 2 counties, namely Xiangping and Xinchang. It was eventually dissolved during Northern Qi.

The Western Thousand Buddha Caves (Chinese: 西千佛洞; pinyin: Xī Qiānfó Dòng) is a Buddhist cave temple site in Dunhuang, Gansu Province, China. The site is located approximately 35 km southwest of the urban centre and about the same distance from the Yangguan Pass; the area served as a staging post for travellers on the Silk Road. It is the western counterpart of the Mogao Caves, also known as the "Caves of the Thousand Buddhas" after the founding monk Yuezun's vision in 366 of "golden radiance in the form of a thousand Buddhas". The caves were excavated from the cliff that runs along the north bank of the Dang River. A number have been lost to floods and collapse; some forty are still extant. Twenty-two decorated caves house 34 polychrome statues and 800 m of wall paintings, dating from the Northern Wei to the late-Yuan and early-Ming dynasties (sixth to fourteenth centuries). The site was included within the 1961 designation of the Mogao Caves as a Major National Historical and Cultural Site.

The Five Temple Caves (simplified Chinese: 五个庙石窟; traditional Chinese: 五個廟石窟; pinyin: Wǔgèmiào shíkū) is a series of rock cut Buddhist caves in Subei Mongol Autonomous County, Gansu, northwest China. The complex once numbered twenty-two caves but over the centuries the number was reduced to five, of which four remain today, in a gorge on the left bank of the Danghe River (党河). On the basis of their structure and iconography, one of the caves is dated to the Northern Wei, the other three to the Five Dynasties and Song. The complex lies some 80 kilometres (50 mi) to the south of the Mogao Caves, and together with these, the Western Thousand Buddha Caves, Eastern Thousand Buddha Caves, and Yulin Caves, is one of the five grotto sites in the vicinity of Dunhuang managed by the Dunhuang Academy. In 2013, in recognition of their significance to China, the Five Temple Caves were designated by SACH a Major Historical and Cultural Site Protected at the National Level.

The Longmen Grottoes (simplified Chinese: 龙门石窟; traditional Chinese: 龍門石窟; pinyin: Lóngmén Shíkū; lit. 'Dragon's Gate Grottoes') or Longmen Caves are some of the finest examples of Chinese Buddhist art. Housing tens of thousands of statues of Shakyamuni Buddha and his disciples, they are located 12 kilometres (7.5 mi) south of present-day Luoyang in Henan province, China. The images, many once painted, were carved as outside rock reliefs and inside artificial caves excavated from the limestone cliffs of the Xiangshan (香山) and Longmenshan, running east and west. The Yi River (Chinese: 伊河) flows northward between them and the area used to be called Yique (伊阙; 'The Gate of the Yi River'). The alternative name of "Dragon's Gate Grottoes" derives from the resemblance of the two hills that check the flow of the Yi River to the typical "Chinese gate towers" that once marked the entrance to Luoyang from the south.There are as many as 100,000 statues within the 2,345 caves, ranging from 1 inch (25 mm) to 57 feet (17 m) in height. The area also contains nearly 2,500 stelae and inscriptions, hence the name "Forest of Ancient Stelae", as well as over sixty Buddhist pagodas. Situated in a scenic natural environment, the caves were dug from a 1 kilometre (0.62 mi) stretch of cliff running along both banks of the river. 30% date from the Northern Wei and 60% from the Tang dynasty, caves from other periods accounting for less than 10% of the total. Starting with the Northern Wei dynasty in 493 AD, patrons and donors included emperors, Wu Zetian, members of the royal family, other rich families, generals, and religious groups.

In 2000 the site was added to the UNESCO World Heritage List as "an outstanding manifestation of human artistic creativity," for its perfection of an art form, and for its encapsulation of the cultural sophistication of Tang China.
