Xin Dynasty
9–23 CE
Overview
Wang Mang's interregnum between Western and Eastern Han
Xin Dynasty (House of Wang)
The Xin Dynasty (9-23 CE) was a single-reign interregnum between Western and Eastern Han, founded when the regent Wang Mang deposed the infant Ruzi Ying and proclaimed himself emperor. Wang Mang pursued a sweeping program of institutional reform explicitly modeled on idealized Zhou precedent: redesignation of all land as wangtian ('king's fields'), prohibition of land and slave sales, a multi-denomination bronze currency, and expanded state monopolies. A major Yellow River breach in 11 CE compounded the reforms' economic disruption with flooding, famine and displacement, while frontier relations with the Xiongnu and Western Regions oasis states deteriorated. Cascading peasant rebellions (the Red Eyebrows and Lulin) and the destruction of the last Xin field army at Kunyang in 23 CE brought down the regime within fourteen years; Wang Mang was killed at Chang'an later that year. The 23-25 CE Gengshi regime of Liu Xuan is not modeled on this map; the Eastern Han restoration under Liu Xiu follows in 25 CE.
Territory Phases
Xin Dynasty — Founding & Early Reform9 CE – 14 CE
Wang Mang deposed Ruzi Ying and proclaimed the Xin on 10 January 9 CE (received chronology), inheriting the full late Western Han administrative claim: Guanzhong, the North China Plain, the Sichuan basin, the lower Yangtze, and the residual outer commanderies of the Korean peninsula. The first wave of reforms redesignated all land as wangtian ('king's fields'), banned the sale of land and of slaves, and replaced the stable wushu coinage with a multi-denomination bronze system. Chang'an, restyled Chang'an 常安, remained the capital. The major Yellow River breach of 11 CE fell in this phase and began the flooding, famine and displacement that would feed the later rebellions.
Xin Dynasty — Mid-Reign Crisis & Frontier Loss14 CE – 20 CE
China proper was retained but effective authority in the Western Regions fragmented after Wang Mang's downgrading of Xiongnu and oasis-state titles, and the northern frontier was militarized against the Xiongnu. Goguryeo refused to supply troops in 12 CE; its commander Zou was killed and Wang Mang demoted the polity to 'Xiagouli'. Southwestern tribal areas were in revolt, and the lower Yellow River was still disrupted by the 11 CE breach. Luoyang had been designated Eastern Capital in 12 CE on Zhou precedent, with Chang'an as the Western Capital.
Xin Dynasty — Rebellion, Collapse & Fall of Chang'an20 CE – 23 CE
The Red Eyebrows in southern Shandong and northern Jiangsu and the Lulin of Jingzhou grew from agrarian bands driven by flood and reform dislocation into independently expanding anti-Xin armies. Large tracts of Shandong, northern Jiangsu, Hubei and the lower Yangtze passed out of central control while the government still held Chang'an and the middle Yellow River. The destruction of the last major Xin field army at Kunyang in summer 23 CE opened the road to the capital; Chang'an fell in October 23 CE and Wang Mang was killed on the Jian Terrace of the Weiyang Palace, ending the dynasty.
Key Rulers
Wang Mang (王莽; courtesy name Jujun 巨君)
9 CE – 23 CE
★★★
Nephew of Grand Empress Dowager Wang Zhengjun, Wang Mang rose through consort-clan influence, court service, a cultivated Confucian reputation, and successive regencies over the child emperors Ping and Ruzi Ying, holding the pre-accession titles Shehuangdi 攝皇帝 and Jiahuangdi 假皇帝 ('Regent/Acting Emperor', c. 6-9 CE) before deposing Ruzi Ying and founding the Xin in 9 CE. Wang Mang was the sole Xin emperor: he pursued the most ambitious institutional reform program of early imperial China, modeled explicitly on classical Zhou precedent, whose disruption combined with the 11 CE Yellow River breach and cascading rebellions to destroy his dynasty within fourteen years. He was killed at Chang'an in 23 CE.
Key Events
Usurpation and Foundation of the Xin9 CE
Wang Mang, who had governed as regent under the pre-accession titles Shehuangdi and Jiahuangdi since c. 6 CE, deposed the infant Ruzi Ying and proclaimed the Xin ('New') dynasty in 9 CE, adopting the reign title Shijianguo. The received chronology dates the proclamation to 10 January 9 CE, a Julian-calendar conversion that is not universally agreed (a variant reckoning gives 15 January); this map records only the year. Wang Mang was the sole Xin emperor. Ruzi Ying, demoted to Duke of Ding'an, was never a Xin sovereign.
First Land and Currency Reforms9 CE
Wang Mang redesignated all land empire-wide as wangtian ('king's fields'), banned the sale of land and of slaves (renamed 'private retainers'), and ordered households holding surplus above the permitted allotment to redistribute it. He simultaneously replaced the stable Han wushu coinage with a complex multi-denomination bronze currency system. The measures drew explicitly on the Zhouli's idealized Zhou institutional model but disrupted commerce and provoked immediate elite resistance.
Major Yellow River Breach11 CE
A major breach of the Yellow River's course in 11 CE inundated the lower river plain, triggering prolonged flooding, displacement, famine and epidemic disease over the following years. Archaeological evidence from the Sanyangzhuang farming settlement, buried intact beneath flood deposits, corroborates the scale and suddenness of the inundation. The disaster compounded the reform program's economic disruption and supplied much of the demographic and economic fuel for the later Red Eyebrows and Lulin rebellions. It followed earlier, less severe course disturbances in the final years of Western Han; the sources do not support drawing a sharp line between the two episodes.
Goguryeo's Refusal and Punitive Demotion to Xiagouli12 CE
Ordered to supply troops for a campaign against the Xiongnu, Goguryeo refused; in the ensuing clash its commander Zou (騶) was killed by the Xin general Yan You. Wang Mang responded by punitively renaming and demoting the polity from Gaogouli to 'Xiagouli' ('Lower Goguryeo') — a deliberate insult recorded in the Chinese sources. The later identification of the slain commander Zou with King Yuri of Goguryeo is disputed and is not asserted here.
Fragmentation of Authority in the Western Regions14 CE
Wang Mang's downgrading of Xiongnu and Western Regions oasis-state titles antagonized frontier rulers and precipitated a progressive breakdown of the tributary and protectorate relationships Western Han had built across the Tarim Basin. Authority eroded unevenly rather than collapsing at once: Chinese officers and garrison detachments persisted in parts of the region into the dynasty's final years even as the Protectorate's overall reach contracted.
Rise of the Red Eyebrows and Lulin Rebellions17 CE
Agrarian bands in southern Shandong and northern Jiangsu, marked out by painting their eyebrows red, and the Lulin ('Green Forest') fighters based in the Jingzhou hills of Hubei coalesced from flood- and reform-driven banditry into large, independently expanding anti-Xin armies beginning in 17 CE. Both movements grew through the early 20s CE into the principal military threats that would destroy the Xin regime.
Battle of Kunyang23 CE
In summer 23 CE, a Lulin and Han-restorationist force under Liu Xiu held the town of Kunyang in Yingchuan Commandery against the main Xin field army. The Hanshu reports the besieging force at several hundred thousand, a figure attributed to the Hanshu itself rather than an established fact; modern estimates are considerably lower. A relief sortie led by Liu Xiu, the death of the Xin commander Wang Xun, and a sudden storm broke the siege and destroyed the last major Xin army, opening the road to Chang'an.
Fall of Chang'an and Death of Wang Mang23 CE
Following the rout at Kunyang, rebel forces advanced on the capital and breached Chang'an later in 23 CE. Wang Mang made a last stand on the Jian Terrace of the Weiyang Palace, where the merchant Du Wu killed him and took his seal-cord; Gongbin Jiu then beheaded the body. The sack of the palace and the display of Wang Mang's head ended the Xin dynasty.
