166-628: A limited engagement at Mayi involving the assassination of the Chanyu would throw the Xiongnu realm into chaos and benefit the Han. When this plot failed in 133 BC, Emperor Wu launched a series of massive military invasions into Xiongnu territory. The assault culminated in 119 BC at the Battle of Mobei , when Han commanders Huo Qubing ( d.  117 BC ) and Wei Qing ( d.  106 BC ) forced

249-629: A series of military campaigns to quell the Xiongnu. The Xiongnu were eventually defeated and forced to accept a status as Han vassals , and the Xiongnu confederation fragmented. The Han conquered the Hexi Corridor and Inner Asian territory of the Tarim Basin from the Xiongnu, helping to establish the Silk Road . The lands north of the Han's borders were later overrun by the nomadic Xianbei confederation. Emperor Wu also launched successful conquests in

The conflict ended with the Kushans withdrawing because of lack of supplies. In AD 91, the office of Protector General of the Western Regions

1162-428: A series of reforms that limited the power of these kingdoms in 145, dividing their former territories into new commanderies under central control. Kings were no longer able to appoint their own staff; this duty was assumed by the imperial court. Kings became nominal heads of their fiefs and collected a portion of tax revenues as their personal incomes. The kingdoms were never entirely abolished and existed throughout

1245-459: A state pension and a territorial fiefdom . Holders of the rank immediately below, that of ordinary marquess, received a pension, but had no territorial rule. Scholar-bureaucrats who served in government belonged to the wider commoner social class and were ranked just below nobles in social prestige.

However, Tanshihuai's confederation disintegrated after his death. Ban Chao ( d.  AD 102 ) enlisted the aid of the Kushan Empire , which controlled territory across South and Central Asia, to subdue Kashgar and its ally Sogdiana. When

1992-741: The Chu–Han Contention , the resulting Han dynasty was named after the Hanzhong fief. China's first imperial dynasty was the Qin dynasty (221–207 BC). The Qin united the Chinese Warring States by conquest, but their regime became unstable after the death of the first emperor Qin Shi Huang . Within four years, the dynasty's authority had collapsed in a rebellion. Two former rebel leaders, Xiang Yu ( d.  202 BC ) of Chu and Liu Bang ( d.  195 BC ) of Han , engaged in

2158-665: The Tang dynasty (618–907) author Jiang Fang in his Essay on the Art of Constructing Mountains with Rice (c. 845). A raised-relief map made of wood representing all the provinces of the empire and put together like a giant 0.93 m ( 10 ft ) jigsaw puzzle was invented by Xie Zhuang (421–466) during the Liu Song dynasty (420–479). Shen Kuo (1031-1095) created a raised-relief map using sawdust, wood, beeswax, and wheat paste. His wooden model pleased Emperor Shenzong of Song , who later ordered that all

2241-645: The Xin dynasty (9–23 AD) established by the usurping regent Wang Mang , and is thus separated into two periods—the Western Han (202 BC – 9 AD) and the Eastern Han (25–220 AD). Spanning over four centuries, the Han dynasty is considered a golden age in Chinese history , and had a permanent impact on Chinese identity in later periods. The majority ethnic group of modern China refer to themselves as

2324-613: The Xiongnu , who were estranged from Han until their leader Bi ( 比 ), a rival claimant to the throne against his cousin Punu ( 蒲奴 ), submitted to Han as a tributary vassal in AD 50. This created two rival Xiongnu states: the Southern Xiongnu led by Bi, an ally of Han, and the Northern Xiongnu led by Punu, an enemy of Han. During the turbulent reign of Wang Mang, China lost control over

2407-565: The Yellow Turban Rebellion and Five Pecks of Rice Rebellion in 184 AD, largely because the court did not want to continue to alienate a significant portion of the gentry class who might otherwise join the rebellions. The Yellow Turbans and Five-Pecks-of-Rice adherents belonged to two different hierarchical Taoist religious societies led by faith healers Zhang Jue ( d.  184 AD ) and Zhang Lu ( d.  216 AD ), respectively. Zhang Lu's rebellion, in what

Ranked immediately below the emperor were the kings who were of the same Liu family clan. The rest of society, including nobles lower than kings and all commoners excluding slaves, belonged to one of twenty ranks ( ershi gongcheng 二十公乘 ). Each successive rank gave its holder greater pensions and legal privileges. The highest rank, of full marquess , came with

Under Emperor Ling ( r.  168–189 AD ) the eunuchs had the partisan prohibitions renewed and expanded, while also auctioning off top government offices. Many affairs of state were entrusted to the eunuchs Zhao Zhong ( d.  189 AD ) and Zhang Rang ( d.  189 AD ) while Emperor Ling spent much of his time roleplaying with concubines and participating in military parades. The Partisan Prohibitions were repealed during
