See it on the History map →What happened
Founded by Liu Bang, a commoner rebel, after Qin's collapse, the Han kept Qin's centralized state but softened its laws and made Confucianism the official ideology. Officials were increasingly chosen for learning. Emperor Wu (141–87 BC) expanded into Central Asia, Vietnam and northern Korea, where commanderies such as Lelang were set up in 108 BC. A census of AD 2 counted about 58 million people. Wang Mang's usurpation (AD 9–23) divides it into Western and Eastern Han; revolts and warlords ended it in 220.
Why it matters
China's majority still call themselves Han. Its blend of Confucian scholarship and central bureaucracy lasted, with breaks, until 1912. At its height the Han rivaled Rome in size.
How we know
Sima Qian's Records and Ban Gu's History of the Han, the AD 2 census, tombs such as Mawangdui, and thousands of administrative documents on bamboo and wood.

Connections (4)
▸Confucius inspired the state ideology of Han dynastyWell documented
The connection
Confucius taught that order comes from virtuous rulers, proper ritual and family duty. Three centuries later, Han Emperor Wu (141–87 BC) made the Confucian classics the basis of official learning, founding an Imperial Academy in 124 BC to train officials. Confucianism, blended with Legalist administration, became the ideology of the Chinese state for two thousand years.
When and how
Chang'an, the Han capital, 2nd century BC; Emperor Wu and the scholar Dong Zhongshu.
How we know
Han histories record the academy and the official promotion of the Five Classics; officials' memorials cite Confucius constantly.
Debates and open questions
How 'Confucian' Han government really was in practice is debated, since it kept much of Qin's Legalist machinery.
▸Han dynasty opened Silk RoadMostly agreed
The connection
Han Emperor Wu sent Zhang Qian west to find allies against the Xiongnu nomads. Zhang's reports of Central Asian kingdoms and superb horses led the Han to campaign westward, build garrisons and extend walls through the Gansu corridor, making caravan travel safer. Chinese silk then flowed regularly toward Persia and Rome.
When and how
From Chang'an through the Hexi (Gansu) corridor to the Tarim Basin and the Ferghana valley, c. 138–100 BC.
How sure are we?
Sima Qian's account of Zhang Qian, and Han frontier documents from Xuanquan logging passing envoys and travelers.
Debates and open questions
Trade across Central Asia predated the Han; how much the Han 'opened' routes versus protected and formalized existing exchange is debated.
▸Han dynasty invented PapermakingWell documented
The connection
Han craftsmen beat hemp and other fibers into pulp, spread it on screens and dried it into sheets. Early paper often wrapped goods; by the AD 100s it was widely used for writing. Cai Lun's improved recipe of AD 105 was promoted at court, and paper gradually replaced bamboo and silk in Chinese offices.
When and how
Han China, 2nd century BC to AD 105; Cai Lun, a palace official at the capital Luoyang.
How we know
Paper from securely dated Han tombs and frontier posts, such as Fangmatan and Xuanquan, predates Cai Lun by centuries; no older paper has been found anywhere.
Debates and open questions
Dates of some early finds, such as the Baqiao paper, are disputed, and exactly what Cai Lun added to methods already centuries old is unclear.
▸Qin Shi Huang, first emperor of China was followed by Han dynastyWell documented
The connection
Qin's harsh laws, heavy taxes and forced labor provoked revolts soon after the First Emperor died in 210 BC. Rebels toppled his heir in 207–206 BC. Liu Bang, a minor official of peasant background, won the civil war that followed against his rival Xiang Yu and founded the Han, keeping much of Qin's system but with milder laws.
When and how
China, 210–202 BC; the Chen Sheng uprising (209 BC), Liu Bang and Xiang Yu.
How we know
Sima Qian's Records describe the fall; excavated documents show early Han law codes closely copying Qin ones.
Debates and open questions
How harsh Qin rule really was is debated, since the Han, who wrote its history, had reason to blacken it.
