Historical Trajectory
Phase I: Rise
Nurhaci, leader of the Jianzhou Jurchens, unified the Jurchen clans under the Eight Banners military system and founded the Later Jin dynasty in 1616. His son Hong Taiji proclaimed the Great Qing in 1636. When Ming authority collapsed amid peasant rebellion, the Qing army entered Beijing in 1644 under the Shunzhi Emperor, defeating the rebel Shun dynasty and beginning decades of consolidation that concluded with full conquest in 1683.
Phase II: Zenith
The High Qing era peaked under the Qianlong Emperor (1735–1796), whose Ten Great Campaigns extended the empire from the Sea of Japan to the Pamir Mountains. The dynasty controlled more territory than any previous Chinese dynasty and was the world's most populous state. The Kangxi and Qianlong reigns brought Confucian scholarship, Buddhist patronage, and sustained economic and population growth across a vast multiethnic domain.
Phase III: Decline
After Qianlong's death, internal revolts, official corruption, and foreign pressure eroded Qing authority. Defeat in the Opium Wars forced unequal treaties granting Western powers trading privileges and extraterritoriality. The Taiping Rebellion killed tens of millions, and defeat in the First Sino-Japanese War (1895) cost Taiwan and Korean suzerainty. The Xinhai Revolution of 1911 culminated in the abdication of the Xuantong Emperor in February 1912, ending imperial rule in China.
