Qing China under strain: from Qianlong's empire to the Opium Wars (History HL)

By 1700 the Qing dynasty — Manchu rulers who had conquered China in 1644 — governed the largest, richest empire on Earth. This micro asks: how strong was that system really, and what forces began to crack it open before 1860?

The nature and structure of imperial rule

Qianlong (ruled 1735–1796) was the Qing dynasty's longest-reigning and most powerful emperor. Under him the empire reached its greatest size, adding Xinjiang and reasserting control over Tibet and Mongolia. His government rested on three pillars.

Why this matters for Paper 3: Qianlong's reign looks like a golden age on the surface — but by its final decades, population growth, corruption and administrative strain were already eating away at the system he built. Cause-and-effect across his reign is exactly what Paper 3 essays reward.

Two long-term pressures built steadily under Qianlong. First, China's population roughly doubled during the 1700s (from about 150 million to over 300 million), straining farmland and food supply without matching growth in the tax base. Second, Qianlong's later years saw the rise of the corrupt official Heshen, who used his closeness to the aging emperor to drain the treasury and place loyal allies in key posts — weakening the very bureaucracy the dynasty depended on.

Use this as your 'roots of crisis' paragraph: Whenever an essay asks about the decline of the Qing, open with Qianlong's era: growing population + weakening bureaucracy + rising corruption. It explains why the state responded so poorly to the rebellions and wars that followed.

The clearest sign that Qing rule was weakening from within was the White Lotus Rebellion (1796–1804), a huge uprising that broke out just as Qianlong handed power to his son.

Why the White Lotus Rebellion matters: It is the first big warning sign of Qing decline BEFORE any Western pressure arrived. It proves the crisis of the 1800s was not only caused by foreign powers — it had deep internal roots in poverty, corruption and a weakening military.

Link internal and external causes: Strong essays argue the Qing crisis had TWO strands that fed each other: internal decay (White Lotus) and external pressure (Opium Wars). Don't treat them as separate stories — a state already strained by rebellion coped far worse with foreign war.

The tribute system and western trade

China's traditional view of foreign relations was the tribute system: neighbouring states sent gifts and envoys to the emperor, symbolically acknowledging China as the centre of civilisation, and received trading privileges in return. Western nations were expected to fit into this same framework — not treated as equal states.

From 1757, all Western trade was restricted to a single port, Canton (Guangzhou), under the Canton System: foreign merchants could only deal through licensed Chinese merchant guilds (the Cohong), pay set fees, and could not travel freely or trade directly with officials. Britain wanted more — a wider market for its manufactured goods and a permanent embassy — but the Macartney Mission of 1793 (a British embassy to Qianlong's court) was rejected because Britain refused to perform the tribute rituals China required.

The trade imbalance behind the crisis: Britain bought huge amounts of Chinese tea, silk and porcelain, but China wanted little from Britain in return — draining British silver. Opium, grown in British India, became the solution: it created Chinese demand and reversed the flow of silver.

Causes and consequences of the Opium Wars

The 'unequal treaties': Historians call Nanjing, Tianjin and Beijing the unequal treaties because China had no real say: they granted extraterritoriality (foreigners tried under their own laws, not China's), fixed low tariffs China could not change, and forced open trade China had never wanted. They humiliated the Qing and became a lasting symbol of national weakness.

Cause-and-effect chain to memorise: Trade imbalance → opium sold to fix it → Lin Zexu's crackdown → First Opium War → Nanjing (1842) → resentment and unresolved disputes → Arrow incident → Second Opium War → Tianjin/Beijing (1860). One continuous chain, not two unrelated wars.
