Following the death of the Jiaqing Emperor, Aisin-Gioro Minning was enthroned as the Daoguang Emperor, inaugurating a reign later marked by fiscal strain, internal unrest, and mounting foreign pressures.
Jahangir Khoja, an exiled heir of the Khojas, invaded Xinjiang from Kokand and seized major cities (including Kashgar), exposing Qing vulnerabilities on the empire’s western frontier early in Daoguang’s reign.
After a series of Qing counteroffensives, Jahangir Khoja was betrayed and captured, then sent to Beijing—allowing the Qing to restore control over the key oasis cities in southern Xinjiang.
Jahangir Khoja was executed after his capture, symbolizing the reassertion of Qing authority in Xinjiang and concluding the most acute phase of the revolt that had threatened Qing control in the Tarim Basin.
Confronted with a deepening opium crisis, the Daoguang Emperor empowered senior official Lin Zexu to halt the opium trade at Guangzhou, setting in motion the confrontation that escalated into war with Britain.
An edict issued under the Daoguang Emperor emphasized severe punishments for opium smuggling as Lin Zexu intensified enforcement at Guangzhou, further sharpening the standoff with foreign merchants.
Lin Zexu began the public destruction of a massive quantity of confiscated opium at Humen, a dramatic enforcement action that became a direct catalyst for British military intervention and the First Opium War.
Armed conflict between Britain and Qing China expanded after escalating maritime and trading disputes linked to the opium crackdown, testing Qing defenses and exposing technological and logistical gaps.
Qing representatives and Britain signed the Treaty of Nanking, ending the war and imposing major concessions including opening treaty ports, indemnities, and the cession of Hong Kong—an enduring turning point in Qing foreign relations.
The Daoguang Emperor ratified the Treaty of Nanking, formalizing the settlement and enabling implementation of the new treaty-port system and related commercial provisions under Qing authority.
The supplementary Treaty of the Bogue granted Britain exterritoriality and most-favoured-nation status, deepening the legal and diplomatic constraints on Qing sovereignty established after the First Opium War.
The Daoguang Emperor died in Beijing; his son Yizhu succeeded as the Xianfeng Emperor, marking the end of a reign in which Qing governance faced intensified internal strains and transformative foreign-imposed treaties.
