Final answer:
The Taiping Rebellion, a major civil war that aimed to overthrow the Qing dynasty, was a consequence of the disorder following the Opium Wars.
Step-by-step explanation:
The period of disorder following the Opium Wars saw several uprisings in China, one of which was the Taiping Rebellion. This was a massive civil war in southern China from 1850 to 1864, led by Hong Xiuquan who wanted to overthrow the ruling Qing dynasty and establish the Taiping Heavenly Kingdom. As a result of the weakened Qing dynasty due to factors such as the opium crisis and failure to maintain infrastructure, the Taiping Rebellion became the largest and one of the most devastating conflicts of the 19th century, with millions of fatalities.
