Final answer:
The Qing dynasty, which ruled from 1644 to 1912, was the last imperial dynasty in China and ended during the nineteenth century as a result of internal and external pressures.
Step-by-step explanation:
The nineteenth century saw significant political changes with the rise and fall of various dynasties. The Yuan dynasty ended in the fourteenth century, but its impact extended into later periods. Notably, the Qing dynasty, which was the last imperial dynasty of China, came to an end in the nineteenth century. The Qing dynasty, which succeeded the Ming dynasty, lasted from 1644 until 1912. During this time, China faced internal strife, foreign intervention, and was weakened by events such as the Opium Wars. The eventual fall of the Qing dynasty marked the end of thousands of years of imperial rule in China and ushered in the establishment of the Republic of China.
