Correct Answer:
B. 1227
The correct answer is 1227. Genghis Khan, the formidable founder and first Great Khan of the Mongol Empire, died in August 1227. His death occurred during the Mongol campaign against the Western Xia dynasty. This date is a crucial historical fact marking the end of his personal reign, though his empire continued to expand under his successors.
- 1209 is incorrect; this was an early period of his conquests.
- 1232 is incorrect; he had already passed away five years prior.
- 1272 is incorrect; this date is significantly later and closer to the death of his grandson, Kublai Khan.
