Final answer:
Ahmad Shah died due to a nose tumor. Other historical events show the impact of diseases like smallpox on Amerindians and the causes of the Seven Years' War and British National Debt.
Step-by-step explanation:
Ahmad Shah Durrani, the founder of the Durrani Empire in modern-day Afghanistan, died in June of 1773. The cause of Ahmad Shah's death is generally attributed to a nose tumor. Medical reports from that time suggest that he had been suffering from this ailment for several years before his death.
Looking at other historical events, the European diseases that had a profound impact on indigenous populations include smallpox, which was responsible for the greatest number of Amerindian deaths in the late fifteenth and early sixteenth centuries. Moreover, a major cause of the Seven Years' War was growing rivalries between European powers. Additionally, the British National Debt in 1763 was significantly caused by the expenditure during the French and Indian War.
