The Opium Wars primarily arose due to a conflict over what?

The correct answer is rooted in the historical context of the Opium Wars, which primarily involved a trade dispute centered around opium. The wars were triggered by Britain's trade of opium to China, where it was illegal and harmful to its population. The Chinese government attempted to suppress this trade due to its negative social and economic implications. Britain's insistence on continuing the opium trade, despite China's opposition and the resulting social issues, led to rising tensions, ultimately culminating in military conflict. Thus, the essence of the conflict is firmly tied to the illegal drug trade rather than general manufactured goods, religious factors, or colonial disputes.

This situation illustrates how economic interests and illicit trade practices can escalate into significant political and military confrontations.
