In what year did Marines defend the American Legation in Peking, China during the Boxer Rebellion?

The defense of the American Legation in Peking, China, during the Boxer Rebellion occurred in the year 1900. This event was part of a larger uprising against foreign influence and Christianity in China, where various international forces, including the United States Marine Corps, were called to protect the lives and property of foreign nationals. The Marines played a crucial role in securing the legation and ensuring the safety of the American citizens and diplomats who were trapped during the siege.

This period is significant for the U.S. military, as it demonstrated the increasing role of American forces abroad and their commitment to protecting U.S. interests. The other years presented do not correspond to the events of the Boxer Rebellion or any American military involvement in Peking during that timeframe, which is why they are not applicable to this question. The context reinforces the importance of the Marines' participation in global conflicts and their readiness to respond to crises in international settings.
