During the American Revolutionary War, many Native American tribes faced difficult choices about which side to support. Overall, a significant number of Native Americans sided with the British, primarily because the British offered to protect their lands against encroachment by American settlers. The British had a longstanding policy of limiting colonial expansion into Native territories, which appealed to many tribes that were concerned about losing their lands.
However, it's important to note that not all Native Americans sided with the British; some tribes, such as the Oneida and a few others, supported the American patriots. Various tribes made decisions based on their own interests, local circumstances, and historical relationships with the British or American settlers.
So, while many Native Americans ultimately sided with the British during the Revolutionary War, the situation was complex and varied widely among different tribes.
