Why did most Native Americans side with the British rather than the Patriots?

Most Native Americans sided with the British during the American Revolutionary War because they viewed the British as a lesser threat to their lands and way of life. The British had a history of limiting colonial expansion into Native territories through policies like the Proclamation of 1763. In contrast, the Patriots' desire for independence raised concerns that they would expand further westward, encroaching on Native lands. Thus, aligning with the British seemed to offer a better chance of protecting their sovereignty.
