USA HISTORY

Detailed explanation-1: -The British saw Indian territory as a crucial buffer against U.S. aggression and had already shown support to an increasingly militant tribal coalition along the Great Lakes frontier. In June 1812, U.S. President James Madison signed a declaration of war against Britain, initiating the War of 1812.

Detailed explanation-2: -Britain also maintained a network of forts and trading outposts on the frontiers, like Fort Niagara and Fort Detroit. From these bases, British officers could encourage groups of Native American warriors to launch devastating raids on communities that supported the American cause.

Detailed explanation-3: -Officials in London feared that an increased Anglo-American presence in the western territory would encourage Native American violence that, when paired with resistance from French settlers in the region, would incite another expensive conflict for the empire.

Detailed explanation-4: -During the American Revolution, the majority of American Indian Nations allied themselves with the British in order to preserve their culture and stop encroachment upon their lands.
