What was the cause and the effect of the Battle of Fallen Timbers?

The cause of the Battle of Fallen Timbers was American expansion into the Ohio Valley after the Revolutionary War. After the war, this region, long desired by the Americans, passed into American hands with the Treaty of Paris. But the Native peoples who lived there deeply resented American settlement on their land, and they received some encouragement to resist it from the British Army, stationed in outposts in Canada. President George Washington sent two successive expeditions into the region, and both were defeated soundly. The long-awaited victory of American troops at Fallen Timbers concluded a third campaign led by General Anthony Wayne. The effects of this victory were drastic, especially for the Native peoples of the region. The Ohio Valley Indians were left with little alternative but to give up most of  their lands in the region. They did so in the Treaty of Greenville in 1795. The treaty also had the effect of limiting British influence in the region.
