EFFECT 1: Increased nationalism was an effect of all our victories at the various battles we fought. This war was essentially a second war for independence, and it made Americans proud that they could prove themselves to the British.
We have freedom!
Without him, how will we fight? I don't want to fight anymore...
EFFECT 2: Tecumseh, who stepped up to lead the Native Americans' fight against the Americans, was killed in battle. Without him, the Native American unity was crushed, and the Native Americans would unfortunately proceed to be displaced, with more and more of their land taken from them.
Tecumseh is dead! Our leader is dead!
So much work to do!
EFFECT 3: There was an increase in manufacturing in the US, because the British had stopped trade with America. British trade stopped because America had been trading with both the French and the British, and this caused Britain to feel that America was showing preference to the French.
