These wars triggered conflict in North America, when Britain shut down trade with the US and France. This made the US lose money, so they declared war on Canada which was a british colony. When the Americans invaded Canada, they expected the colonists to join them in thier fight, but instead, the colonists fought back. They did this partly because the Catholic Church opposed this. The War ended in the treaty of Ghent
