During the War of 1812, the American economy went through many changes. This lack of international trade caused the Americans to begin manufacturing everything that they needed. Decaying, centuries-old factories in the United States were restored and reused, while new factories were being built.

One indication that the War of 1812 could have been avoided is that all of the problems cited by Madison in justifying the war were long running concerns that had risen and fallen in importance over the previous two decades. The U.S. and Great Britain had managed their differences without resort to war.

While the War of 1812 had virtually no impact in England, it did assure the survival of the British colonies in Canada, and ultimately paved the way for the Canadian Confederation – the precursor to the nation of Canada.

The main result of the War of 1812 has been two centuries of peace between both countries. After Napoleon’s defeat in 1814, Britain was no longer at war with France, and restrictions on trade ended. The British suspended their policy of impressment of American sailors since there was no need to resume it.

How did the War of 1812 end? It ended in American victory with substantial territorial gains after the Battle of New Orleans.

Causes of the War of 1812:

• Britain’s seizure of American ships and impressment of sailors.
• America’s resentment of Britain.
• American belief that British were arming Native Americans and inciting them to riot.
• American “War Hawks” wanting to annex Florida and Canada.

Why did Congress declare war on Britain in 1812? British interference with trade and impressment at sea, also the British took sides with the Native Americans.

In June 1812, the United States declared war against Great Britain in reaction to three issues: the British economic blockade of France, the induction of thousands of neutral American seamen into the British Royal Navy against their will, and the British support of Native American tribes along the Great Lakes frontier.
