Causes of the War:
In the early 1800s, the fledgling United States of America was political independent from Britain, yet severely hampered economically by Britain's insistence on unfavorable trade restrictions with its former colonies. In 1807, Britain introduced a series of restrictions impeding trade with France, with whom Britain was at war. The US contested these restrictions as illegal under international law. it seemed that Great Britain simply did not respect the United States as a sovereign nation.
British Intervenes in the West:
The Northwest Territory, comprising the modern states of Ohio, Indiana, Illinois, Michigan and Wisconsin, had been an area of dispute between the Indian Nations and the United States since the passage of the Northwest Ordinance in 1787. The British Empire had ceded the area to the United States in the Treaty of Paris in 1783; however, British troops continued to occupy the territory along the Great Lakes and were suspected of backing Indian raids against US settlers on the frontier.
