Getting into War
British policies that supported the war against Napoleon and the defence of Canada contributed to the outbreak of a second war with the United States.
The Royal Navy and an economic blockade enforced by British warships formed two of Britain’s most powerful weapons in the struggle against Napoleon. As the demand for skilled sailors increased, the Royal Navy ignored American sovereignty and citizenship by stopping American ships at sea and forcibly recruiting anyone considered to be a British subject. At the same time, British commercial regulations dictated the conditions under which Americans would be allowed to trade with Europe. Reacting to what Americans perceived as a long series of British provocations, the United States declared war on 18 June 1812.
