How did issues of trade lead to the War of 1812?

The British wanted to restrict Americans trade with France, causing tension between Great Britian and America

The War of 1812 was a conflict fought between the United States and the United Kingdom, with their respective allies, from June 1812 to February 1815. Historians in Britain often see it as a minor theater of the Napoleonic Wars; historians in the United States and Canada see it as a war in its own right.
