In 1809, James Madison became President of America. He like, Thomas Jefferson, wanted to stop Great Britain from interfering in America's success. He wanted to do it in a peaceful way. The U.S. had a huge shipping industry and Great Britain wanted to slow it down or stop it. Many Republican congressmen wanted to stop Great Britain from interfering. Some young congressmen who felt very strongly about this were nicknamed the "War Hawks." They argued in Congress that the U.S. needed to declare war on Great Britain!
