After 900 American ships were seized by Napoleon's Continental System (1806) and the British Orders in Council (1807), the U.S. released the Embargo Act of 1807, which prohibited American ships from sailing to any foreign ports and closed American ports to British ships. Some Americans were unhappy with the halting of overseas export/import, contributing to a meeting in 1814.
The Embargo Act was replaced by the Non-Intercourse Act of 1809, which lifted all embargoes on American shipping except for those bound for British or French ports. This was then replaced in 1810 by Macon's Bill Number 2. This lifted all embargoes but offered that if either France or Great Britain were to cease their interference with American shipping, the United States would reinstate an embargo on the other nation. Napoleon, seeing an opportunity to make trouble for Great Britain, promised to leave American ships alone, and the United States reinstated the embargo with Great Britain and moved closer to declaring war.
