Why did Britain blockade us ships in 1805?

In 1805, Britain blockaded U.S. ships primarily due to the ongoing Napoleonic Wars and the desire to weaken France and its allies. The British aimed to restrict trade between the United States and France, as American ships were seen as a means of circumventing British naval dominance. This blockade contributed to rising tensions between the U.S. and Britain, ultimately leading to the War of 1812.
