Impressment, the practice of forcibly recruiting sailors into naval service, was a contentious issue between the United States and Britain prior to the War of 1812. This practice, carried out by the British navy, involved seizing American sailors and forcing them to serve on British ships. The British claimed they were reclaiming deserters, but many of the men they impressed were actually American citizens. This violation of American sovereignty and individual rights was a major factor in the lead up to the War of 1812.
Impressment was a longstanding practice in the British navy, dating back to the 17th century. During times of war, the British navy faced a constant shortage of sailors, leading them to resort to impressment to fill their ranks. British naval officers would board American ships and search for British deserters or men they believed to be British subjects. However, in their search for these individuals, they often impressed American citizens who had no allegiance to Britain.
The practice of impressment was deeply resented by Americans, who saw it as a violation of their rights as citizens. The British navy's aggressive enforcement of impressment led to numerous incidents between American and British ships, further straining relations between the two nations. Despite diplomatic efforts to resolve the issue, impressment continued to be a source of tension between the United States and Britain.
