In this AP® US History crash course, we will go over that exact information for one of the many topics to be covered on the exam: Impressment.
Definition
Impressment is defined as the act of forcing men to enlist in military service.
Historical Context
Impressment was most notably used by England in the late 18th and early 19th centuries in order to grow the size of the Royal Navy, although the practice had existed for hundreds of years. The practice was legal under British law, as the navy had the right to forcibly enlist eligible men during times of war. The British began to use impressment on a larger scale in order to grow and maintain their ranks during the Napoleonic Wars. When the navy needed more men, press gangs were sent out to harbors to search ships for sailors eligible for service. Often, those ships carried Americans who were forced into service. Due to impressment, the Royal Navy increased from 10,000 to 140,000 men between the late 18th century and early 19th century.
Why is Impressment Important?

Impressment is important for a couple of reasons. The first and most important reason is that it was one of the main causes of the War of 1812. The practice of impressment caused a growth in tension between the British and the Americans, as the British forcibly enlisted thousands of American men into the Royal Navy from passing ships, and refused to recognize that Americans had renounced their British citizenship. Impressment is also important because it led to the Embargo Act of 1807, which stopped all foreign trade. The Embargo Act was later repealed due to its disastrous economic consequences, and was replaced with the Non-Intercourse Act, which allowed trade with all countries except Britain and France.
