The British Navy played a significant role in the American Revolution as a powerful military force that supported British colonial efforts, engaged in naval battles, and provided vital supplies and transportation, which occurred from 1775 to 1783, primarily in the waters surrounding the American colonies and other strategic locations, with the aim of maintaining British control and suppressing the uprising of the American colonists seeking independence.
