American naval history traces its roots back to the colonial period when the first American ships were used for trade and defense. The establishment of the Continental Navy during the American Revolution marked a significant step, as it aimed to challenge British naval dominance. In the 19th century, the U.S. Navy expanded significantly, playing crucial roles in conflicts like the War of 1812 and the Mexican-American War. The Navy continued to evolve through the Civil War, the Spanish-American War, and both World Wars, becoming a key component of American military power and global presence.
