The American Revolutionary movement refers to the series of events, ideologies, and actions taken by the thirteen American colonies to gain independence from British rule in the late 18th century. This movement was fueled by a growing sense of American identity, dissatisfaction with British governance, and Enlightenment ideals, ultimately leading to the Declaration of Independence in 1776 and the subsequent Revolutionary War. It played a crucial role in shaping colonial society and culture, as it united diverse groups against a common enemy and inspired a new sense of individual rights and democratic governance.
