The main idea behind the American Revolutionary War was a desire for independence from British rule. The colonists, who were frustrated with British control and sought to maintain their autonomy, had various motivations for wanting to break away.
These included the desire for political and economic freedoms, resistance to British taxes and trade restrictions, and the aspiration to expand westward and protect Native American lands.
