The American colonies were a group of territories established by European powers, primarily England, along the eastern coast of what is now the United States. These colonies were founded for various reasons, including economic opportunities, religious freedom, and the expansion of trade. By the 18th century, there were 13 main colonies, each with its own government and way of life. The colonies played a significant role in the history of North America. They developed distinct cultures and economies, ranging from agriculture in the southern colonies to trade and industry in the northern ones. Tensions between the colonies and Great Britain eventually led to the American Revolution, resulting in the colonies gaining independence.
