The American Revolution began as a result of growing tensions between the American colonies and Great Britain. Key events led to the outbreak of war in 1775, including several Acts passed by the British Parliament that taxed the colonies without representation. In response, colonists organized protests and boycotts of British goods. The Declaration of Independence was issued in 1776, declaring the colonies independent states no longer under British rule. The American Revolutionary War ensued as the newly formed American forces fought the British for independence.
