When did the war with England and the United States begin?

Being the possession of Great Britain (England), the American colonies developed rapidly economically. Observing these trends, England, trying to prevent the strengthening and separation of its colonies, introduced a number of sanctions and laws that hindered the development of the economy of 13 colonies. The backlash was such an event as the Boston Tea Party in 1773, during which a group of Americans threw a batch of British tea into the sea. This event is the beginning of the struggle, but it was the war that began in 1775.
