Today, we learned more about the American Revolutionary War because it is a Massachusetts state holiday called Patriot’s Day. The holiday marks the date of the first battles of the American Revolution which began on April 19, 1775. These battles were in Lexington and Concord, Massachusetts. The American colonists from Britian began their fight for independence from British rule. The war ended in 1781. The United States signed a Declaration of Independence on July 4, 1776 (The 4th of July is a major holiday in the USA), but was not “officially’ recognized as independent until the signing of the Treaty of Paris in 1783.
