During the American Revolution, the legal separation of the Thirteen Colonies from Great Britain occurred on July 2, 1776, when the Second Continental Congress voted to approve a resolution of independence declaring the United States independent from Great Britain rule. After voting for independence, Americans celebrated independence on July 4, the date shown on the much-publicized Declaration of Independence, rather than on July 2, the date the resolution of independence was approved in a closed session of Congress.
Historians have long disputed whether Congress actually signed the Declaration of Independence on July 4, even though Thomas Jefferson, John Adams, and Benjamin Franklin later wrote that they had signed it on that day. Most historians have concluded that the Declaration was signed nearly a month after its adoption, on August 2, 1776, and not on July 4 as is commonly believed.
Coincidentally, both John Adams and Thomas Jefferson, the only signers of the Declaration of Independence later to serve as Presidents of the United States, died on the same day: July 4, 1826, which was the 50th anniversary of the Declaration. Although not a signer of the Declaration of Independence, but another Founding Father who became a President, James Monroe, died on July 4, 1831, thus becoming the third President in a row who died on the holiday. Calvin Coolidge, the 30th President, was born on July 4, 1872, and, so far, is the only U.S. President to have been born on Independence Day.
