John Hancock was an American Founding Father, merchant, statesman, and prominent Patriot of the American Revolution. He served as president of the Second Continental Congress and was the first and third governor of the Commonwealth of Massachusetts. He is remembered for his large and stylish signature on the United States Declaration of Independence, so much so that in the United States, John Hancock or Hancock has become a colloquialism for a person's signature. He also signed the Articles of Confederation, and used his influence to ensure that Massachusetts ratified the United States Constitution in 1788.

The Second Continental Congress was the late-18th-century meeting of delegates from the Thirteen Colonies that united in support of the American Revolution and the Revolutionary War, which established American independence from the British Empire. The Congress constituted a new federation that it first named the United Colonies, and in 1776, renamed the United States of America. The Congress began convening in Philadelphia, on May 10, 1775, with representatives from 12 of the 13 colonies, after the Battles of Lexington and Concord.
