What role did Freemasonry play in the American Revolution?

Freemasons and their lodges played a quiet yet prominent part in the events surrounding the American Revolution 12. The Green Dragon Tavern in Boston, which served as a Masonic hall where the Grand Lodge of Massachusetts was organized under Grand Master Joseph Warren, functioned as a major hub of revolutionary planning 2. Leaders including Samuel Adams, Paul Revere, Warren, John Hancock, and James Otis met there, and the Boston Tea Party was planned and executed by a club formed within the lodge 2.

Across the colonies, numerous Masons supported the revolutionary cause, and several signers of the Declaration of Independence were members of the Craft, including Benjamin Franklin, John Hancock, William Hooper, Matthew Thornton, William Whipple, Philip Livingston, and Thomas Nelson 2. Following the conflict, the former Provincial Grand Lodges in the newly independent states separated from British jurisdiction and established themselves as independent Grand Lodges 3.

While Masonic influence was substantial, some popular claims overstate it; for example, the Great Seal of the United States is not a Masonic design, and Benjamin Franklin was the only Freemason on the committee appointed in 1776 to draft it 3. Furthermore, documenting the full extent of Masonic participation remains complicated, as wartime conditions destroyed many early lodge records 2, and monuments honoring Revolutionary heroes who were Masons later suffered intentional defacement and destruction 3.
