I want to know the answer to the following question:
What long held tradition helped make Boston a wealthy port?
All the background I'm provided with is that "Many of the crucial events of the American Revolution—the Boston Massacre, the Boston Tea Party, Paul Revere's midnight ride, the battles of Lexington and Concord and Bunker Hill, the Siege of Boston, and many others—occurred in or near Boston.". Is that enough to answer the question?
