To which level did the economic factor of taxation affect the people of Massachusetts, and how did it mobilize people to resist? How did the crisis outbreak in Lexington and Concord? Although focusing on the history of the American Revolution in Massachusetts, Boutkhil Guemide not only studies the specific case of the third oldest British colony in North America but also reveals the whole background and process of the American revolutionary movement that would emerge in a snowball effect after the Boston Massacre and the famous battles of April 19, 1775. Greatly documented, a gripping chapter of history.
