At the time of the American Revolution (1765–83), the British Empire had colonies in India, Africa, the Caribbean, the Pacific, Canada, Ireland, and Gibraltar. The thirteen rebellious American colonies accounted for half of the total number of provinces in the British world in 1776. What of the loyal half? Why did some of Britain’s subjects feel so aggrieved that they wanted to establish a new system of government, while others did not rebel? In this authoritative history, Trevor Burnard and Andrew Jackson O’Shaughnessy show that understanding the long-term causes of the American Revolution requires a global view.
