American colonial leaders in the 1760's and 1770's insisted that they were just asserting their rights as free-born subjects of British empire. They believed that English Constitution was the greatest source of freedom on Earth and their forefathers who came to America did not intend to separate themselves from that Constitution. In time, of course, they sought a different path. Guy Chet, Professor of History at the University of North Texas, talks with us about his latest book, The Colonists' American Revolution: Preserving English Liberty 1607-1783.
