The American Revolution was not arevolution in the sense of a radical or total change. It was not a sudden andviolent overturning of the political and social framework, such as lateroccurred in France and Russia, when both were already independent nations.Significant changes were ushered in, but they were not breathtaking. Whathappened was accelerated evolution rather than outright revolution. During theconflict itself people went on working and praying, marrying and playing. Mostof them were not seriously disturbed by the actual fighting, and many of themore isolated communities scarcely knew that a war was on.
America′s War of Independence heralded thebirth of three modem nations. One was Canada, which received its first largeinflux of English-speaking population from the thousands of loyalists who fledthere from the United States. Another was Australia, which became a penalcolony now that America was no longer available for prisoners and debtors. Thethird new comer--the United States--based itself squarely on republican principles.
Yet even the political overturn was not asrevolutionary as one might suppose. In some states, notable Connecticut andRhode Island, the war largely ratified a colonial self-rule alreadyexisting.British officials, everywhere ousted, were replaced by a home-growngoverning class, which promptly sought a local substitute for king andParliament.
