(1)Oliver Cromwell established a republic called the Commonwealth of England (1649-1660) and ruled as a dictator close after the overthrow of King Charles I. James Harrington was then a leading philosopher of republicanism. The collapse of the Commonwealth of England in 1660 and the restoration of the monarchy under Charles II discredited republicanism among the ruling circles of England. However celebrated liberalism, and emphasis on the rights of John Locke, who played an important role in the Glorious Revolution of 1688. However, republicanism flourished in the "country" party of the early 18th century, denounced the corruption of the party "tribunal", producing a political theory that strongly influenced the American colonists.
