"English Revolution" has been used to describe two different events in English history. The first to be so called—by Whig historians—was the Glorious Revolution of 1688, whereby [[James II os replaced by William III and Mary II as monarch and a constitutional monarchy was established.
In the twentieth-century, however, Marxist historians introduced the use of the term "English Revolution" to describe the period of the English Civil Wars and Commonwealth period (1640–1660), in which Parliament challenged King Charles I's authority, engaged in civil conflict against his forces, and executed him in 1649. This was followed by a ten-year period of bourgeois republican government, the "Commonwealth", before monarchy was restored in the shape of Charles' son, Charles II in 1660.
In The Glorious Revolution of 1688, James II was replaced by William III and Mary II as monarch and a constitutional monarchy was established and was described by Whig historians as the English Revolution. This interpretation suggests that the "English Revolution" was the final act in the long process of reform and consolidation by Parliament to achieve a balanced constitutional monarchy in Britain, and laws were made that pointed towards freedom.
The Marxist view of the English Revolution suggests that the events of 1640 to 1660 in Britain was a bourgeois revolution in which the final section of English feudalism (the state) was destroyed by a bourgeois class (and its supporters) and replaced with a state (and society) which reflected the wider establishment of agrarian (and later industrial) capitalism. Such an analysis sees the English Revolution as pivotal in the transition from feudalism to capitalism and from a feudal state to a capitalist state in Britain.
