What was the outcome of Oliver Cromwell's defeat of the king's forces?

After Oliver Cromwell defeated the king's forces during the English Civil War, he effectively took control of England and established a military dictatorship, often referred to as the Protectorate. Cromwell led the New Model Army to victory against King Charles I's royalist forces, which culminated in the king's execution in 1649. Following this event, Cromwell implemented strict governance and appointed himself Lord Protector in 1653, ruling through military force and enforcing Puritanical societal norms. This period was marked by significant political and social changes, including the repression of religious dissent and the promotion of a parliamentary system, although it lacked the stability of a traditional monarchy. Cromwell's regime ultimately reflected his belief in a form of government centered around military authority rather than aristocratic rule.
