The outcome of the English Revolution (1642–1651) was the temporary dismantling of the monarchy and the establishment of the Commonwealth under Oliver Cromwell. This revolution resulted in King Charles I being executed for treason, profoundly altering the balance of power between the monarchy and Parliament. Although the monarchy was later restored, the events underscored the growing power of parliamentary governance and set precedents for future political conflicts. This period marked an essential shift towards constitutional monarchy and the evolution of modern democratic principles in Britain.
