Who led the New Model Army during the English Civil War and executed Charles I?

The New Model Army was a revolutionary military force established by Parliament during the English Civil War, and it was Oliver Cromwell who played a pivotal role in its leadership. Cromwell emerged as a skilled military commander and a key figure within the Parliamentarian cause, known for his innovative tactics and ability to inspire his troops.

His leadership was critical in securing numerous victories for the Parliamentarians, contributing significantly to the eventual defeat of the Royalist forces. The climax of this conflict came with the trial and execution of King Charles I in 1649, a decision that Cromwell supported and helped facilitate, marking a turning point in English history toward republicanism and the establishment of the Commonwealth of England.

Other individuals mentioned, such as Richard Cromwell, his son, and Thomas Cromwell, who was a major figure in the Tudor era, followed different legacies. George Monck, on the other hand, later played a role in the Restoration of Charles II but was not directly involved in leading the New Model Army during the Civil War or in the execution of Charles I. Thus, Oliver Cromwell is the figure most accurately associated with both the leadership of the New Model Army and the execution of the king.
