English civil war Why did the royalist lose?

Answer 1

The royalist forces were extinguished, they had run out of money, the royalist leaders had developed divided ideas about what went wrong and how it could have been done, and Charles' constant refusal to take the initiative and charge into battle meant that the royalists lost the upper hand that they were dealt many times. Parliament on the other hand, was a strong fighter, and the brilliance of Pym's union with the Scots, and Parliament's control of the seas and the richer areas of England, aswell as their creation of a powerful, trained and disciplined New Model Army meant that they ultimately had the power in the end.
