The great struggle between the Crown and Parliament happened under James I's successor, Charles I. The House of Commons sent Charles the Petition of Right, demanding to have their rights again, in 1628. Though he accepted the petition, he later closed Parliament and ruled without them for eleven years. It was only after he had money problems as a result of war, that he was forced to call Parliament so they could authorise new taxes. The new Parliament was quite rebellious, so the king shut them down after only three weeks; this was called the Short Parliament. But this did not help the king with his money problem, so he realized that he would need to call another Parliament. Their struggle for power with the king led to the English Civil War. Those supporting the Parliament were called Parliamentarians or 'Roundheads'. In 1649, Charles was put to death by the Rump Parliament and replaced by the military dictator Oliver Cromwell. After Cromwell's death, however, the monarchy was restored in 1660.
