1599-1658. English general and politician, Puritan leader of the Parliamentary side in the Civil War. He raised cavalry forces (later called Ironsides) which aided the victories at Edgehill 1642 and Marston Moor 1644, and organized the New Model Army, which he led (with General Fairfax) to victory at Naseby 1645. As Lord Protector (ruler) from 1653, he established religious toleration and raised Britain's prestige in Europe on the basis of an alliance with France against Spain. Cromwell was born at Huntingdon, NW of Cambridge, son of a small landowner. He entered Parliament 1629 and became active in events leading to the Civil War. Failing to secure a constitutional settlement with Charles I 1646-48, he defeated the 1648 Scottish invasion at Preston. A special commission, of which Cromwell was a member, tried the king and condemned him to death, and a republic was set up. The Levellers demanded radical reforms, but he executed their leaders in 1649. He used terror to crush Irish clan resistance 1649-50, and defeated the Scots (who had acknowledged Charles II) at Dunbar 1650 and Worcester 1651. In 1653, having forcibly expelled the corrupt `Rump' Parliament, he summoned a convention (`Barebone's Parliament'), soon dissolved as too radical, and under a constitution (Instrument of Government) drawn up by the army leaders, became Protector (king in all but name). The parliament of l654-55 was dissolved as uncooperative, and after a period of military dictatorship, his last parliament offered him the crown; he refused because he feared the army's republicanism. Cromwell was a critic of Charles I and became active in events leading to the Civil War. He signed the king's death warrant in 1648 and in the power struggle that followed sided with the army and the establishment of the Commonwealth. He expelled parliament and established the Protectorate. His foreign policy was dictated by religious and commercial considerations; he found no constitutional basis for his rule and refused the crown 1657.
