"In no long time it became manifest that those political and religious zealots, to whom this deed Charles's execution] is to be ascribed, had committed, not only a crime, but an error. They had given to a prince, hitherto known to his people chiefly by his faults, an opportunity of displaying, on a great theatre, before the eyes of all nations and all ages, some qualities which irresistibly call forth the admiration and love of mankind, the high spirit of a gallant gentleman, the patience and meekness of a penitent Christian. Nay, they had so contrived their revenge that the very man whose life had been a series of attacks on the liberties of England now seemed to die a martyr in the cause of those liberties. No demagogue ever produced such an impression on the public mind as the captive King, who, retaining in that extremity all his regal dignity, and confronting death with dauntless courage, gave utterance to the feelings of his oppressed people, manfully refused to plead before a court unknown to the law, appealed from military violence to the principles of the constitution, asked by what right the House of Commons had been purged of its most respectable members and the House of Lords deprived of its legislative functions, and told his weeping hearers that he was defending, not only his own cause, but theirs. His long misgovernment, his innumerable perfidies, were forgotten. His memory was, in the minds of the great majority of his subjects, associated with those free institutions which he had, during many years, laboured to destroy: for those free institutions had perished with him, and, amidst the mournful silence of a community kept down by arms, had been defended by his voice alone. From that day began a reaction in favour of monarchy and of the exiled house, a reaction which never ceased till the throne had again been set up in all its old dignity."
