"Charles was put to death at the time when his influence, long on the wane, was at its lowest point. He had outlived his usefulness, alienated every party, political and religious, betrayed and deserted his most intimate accomplices, and deceived his subjects generally. Charles had talents above the average. With much of the culture and refinement of his epoch, he lacked that breadth of view, consistency of purpose, and firmness of will which distinguish a good ruler and a powerful statesman. His manliness was not of the highest order, and his courage was spasmodic, which is not to be wondered at, since in courting success Charles acted on the vicious principle that the end justifies the means. The oft-repeated assertion that Charles died a martyr to religion and to Episcopacy cannot be maintained by any one cognizant of the unscrupulous stratagems which he used in order to restore himself to absolute power, such as the temporary countenancing of Presbyterianism in Scotland in 1641, and his offer to re-establish popery in Ireland in 1645."
