The father would have permitted Protestantism if Protestantism would have submitted to universal monarchy. There would have been small difficulty in the early part of his reign in effecting a compromise between Rome and Augsburg, had the gigantic secular ambition of Charles not preferred to weaken the Church and to convert conscientious religious reform into political mutiny; a crime against him who claimed the sovereignty of Christendom. The materials for the true history of that reign lie in the Archives of Spain, Austria, Rome, Venice, and the Netherlands, and in many other places. When out of them one day a complete and authentic narrative shall have been constructed, it will be seen how completely the policy of Charles foreshadowed and necessitated that of Philip, how logically, under the successors of Philip, the Austrian dream of universal empire ended in the shattering, in the minute subdivision, and the reduction to a long impotence of that Germanic Empire which had really belonged to Charles. Unfortunately the great Republic which, notwithstanding the aid of England on the one side and of France on the other, had withstood almost single-handed the onslaughts of Spain, now allowed the demon of religious hatred to enter into its body at the first epoch of peace, although it had successfully exorcised the evil spirit during the long and terrible war. There can be no doubt whatever that the discords within the interior of the Dutch Republic during the period of the Truce, and their tragic catastrophe, had weakened her purpose and partially paralysed her arm. When the noble Commonwealth went forward to the renewed and general conflict which succeeded the concentrated one in which it had been the chief actor, the effect of those misspent twelve years became apparent. Indeed the real continuity of the war was scarcely broken by the fitful, armistice. The death of John of Cleve, an event almost simultaneous with the conclusion of the Truce, seemed to those gifted with political vision the necessary precursor of a new and more general war. The secret correspondence of Barneveld shows the almost prophetic accuracy with which he indicated the course of events and the approach of an almost universal conflict, while that tragedy was still in the future, and was to be enacted after he had been laid in his bloody grave. No man then living was so accustomed as he was to sweep the political horizon, and to estimate the signs and portents of the times. No statesman was left in Europe during the epoch of the Twelve Years' Truce to compare with him in experience, breadth of vision, political tact, or administrative sagacity.
