This very unmeaning character of the dispute increased the difficulty of ending it. In wars of conquest or of principle, when something definite is at stake, the victory is either won, or it is lost; the conduct of individual men, at all events, is overruled by considerations external to themselves which admit of being weighed and calculated. In a war of succession, where the great families were divided in their allegiance, and supported the rival claimants in evenly balanced numbers, the inveteracy of the conflict increased with its duration, and propagated itself from generation to generation. Every family was in blood feud with its neighbour; and children, as they grew to manhood, inherited the duty of revenging their fathers' deaths. No effort of imagination can reproduce to us the state of this country in the fatal years which intervened between the first rising of the Duke of York and the battle of Bosworth; and experience too truly convinced Henry VII. that the war had ceased only from general exhaustion, and not because there was no will to continue it. The first Tudor breathed an atmosphere of suspended insurrection, and only when we remember the probable effect upon his mind of the constant dread of an explosion, can we excuse or understand, in a prince not generally cruel, the execution of the Earl of Warwick. The danger of a bloody revolution may present an act of arbitrary or cowardly tyranny in the light of a public duty. Fifty years of settled government, however, had not been without their effects. The country had collected itself; the feuds of the families had been chastened, if they had not been subdued; while the increase of wealth and material prosperity had brought out into obvious prominence those advantages of peace which a hot-spirited people, antecedent to experience, had not anticipated, and had not been able to appreciate. They were better fed, better cared for, more justly governed than they had ever been before; and though abundance of unruly tempers remained, yet the wiser portion of the nation, looking back from their new vantage-ground, were able to recognise the past in its true hatefulness. Thenceforward a war of succession was the predominating terror with English statesmen, and the safe establishment of the reigning family bore a degree of importance which it is possible that their fears exaggerated, yet which in fact was the determining principle of their action.
