Now it was towards the Roman Empire that the hopes and sympathies of these political speculators as well as of the jurists and poets of the fourteenth and fifteenth centuries were constantly directed. The cause may be gathered from the circumstances of the time. The most remarkable event in the history of the last three hundred years had been the formation of nationalities, each distinguished by a peculiar language and character, and by steadily increasing differences of habits and institutions. And as upon this national basis there had been in most cases established strong monarchies, Europe was broken up into disconnected bodies, and the cherished scheme of a united Christian state appeared less likely than ever to be realized. Nor was this all. Sometimes through race-hatred, more often by the jealousy and ambition of their sovereigns, these countries were constantly involved in war with one another, violating on a larger scale and with more destructive results than in time past the peace of the religious community; while each of them was at the same time torn within by frequent insurrections, and desolated by long and bloody civil wars. The new nationalities were too fully formed to allow the hope that by their extinction a remedy might be applied to these evils. They had grown up in spite of the Empire and the Church, and were not likely to yield in their strength what they had won in their weakness. But it still appeared possible to soften, if not to overcome, their antagonism. What might not be looked for from the erection of a presiding power common to all Europe, a power which, while it should oversee the internal concerns of each country, not dethroning the king, but treating him as an hereditary viceroy, should be more especially charged to prevent strife between kingdoms, and to maintain the public order of Europe by being not only the fountain of international law, but also the judge in its causes and the enforcer of its sentences?
