The international position of the infidel power was an anomalous one. Almost every pope tried to revive the crusading spirit against the arch-enemy of Christ, and the greatest epic poet of the sixteenth century chose for his subject the Delivery of Jerusalem in a holy war. On the other hand the Most Christian King found no difficulty in making alliances with the Sublime Porte, and the same course was advocated, though not adopted, by some of the Protestant states of Germany. Finally, that champion of the church, Philip {450} II, for the first time in the history of his country, [Sidenote: 1580] made a peace with the infidel Sultan recognizing his right to exist in the society of nations.
The sixteenth century, which in so much else marked a transition from medieval to modern times, in this also saw the turning-point of events, inasmuch as the tide drawn by the Half Moon to its flood about 1529, from that time onwards has steadily, if very slowly, ebbed.

CHAPTER X
SOCIAL CONDITIONS
SECTION 1. POPULATION
[Sidenote: Unity of civilized world]
Political history is that of the state; economic and intellectual history that of a different group. In modern times this group includes all civilized nations. Even in political history there are many striking parallels, but in social development and in culture the recent evolution of civilized peoples has been nearly identical. This fundamental unity of the nations has grown stronger with the centuries on account of improving methods of transport and communication. Formally it might seem that in the Middle Ages the white nations were more closely bound together than they are now. They had one church, a nearly identical jurisprudence, one great literature and one language for the educated classes; they even inherited from Rome the ideal of a single world-state. But if the growth of national pride, the division of the church and the rise of modern languages and literatures have been centrifugal forces, they have been outweighed by the advent of new influences tending to bind all peoples together. The place of a single church is taken by a common point of view, the scientific; the place of Latin as a medium of learning has been taken by English, French, and German, each one more widely known to those to whom it is not native now than ever was Latin in the earlier centuries. The fruits of discovery are common to all nations, who now live under similar conditions, reading the same books and (under different names) the same newspapers, doing the same {452} business and enjoying the same luxuries in the same manner. Even in matters of government we are visibly approaching the perhaps distant but apparently certain goal of a single world-state.
