Indirectly, the long wars occasioned by the personal rivalry of Charles and Francis had other results than Habsburg predominance in Italy and French expansion towards the Rhine. They preserved a "balance of power" and prevented the incorporation of the French monarchy into an obsolescent empire. They rendered easier the rise of the Ottoman power in eastern Europe; and French alliance with the Turks gave French trade and enterprise a decided lead in the Levant. They also permitted the comparatively free growth of Protestantism in Germany.

More sinister to Charles V than his wars with the French was the advance of the Ottoman Turks. Under their greatest sultan, Suleiman II, the Magnificent (1520-1566), a contemporary of Charles, the Turks were rapidly extending their sway. The Black Sea was practically a Turkish lake; and the whole Euphrates valley, with Bagdad, had fallen into the sultan's power, now established on the Persian Gulf and in control of all of the ancient trade-routes to the East. The northern coasts of Africa from Egypt to Algeria acknowledged the supremacy of Suleiman, whose sea power in the Mediterranean had become a factor to be reckoned with in European politics, threatening not only the islands but the great Christian countries of Italy and Spain. The Venetians were driven from the Morea and from the Ægean Islands; only Cyprus, Crete, and Malta survived in the Mediterranean as outposts of Christendom.
[Sidenote: Suleiman the Magnificent]
Suleiman devoted many years to the extension of his power in Europe, sometimes in alliance with the French king, sometimes upon his own initiative,—and with almost unbroken success. In 1521 he declared war against the king of Hungary on the pretext that he had received no Hungarian congratulations on his accession to the throne. He besieged and captured Belgrade, and in 1526 on the field of Mohács his forces met and overwhelmed the Hungarians, whose king was killed with the flower of the Hungarian chivalry. The battle of Mohács marked the extinction of an independent and united Hungarian state; Ferdinand of Habsburg, brother of Charles V, claimed the kingdom; Suleiman was in actual possession of fully a third of it. The sultan's army carried the war into Austria and in 1529 bombarded and invested Vienna, but so valiant was the resistance offered that after three weeks the siege was abandoned. Twelve years later the greater part of Hungary, including the city of Budapest, became a Turkish province, and in many places churches were turned into mosques. In 1547 Charles V and Ferdinand were compelled to recognize the Turkish conquests in Hungary, and the latter agreed to pay the sultan an annual tribute of 30,000 ducats. Suleiman not only thwarted every attempt of his rivals to recover their territories, but remained throughout his life a constant menace to the security of the hereditary dominions of the Habsburgs.

German Monarchy]
At the very time when Charles V was encountering these grave troubles in administering his scattered hereditary possessions and in waging war now with the French and now with the Mohammedans, he likewise was saddled with problems peculiar to the government of his empire. Had he been able to devote all his talent and energy to the domestic affairs of the Holy Roman Empire, he might have contributed potently to the establishment of a compact German state. It should be borne in mind that when Charles V was elected emperor in 1519 the Holy Roman Empire was virtually restricted to German-speaking peoples, and that the national unifications of England, France, and Spain, already far advanced, pointed the path to a similar political evolution for Germany. Why should not a modern German national state have been created coextensive with the medieval empire, a state which would have included not only the twentieth-century German Empire but Austria, Holland, and Belgium, and which, stretching from the Baltic to the Adriatic and from the English Channel to the Vistula, would have dominated the continent of Europe throughout the whole modern era? There were certainly grave difficulties in the way, but grave difficulties had also been encountered in consolidating France or Spain, and the difference was rather of degree than of kind. In every other case a strong monarch had overcome feudal princes and ambitious nobles, had deprived cities of many of their liberties, had trampled upon, or tampered with, the privileges of representative assemblies, and had enforced internal order and security. In every such case the monarch had commanded the support of important popular elements and had directed his major efforts to the realization of national aims.
National patriotism was not altogether lacking among Germans of the sixteenth century. They were conscious of a common language which was already becoming a vehicle of literary expression. They were conscious of a common tradition and of a common nationality. They recognized, in many cases, the absurdly antiquated character of their political institutions and ardently longed for reforms. In fact, the trouble with the Germans was not so much the lack of thought about political reform as the actual conflicts between various groups concerning the method and goal of reform. Germans despised the Holy Roman Empire, much as Frenchmen abhorred the memory of feudal society; but Germans were not as unanimous as Frenchmen in advocating the establishment of a strong national monarchy. In Germany were princes, free cities, and knights,— all nationalistic after a fashion, but all quarreling with each other and with their nominal sovereign.
[Sidenote: Charles V bent on Strengthening Monarchical Power though not on a National Basis]
The emperors themselves were the only sincere and consistent champions of centralized monarchical power, but the emperors were probably less patriotic than any one else in the Holy Roman Empire. Charles V would never abandon his pretensions to world power in order to become a strong monarch over a single nation. Early in his reign he declared that "no monarchy was comparable though not to the Roman Empire. This the whole world had once obeyed, and Christ Himself had paid it honor and obedience. Unfortunately it was now only a shadow of what it had been, but he hoped, with the help of those powerful countries and alliances which God had granted him, to raise it to its ancient glory." Charles V labored for an increase of personal power not only in Germany but also in the Netherlands, in Spain, and in Italy; and with the vast imperial ambition of Charles the ideal of creating a national monarchy on a strictly German basis was in sharp conflict. Charles V could not, certainly would not, pose simply as a German king—a national leader.
