The Crusading movement failed for many reasons but mainly because the material requirements for sustaining a military and political outpost so far from the heartland of western Europe were not met. But as a component of European culture, the Crusade ideal remained prominent, even in the 15th and 16th centuries, when the powerful Ottoman Empire indeed threatened to sweep over Mediterranean and southeastern Europe. Not until the Treaty of Carlowitz in 1699 was a stable frontier between the Ottoman Empire and the Holy Roman Empire established.
Contempt for Islam and fear of Muslim military power did not, however, prevent a lively and expansive commercial and technological transfer between the two civilizations or between them and the Byzantine Empire. Commercial and intellectual exchanges between Islamic lands and western Europe were considerable. Muslim maritime, agricultural, and technological innovations, as well as much East Asian technology via the Muslim world, made their way to western Europe in one of the largest technology transfers in world history. What Europeans did not invent they readily borrowed and adapted for their own use. Of the three great civilizations of western Eurasia and North Africa, that of Christian Europe began as the least developed in virtually all aspects of material and intellectual culture, well behind the Islamic states and Byzantium. By the end of the 13th century it had begun to pull even, and by the end of the 15th century it had surpassed both. The late 15th-century voyages of discovery were not something new but a more ambitious continuation of the European interest in distant parts of the world. From territorial principalities to territorial monarchies
As a result of the Investiture Controversy of the late 11th and early 12th centuries, the office of emperor lost much of its religious character and retained only a nominal universal preeminence over other rulers, though several 12th- and 13th-century emperors reasserted their authority on the basis of their interpretation of Roman law and energetically applied their lordship and pursued their dynastic interests in Germany and northern Italy. But the struggle over investiture and the reform movement also legitimized all secular authorities, partly on the grounds of their obligation to enforce discipline. The most successful rulers of the 12th and 13th centuries were, first, individual lords who created compact and more intensely governed principalities and, second and most important and enduring, kings who successfully asserted their authority over the princes, often with princely cooperation. The monarchies of England, France, León-Castile, Aragon, Scandinavia, Portugal, and elsewhere all acquired their fundamental shape and character in the 12th century. The office and person of the king
By the 12th century, most European political thinkers agreed that monarchy was the ideal form of governance, since it imitated on earth the model set by God for the universe. It was also the form of government of the ancient Hebrews, the Roman Empire, and the peoples who succeeded Rome after the 4th century. For several centuries, some areas had no monarch, but these were regarded as anomalies. Iceland (until its absorption by Norway in 1262) was governed by an association of free men and heads of households meeting in an annual assembly. Many city-republics in northern Italy—especially Florence, Milan, Genoa, Pisa, and Venice—were in effect independent from the 10th to the 16th century, though they were nominally under the rule of the emperor. Elsewhere in Europe, the prosperous and volatile cities of the Low Countries frequently asserted considerable independence from the counts of Flanders and the dukes of Brabant. In the 15th century the forest cantons of Switzerland won effective independence from their episcopal and lay masters. For the rest of Europe, however, monarchy was both a theoretical norm and a factual reality.
Whereas kings were originally rulers of peoples, from the 11th century they gradually became rulers of peoples in geographic territories, and kingdoms came to designate both ruled peoples and the lands they inhabited. Gradually, inventories of royal resources, royal legislation, and the idea of borders and territorial maps became components of territorial monarchies.
Kings acquired their thrones by inheritance, by election or acclamation (as in the empire), or by conquest. The first two means were considered the most legitimate, unless conquest was carried out at the request or command of a legitimate authority, usually the pope. The king’s position was confirmed by a coronation ceremony, which acknowledged what royal blood claimed: a dynastic right to the throne, borne by a family rather than a designated individual. Inheritance of the throne might involve the successor’s being designated coruler while the previous king still lived (as in France), designation by the will of the predecessor, or simply agreement and acclamation by the most important and powerful royal subjects. When dynasties died out in the male line, the search for a ruler became more complicated; when they died out in the male line and a woman succeeded, there were usually intense debates about the legitimacy of female succession. Liturgical anointing with consecrated oil was accompanied by the ceremonial presentation to the king of objects with symbolic meaning (the crown, the sword of justice, and the helmet, robe, and scepter), by the chanting of prayers dedicated to rulership, and usually by an oath, in which the king swore to protect the church, the weak, and the peace of his kingdom, to administer justice, and to defend the kingdom against its (and his) enemies.
From the very beginning of European history, kings had responsibilities as well as rights and powers. Kings who were thought to have violated their oaths might be considered tyrants or incompetents, and a number of kings were deposed by local factions or papal command, especially in the 13th and 14th centuries. Depositions also required ceremonies that reversed the coronation liturgy. Instruments of royal governance
Kings ruled through their courts, which were gradually transformed from private households into elaborate bureaucracies. Royal religious needs were served by royal chapels—whose personnel often became bishops in the kingdom—and by clerical chancellors, who were responsible for issuing and sealing royal documents. Royal chanceries, financial offices, and law courts became specialized institutions during the 12th century. They recruited people of skill as well as of respectable birth, and they established programs to ensure uniformity and norms of professional competence, goals that were increasingly aided by the education offered by the new universities.
In some circumstances, kings were expected to seek and follow the advice of the most important men in their kingdoms, and these gatherings were formalized after the 12th century. Kings also sometimes convened larger assemblies of lower-ranking subjects in order to issue their commands or urge approval of financial demands. As kings grew stronger and their bureaucracies more articulated, their costs, particularly for war, also increased. Greater financial needs often determined a king’s use of representative institutions in order to gain widespread acceptance of new direct or indirect taxation.
These assemblies developed differently in different kingdoms. In England the first Parliaments were held in the late 13th century, though they were not powerful institutions until the 16th century. In France the Parlement developed into a royal law court, while the intermittent meetings of the Estates-General (a representative assembly of the three orders of society) served as an instrument of consultation and communication for the kings. Across Europe these representative assemblies were composed differently, functioned differently, and possessed different degrees of influence on the ruler and the rest of the kingdom. Their later role as essential and powerful components of government began only in the 16th and 17th centuries.
