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.
