The limited monarchy of England is a result of the action of two distinct elements, equally necessary for its composition. It is a manifestation of the monarchical power descended both in principle and in particular attributes from the Roman Empire. If this political idea had not been at work the kingdoms of the barbarians would have presented only loose aggregates of separate and self-sufficient political bodies; on the other hand, if this political idea had been supreme, medieval kings would have been absolute. The principles of Teutonic and of Roman polity had to work together, and the result was the medieval State with an absolute king for its centre, and a great independence of local parts. The English system differed from the continental in this way, that in England the free judicial institutions of the localities reacted on the central power, and surrounded it by constitutional limitations, while the Continent had to content itself with estates of a very doubtful standing and future. It is easy to see in this connexion how great an importance we must assign to the constitution of local Courts: the shires, hundreds, and townships are not mere administrative divisions, but political bodies. That the kingdom formed itself on their basis, not as an absolute but as a parliamentary monarchy, must be explained in a great measure by the influence of the Norman Conquest, which led to a closer union of the isolated parts, and to a concentration of local liberty in parliament. But (such is Palgrave's view) the importance of Conquests has been greatly overrated in history. The barbarian invasion did not effect anything like a sudden or complete subversion of things; it left in force and action most of the factors of the preceding period. The passage from one rule to another was particularly easy in England, as most tribes which occupied the island were closely related to each other. Palgrave holds that the Britons, Anglo-Saxons, Danes, and Normans all belong to one and the same Teutonic race. There were, of course (he allows), Celtic elements among the Britons, but the greater part consisted of Belgian Kymrys, whose neighbours and kin are to be found on the Continent as Saxons and Frisians. The conquest of the island by bands of seafaring Saxons did not lead by any means to the wholesale destruction and depopulation which the legendary accounts of the chronicles report. The language of the Britons has not been preserved, but then no more has the Celtic language in Gaul. The Danish and Norman invasions had even less influence on social condition than the Saxon. It is only the Roman occupation that succeeded in introducing into the life of this island important and indestructible traits.
