The root of the whole social system is to be found in the Mark, which is a division of the territory held jointly by a certain number of freemen for the purposes of cultivation, mutual help and defence. The community began as a kinship or tribe, but even when the original blood ties were lost sight of and modified by the influx of heterogeneous elements, the community remained self-sufficient and isolated. The whole fabric of society rested on property in land: as its political divisions were based on the possession of common lands, even so the rank of an individual depended entirely on his holding. The Teutonic world had no idea of a citizen severed from the soil. The curious fact that the normal holding, the hide, was equal all over England (33-1/2 acres) can be explained only by its origin; it came full-formed from Germany and remained unchanged in spite of all diversities of geographical and economical conditions. The transformation of medieval society is, for Kemble, intimately connected with the forms of ownership in land. The scanty population of ancient times had divided only a very small part of the country into separate holdings. The rest remained in the hands of the people to supply the wants of coming generations. The great turn towards feudalism was given by the fact that this reserve-fund lapsed into the hands of a few magnates: the mass of free people being deprived of its natural sphere of expansion was forced to seek its subsistence at the hands of private lords (loaf-givers). From the point of view of personal status the same process appears in the decrease of freedom among the people and in the increase of the so-called Gesíð. According to Teutonic principles a man is free only if he has land to feed upon, strength to work, and arms to defend himself. The landless man is unfree; and so is the Gesíðcundman, the follower, however strong and wealthy he may be through his chief's grace. The contrast between the free ceorls tilling their own land and the band of military followers, who are always considered as personally dependent--this contrast is a marked one. From the first this military following had played an important part in German history. Most raids and invasions had been its work, and sometimes whole tribes were attracted into its organisation, but during the first period of Saxon history the free people were sufficiently strong to hold down the power of military chiefs within certain bounds. Not so in later development. With the growth of population, of inequalities, of social competition, the relations of dependency are seen constantly gaining on the field of freedom. The spread of commendation leads not only to a change in the distribution of ranks, but to a dismemberment of political power, to all kinds of franchises and private encroachments on the State.
