The effect of the dispersion of the Jews was to give a peculiar sacredness to the law as the sole heritage of their earlier and happier days. In most of the lands of their dispersion, the Jews dwelt a race apart, separated from the rest of the community by mutual prejudices and antagonisms. The soil on which they dwelt was so far as ultimate overlordship was concerned the land of the stranger, but nevertheless in a very definite and special sense it was the Jews' own land. For it was a land in which the law of the stranger was not the law. The law of the land of their dispersion was not the law of the owner of the soil but the law of the Jews. In this sense the Ghettos of Italy and the Gassen of Germany were not so much Italian and German soil as they were Jewish. As by the modern fiction of extraterritoriality the home of an Ambassador is considered part of his own national territory, so these exclusively Jewish settlements were colonies of Judæa planted on foreign soil. They were separated from the rest of the land by visible or invisible walls, and within these walls, hardly touched by the influences that were at work shaping the life around them, the ancient law of the Jews was preserved and handed down from generation to generation. Hence during the Middle Ages the student of the law became the most important member of the community, and all the energy of the community that was not required to outwit the constant menace of brutal force and religious persecution was devoted to the cultivation of the law and of the literature that it gave rise to. It should be noted, however, that since the beginning of the Talmudic period, the civil law developed in certain directions only, because after all the Jewish people had no land of their own in the usual sense and no central authority and were constantly moving from place to place, always subject to persecution. Some branches of their law were entirely neglected and others abnormally developed. _The Schools of the Law_
