The men in these towns were, from the very first, more inclined to hold out against an overlord than the men in the villages were. In the first place, their numbers were greater; and then they had more varieties of occupation than the villagers, or, as we may say, had wider interests. In the trading towns, like London and Southampton, they came in contact with traders from other lands, and trade brought them more wealth. They, too, had their folk-moots, and they had more business to transact in them than the country villagers had. They were very particular to keep a tight hold on their rights, and were always on the look-out to gain fresh privileges if they possibly could. The fence or wall, which surrounded the town, was made much stronger than that round the village; and men saw the use now of the thick walls of the old Roman cities which their ancestors had despised, for they had wealth and goods which needed protection. We have seen that the power of the king gradually increased; and, as it did so, the king and the town became more necessary to each other. The town was wealthy; but it could not stand by itself against all the rest of the country. The king had the power of the country at his back, and could protect it if he would. The town had to give something to the king in return for this protection. But we shall presently see more of the relations between king and town. CHAPTER XI In Early Christian Times One great and important factor in the making of Saxon England was Christianity. The first Saxons who came were heathen, and they wiped out the British Christianity, where they settled, as completely as they wiped out Roman civilization. Towards the end of the sixth century Christian missionaries were at work in the north and in the south of what we now call England, and from that time onwards the Church played an important part in the making of the nation. So, side by side with the development and political growth of the country came the spread of Christianity and the organization of the Church. We find that the folk in the Saxon kingdoms, following the lead of their kings, became Christian as a matter of course. Over and over again we find the kings giving up Christianity and going back to paganism, and their people following them, also as a matter of course. The conversion of England took many years to accomplish, and mixed up with the Christianity was much paganism, which was not overcome for many centuries. The dioceses[7] of the early Saxon bishops were, roughly speaking, of the same extent as the early kingdoms, and the bishops and their clergy travelled about as missionaries. [7] A diocese is the district over which a bishop rules.
