II. So long as the trading inhabitants owned the jurisdiction of the town courts their presence brought no serious difficulty to the ruling authorities. But within the town walls there were other groups of men who lay beyond this jurisdiction, and held an ambiguous position which was the source of many a quarrel for ascendency and many a struggle for license in the course of the fifteenth century. These were the tenants and dependants of bishop or abbot, of some lay lord, or of the king’s castle—men who lived within the liberties of the borough and who had the right of trading in the town, but who were bound to do suit and service at the courts of their own special lord.[364] To some extent they were forced to recognize the mayor’s authority, since their rights of trade were guaranteed by his protection, and since he yearly reminded them of his power to levy taxes on all property within the liberties of the borough. But their obedience was grudging and their loyalty was cold. The mayor could not awe them by a summons to his court, or enforce his demands with threat of pains and penalties; he could scarcely terrify them into submission with his sergeant and a few constables. By degrees, it is true, the tenants of the king’s castle or of feudal lords became merged in the general body of the inhabitants. But the tenants of ecclesiastical estates[365] were maintained by lords who were bound by every tradition of their order never to yield up the least jot of authority to the secular power, and least of all to the secular power as represented by groups of upstart drapers and fishmongers and weavers whose humble shops and booths leaned against the walls of the abbey or the priory, and whose pretensions, loud and noisy though they might be, were perhaps a century or so old at the best. The ecclesiastical tenants therefore remained everywhere an alien body, no true partakers in the life of the town, and when supported by a powerful bishop or abbot determined to crush the pretensions of a struggling borough they proved a serious danger to municipal unity, and one which the authorities found themselves powerless to conquer till the Reformation settled the question for ever.
