It is now that the period begins which William of Newburgh likens to the days when there was no king in Israel, but every man did what was right in his own eyes, nay, not what was right, but what was wrong also, for every lord was king and tyrant in his own house. Castles innumerable sprang up, and as fast as they were built they were filled with devils; each lord judged and taxed and coined. The feudal spirit of disintegration had for once its full play. Even party union was at an end, and every baron fought on his own behalf. Feudalism had its day, and the completeness of its triumph ensured its fall. [Sidenote: Stephen taken prisoner, 1141. ] [Sidenote: Election of Matilda. ] All this was not realized at once. The new year 1141 found Stephen besieging Lincoln, which was defended by Ranulf, earl of Chester, and Robert of Gloucester. Stephen had not yet been defeated in the field, and he had still by his side a considerable body of barons, though none so great as the almost independent earl whom he was attacking. Now, however, he was outmatched or out-generaled. After a struggle marked chiefly by his own valiant exploits he was taken prisoner, and sent to the empress by her brother as a great prize. The battle of Lincoln was fought on February 2, and a week after Easter, in a great council of bishops, barons, and abbots, Matilda, the empress of the Romans, was elected Lady of England at Winchester. This assembly was, it must be allowed, mainly clerical; but there is no doubt that it represented the wishes of a great part of the barons, who, so far as they were willing to have a king or queen at all, preferred Matilda to Stephen. Henry of Winchester, however, took advantage of the opportunity to make somewhat extravagant claims on behalf of his order, declaring that the clergy had the right to elect the sovereign, and actually carrying out the ceremony of election. The citizens of London pleaded hard for the release of Stephen, whom they, six years before, had elected with scarcely less audacious assumption, but in vain. Henry was now at the crest of the wave, and he saw the triumph of the Church in the humiliation of his brother. War was the great trial by combat ordained between kings. Stephen had failed in that ordeal; judgment of God was declared against him; like Saul he was found wanting. [Sidenote: Purpose of the barons. ]
