More honourable to Hubert than this almost personal triumph is his administrative work. Of this it will be sufficient to say here, that he had constantly to find large sums of money for the king; that he did so as far as possible by constitutional methods; that in doing so he accustomed the people to make elections and act by representatives; and that he preserved internal order and developed the constructive work of Henry II. Richard's demands for money were heavy, and though Becket had once opposed Henry on a fiscal question, no constitutional resistance had ever yet been made to a tax proposed by the Crown. Now, however, the nation was to receive from the Church its first lesson in the principle that taxes should only be imposed with the consent of those who have to pay them. At an assembly held at Oxford in 1198 the archbishop, on the king's behalf, proposed to the barons and bishops that they should maintain three hundred knights for a year to serve across the sea. Then Hugh of Lincoln answered, that though he had come to England as a stranger, he would maintain the rights of his church, and that though it was bound to do military service within the kingdom, the king could not claim such service beyond the sea, and that he would not contribute to a foreign war. Herbert of Salisbury also spoke to the same effect. Their answers naturally appealed to the interests of the lay barons, and the demand was refused, greatly to the king's annoyance. Hubert's position was not altogether pleasant. The king was always calling on him to find fresh supplies, and he was harassed by a suit brought against him at Rome by his chapter about the college he was building at Lambeth, a subject that belongs to another volume of this series. A serious trouble had also arisen in 1196. The taxes pressed heavily on the lower classes, and a revolt was raised in London, where the richer citizens were accused of throwing the burden of taxation on the poor. The leader of the discontented citizens was a demagogue named William Fitz-Osbert, or William Longbeard, as he was commonly called. Hubert tried to arrest him, but William fled for refuge to the church of St. Mary-le-Bow. By Hubert's order the church was set on fire, and William was smoked out, taken, and hanged. The church belonged to the convent of Christ Church, and the monks, indignant at this breach of sanctuary, complained to Pope Innocent III., who in 1198, wrote to Richard urging him to dismiss his minister, and commanding that for the future bishops and priests should not take part in civil administration. Hubert was therefore compelled to resign the justiciarship.
