CLASSES England disappeared toward the end of the fifteenth century, dwelt apart for fear of iniecting the healthy. The four hospitals outside the four main entrances to the city served to keep the disease isolated. York received from time to time a large number and a great diversity of visitors. Distinguished visitors usually received gifts from the Corporation. Kings, queens, and full court and retinue came, and sometimes the entire houses of Parliament. At such times great crowds of nobles, spiritual lords, commoners, officers, military and civil, thronged the city and taxed its accommodation. On such an occasion as Richard IlL's attendance at the Minster for mass, or the visit of Henry V., the narrow streets were packed to suffocation with people assembled to watch the processions of gorgeously arrayed sovereigns, princes, peers, ecclesiastics, soldiers, and distinguished commoners. The Duke of Gloucester, afterwards Richard III., was very popular in the North, especially in York, where he was received (as in 1483) with magnificence and festivity. The north was loyal to him and gave him much support in his political schemes. The visits of the royal judges of assize, of sailors and pilgrims, have already been mentioned. Pedlars, who were active nomad tradesmen, were always to be found in town and country dealing in their small wares. I^ast, and some of the unhappiest, among the types of people to be found in a mediaeval city were serfs who had absconded from the lands or the service to which they were bound. They sometimes fled to a city for the security it afforded. Serfdom, however, was rapidly disappearing.
