Throughout the Middle Ages it was customary for people of all classes and background to travel, often widely. The households of the upper classes and royal courts moved between manors and estates; the demands of diplomacy, war and crusades took men to distant countries; priests travelled between churches, monasteries and formed emissaries to Rome; people of all classes went on pilgrimage, or travelled to find work; others travelled as a pastime. Most people undertook small journeys on foot and hired horses for longer journeys. For the upper classes, travel was accompanied by a great deal of pomp and display, with fine horses, large retinues and magnificent cavalcades in order to display their wealth as well as to ensure personal comfort. For example, in 1445, the English royal household contained 60 horses in the king's stable and 186 kept for "chariots" (carriages) and carts.
