While early travel tended to be slower, more dangerous, and more dominated by trade and migration, cultural and technological advances over many years have tended to mean that travel has become easier and more accessible. Mankind has come a long way in transportation ever since Christopher Columbus sailed to the new world from England in 1492, an expedition which took over 10 weeks to arrive at the final destination; to the present day where anyone can go, buy a plane ticket, and fly like a bird to what is now called The United States of America overnight
While travel in the Middle Ages offered hardships and challenges, it was important to the economy and to society. The wholesale sector depended (for example) on merchants dealing with/through caravan or sea-voyagers, end-user retailing often demanded the services of many itinerant peddlers wandering from village to hamlet, gyrovagues (Wandering Monks) and wandering friars brought theology and pastoral support to neglected areas, travelling minstrels practiced the never-ending tour, and armies ranged far and wide in various crusades and in sundry other wars.
Pilgrimages involved streams of travellers both locally (Canterbury Tales-style) and internationally.
