History of European Tourism

Wealthy people have always traveled to distant parts of the world to see great buildings or other works of art, to learn new languages, to experience new cultures, or to taste new cuisine. As long ago as the time of the Roman Republic places such as Baiae were popular coastal resorts for the rich.
The terms tourist and tourism were first used as official terms in 1937 by the League of Nations. Tourism was defined as people traveling abroad for periods of over 24 hours.
The history of European tourism can perhaps be said to originate with the medieval pilgrimage. Although undertaken primarily for religious reasons, the pilgrims in the Canterbury Tales quite clearly saw the experience as a kind of holiday (the term itself being derived from the 'holy day' and its associated leisure activities). Pilgrimages created a variety of tourist aspects that still exist - bringing back souvenirs, obtaining credit with foreign banks (in medieval times utilizing international networks established by Jews and Lombards), and making use of space available on existing forms of transport (such as the use of medieval English wine ships bound for Vigo by pilgrims to Santiago De Compostela). Pilgrimages are still important in modern tourism - such as to Lourdes or Knock in Ireland. But there are modern equivalents - Graceland and the grave of Jim Morrison in Père Lachaise Cemetery.
