Especially medieval Western Europe was characterized by a political rule where the highest political authorities constantly changed their whereabouts, bringing with them (the whole or parts of) the country's central government on their journey.
Især Vesteuropa var præget af et politisk styre hvor de højeste politiske myndigheder konstant ændrede bopæl, og også førte med (hele eller store dele af) landets centrale regering på deres rejser.
