Watching my cat look out the window and this random thought pops in my head: former 19th century empires–France, Germany and England for example–are the friendliest states in Europe to the idea of multiculturalism.
There are, of course, people in these countries who fear diversity; however, the majority of their populations are cosmopolitan in their outlook. Interestingly, Hungary and Poland–both countries occupied by outsiders throughout the 19th century–are the most resistant to immigration and the most cloistered. So, in something of an ironic twist, we have the countries which robbed the identity of nations 150 years ago now embracing those identities; and those states that had their identities robbed are the most reluctant to embrace diversity.
There appears to be a correlation, however strong or weak, between an imperial past and a multicultural present.
