>>11904119just look at the former yugoslavia, muslims were a minority in the country and just out bred everyone else to be the majority in enclaves, or parts of the country.
interesting case as they didnt want to categorize people whose religion is muslim as turkish or arab so they just put them in a muslim category.
Anyways, Yugoslavia version 1 started 1922 i think?, version 2 started in 1945, first civil war with muslims at around 45% population of a region started around 1991? 2nd civil war with muslims and a part of the country at around 68% population started in 1996.
Both resulted in new micro nations being formed.
So using this simple use case, 2068 will be the first civil war in some part of europe demanding to be independent because they are muslim once that country or region hits close to 50% muslim population. Followed on by other parts of europe once parts of it hit over 50% a few years later and snowball from there.
