Yes, they are mostly wrong. The five national minority languages were explicitly written into law in 1999. In the same article where you got that quote you'll have read (but failed to mention) that 'A significant immigration to Sweden did not start until after World War I' [1]. Also it is a little... far-fetched... to pull in the fact that Sweden used to be a conquering nation - the period called 'stormaktstiden' [2] (the time of great power) here - as 'proof' that Sweden used to be more diverse. It wasn't Sweden which used to be more diverse, it was just that the Swedish kings had turned their country into a well-oiled military machine which was used to spread Swedish influence and power over a large area. It was actually the fact that Sweden was so homogeneous which made it possible for King Gustav I Vasa to take over from the Roman Catholic church and found the Church of Sweden (in 1536) and use its organisation to help create that well-oiled military machine in the first place.
