To be fair, it is only natural: Portuguese itself only came to be because the Roman Empire conquered the Lusitan land [1], a lot of English comes from Norman French from the Norman conquest [2], the Americas didn't speak European languages until 500 years ago or so, etc.

If you give enough time, all languages will change, and some of them because of major political changes/conquests
