800.000 in romania

500.000 in bulgaria

Answer 1

Because hundreds of years ago there was a gradual migration of these peoples towards the West.  Just as migration of other peoples occurred in other countries eg Slavs moved from Russia and populated the Balkans; Germans and Danes migrated to England.  Over the history of humankind, just about every country in the world has accommodated a mass migration of people of different nationalities.
