Historically, especially during the time of the Polish-Lithuanian Commonwealth, Poland was a very ethnically diverse country, but as a result of the German-Nazi Holocaust, significantly altered borders, and deportations ordered by Soviet authorities, the population of post-World War II Poland became nearly entirely ethnically homogeneous.
Nowadays, thanks to our membership in the European Union, continuous development of technology, globalization and change of outlook on the world, the picture of the Polish population is becoming more diverse again. Additionally, Greater Poland Voivodiship (Wielkopolska) is an area without natural borders, that has long been a crossroads for important commerce routes and people flow. It does not come as a surprise, that some of them settled in the area, enhancing the history and culture of the area.
