After centuries of relative ethnic diversity, the population of modern Poland has become nearly completely ethnically homogeneous Polish as a result of altered borders and the Nazi German and Soviet or Polish Communist population transfers, expulsions and deportations (from or to Poland) during and after World War II. Ethnic minorities remain in Poland, however, including some newly arrived or increased in number. Ethnic groups include Germans, Ukrainians and Belarusians.
