Poles
Polish people are the sixth largest national group in the European Union. Estimates vary depending on source, though available data suggest a total number of around 60 million people worldwide (with roughly 21 million living outside of Poland, many of whom are not of Polish ethnicity, but Polish nationals). There are almost 38 million Poles in Poland alone. There are also Polish minorities in the surrounding countries including (Germany), and indigenous minorities in the Czech Republic, Hungary, Slovakia, northern and eastern Lithuania, western Ukraine, and western Belarus. There are some smaller indigenous minorities in nearby countries such as Moldova. There is also a Polish minority in Russia which includes indigenous Poles as well as those forcibly deported during and after World War II; the total number of Poles in what was the former Soviet Union is estimated at up to 3 million.
Poland
Following the formation of the Polish-Lithuanian Commonwealth in 1569, the country over the next two centuries contained many languages, cultures and religions. The Commonwealth was primarily composed of three nations: Poles, Lithuanians, and Ruthenians (Ukrainians and Belarusians) — there were also sizable minorities of groups such as Germans, Jews, Latvians, Scots, Armenians, Mennonites and Tatars. After the partitions of Poland at the end of the 18th century, the bulk of the ethnic Polish population was primarily located in Congress Poland, and in the Galicia and Poznań provinces. When Poland regained its independence in 1918, Poles constituted the majority of the population in the country, during the interwar period, with sizable Ukrainian, Belarusian, Jewish and German minorities.
