It is estimated that over half a million Polish people have come to work in the United Kingdom from Poland.
Since 2011, Poles have been able to work freely throughout the EU and not just in the United Kingdom, Ireland and Sweden where they have had full working rights since Poland's EU accession in 2004.
Influences were also conveyed by immigrants (Hungarian, Sloval, Czech, Jewish, German and Dutch), political alliances (with Lithuania, Hungary, Saxony, France and Sweden), conquests of the Polish-Lithuanian state (Ukraine, Belarus, Moldova, Romania and Latvia) and conquerors of the Polish lands (the Russian Empire, Kingdom of Prussia and the Habsburg monarchy, later to be known as the Austrian Empire or Austria-Hungary).
For other uses, see Poles (disambiguation).; singular masculine: Polak, singular feminine: Polka), commonly referred to as the Polish people, are a nation and West Slavic ethnic group native to Poland who share a common ancestry, culture, history and are native speakers of the Polish language.The concept which has become known as the Piast Idea, the chief proponent of which was Jan Ludwik Popławski, is based on the statement that the Piast homeland was inhabited by so-called "native" aboriginal Slavs and Slavonic Poles since time immemorial and only later was "infiltrated" by "alien" Celts, Germans, Turkic peoples and others.After 1945 the so-called "autochthonous" or "aboriginal" school of Polish prehistory received official backing in Poland and a considerable degree of popular support.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 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.
