WIkipedia - polish culture:
The culture of Poland is closely connected with its intricate thousand-year history.1 Its unique character developed as a result of its geography at the confluence of various European regions. With origins in the culture of the Early Slavs, over time Polish culture has been profoundly influenced by its interweaving ties with the Germanic, Latinate and Byzantine worlds as well as in continual dialog with the many other ethnic groups and minorities living in Poland.2 The people of Poland have traditionally been seen as hospitable to artists from abroad and eager to follow cultural and artistic trends popular in other countries. In the 19th and 20th centuries the Polish focus on cultural advancement often took precedence over political and economic activity. These factors have contributed to the versatile nature of Polish art, with all its complex nuances.2 Nowadays, Poland is a highly developed country that retains its tradition.
