The Silesians (Polish: Ślężanie) were a tribe of West Slavs, specifically of the Lechitic/Polish group, inhabiting territories of Lower Silesia, near Ślęża mountain and Ślęza river,[1] on both banks of the Oder,[2] up to the area of modern city of Wrocław.
Other, more minor, Silesian tribes of the time included the Golensizi, Trzebowianie (who might have actually been part of the Ślężanie), Bobrzanie (who were probably subjects of the Dziadoszanie) and the Głubczyce, further to the south.
[1] A long fortified wall, strengthened by numerous moats, stretched from the present day town of Jelenia Góra to Krosno Odrzańskie, and along both sides of the Bobr river.
However, the wall most likely served a solely defensive purpose, most likely as a bulwark against raiding parties of the neighboring Polabian Slavs as none of the Polish tribes yet shared direct borders with Germanic states at the time.
[8] Over time, the Ślężanie, along with the other Silesian tribes, as well as the Vistulans, Pomeranians, Lendians, Masovians and the Polans mixed and became part of the Polish state.
