Ślężanie
From Wikipedia, the free encyclopedia
Ślężanie was a tribe of West Slavs, specifically of the Lechitic/Polish tribes/Silesian tribes groups, inhabiting territories of Lower Silesia, near Mount Ślęża mountain and Ślęza river up to the area of modern city of Wrocław. The name of the region Silesia comes from their language and tribe name.[citation needed]
The 'Bavarian Geographer' mentions they had 15 settlements, or gróds. The Prague document refers to them with the alternative name Zlasane.
In their early period, they were subordinate to Great Moravia. From 990, they came under the sphere of influence of Mieszko I, first ruler of Kingdom of Poland. Since then, they have been assimilated into Silesian society.
