Udanin
Udanin is a village in Środa Śląska County, Lower Silesian Voivodeship, in south-western Poland. It is the seat of the administrative district ( gmina) called Gmina Udanin. Prior to 1945 it was in Germany. After World War II the region was placed under Polish administration and ethnically cleansed according to the post-war Potsdam Agreement. The native German populace was expelled and replaced with Poles.
It lies approximately south-west of Środa Śląska, and west of the regional capital Wrocław.
