|Sorbia during Europeada 2012 in Sorbia|
Sorbia is NOT the same as Serbia ! Sorbia is a cultural minority in the very East of Germany. There are about 60,000 Sorbs in Germany and they came and settled in the Eastern parts of Brandenburg and Saxony during the migration period between 400 and 800 AD. They are still living in those areas and have a strong cultural identity. This includes their own flag, national anthem and language (Srbja is the Sorbian word for Sorbia btw.). With Stanislaw Tillich Saxony is even ruled by a Sorb.
The capital of the Sorbian area (Bautzen) does have a bilingual town sign, which you can see in the picture below.
They "just" offer a cheap version of this shirt, though. If you are interested in this shirt (which was produced for the player) you could try your luck contacting the shop on your own (or ask me ;) )
