I'm having a bit of a hard time finding information about this town.
Whatever help anyone can give me is welcome.
Thanks in advance!
The very same.
My game is set in 1156 though, and I'm not even sure who claimed ownership to the city then, and I'm thinking they spoke Old Polish, but possibly some Middle High German as well.
And was the town claimed by the Duke of Poland (Duke of Krakow) or someone else?
Pretty easy combination of
legnica.um.gov.pl/en/site/miasto/historia
and
en.wikipedia.org/wiki/Boles%C5%82aw_IV_the_Curly
tells me it was claimed by the Duke of Masovia, who also happened to be High Duke of all Poland at the time - until 1173.
Here is some background for the period of Polish rule around that time period.

From the link in the above article to Boleslaw III, you can read more in this article...
en.wikipedia.org/wiki/Boles%C5%82aw_III_Wrymouth
and here is an article detailing the fragmentation of rule and the troubles that ensued...
en.wikipedia.org/wiki/Fragmentat ... 38-1295.29
(scroll down to "Fragmentation and Invasion 1138-1295")
Hope that helps. 
Wolf, This article seems to indicate a different final authority than ol Curly (typical of convoluted European histories)...
BoXer, aren't you off by a century in that last article?
And I would tend to trust a .gov.pl site in polish matters
DOH! You're right, so much for my concentration roll on that one! 
This was great, thanks!
