Sorbian languages
The Congress of Vienna, in 1815, gave part of Upper Lusatia to Saxony, but most of Lusatia to Prussia. More and more bans on the use of Sorbian languages appeared from then until 1835 in Saxony and Prussia; emigration of the Sorbs, mainly to the town of Serbin in Texas and to Australia, increased. In 1848, 5000 Sorbs signed a petition to the Saxon Government, in which they demanded equality for the Sorbian language with the German one in churches, courts, schools and Government departments. From 1871 the whole of Lusatia became a part of united Germany and was divided between two parts; Prussia (Silesia and Brandenburg), and Saxony.
