As with the internment camps of all countries for those considered unreliable during wartime, the Austro-Hungarian authorities imprisoned Carpatho-Rusyns and Ukrainian Russophiles, as well as other Ukrainians and Lemkos from Galicia and Bukovina. The first group of prisoners was interned in Talerhof on September 4, 1914.
A Russian historian argues that these people were punished for their loyalty to the Russian language and culture, saying that the people who had renounced the Russian language and identified themselves as Ukrainians were released from the camp.  Over twenty thousand people were arrested and placed in the Austrian internment camp in Talerhof. (Another internment camp for supporters of Russia was the fortress at Terezín, now in the Czech Republic.)
Until the winter 1915, there were no barracks in Talerhof. Prisoners slept on the ground in the open-air during rain and frost. According to U.S. Congressman Medill McCormick, prisoners were beaten and tortured. On November 9, 1914 official report of field marshal Schleer said there were 5,700 Carpatho-Rusyns, Lemkos, and Ukrainians in Talerhof. In all, 20 thousand people were prisoners of Talerhof from September 4, 1914 to May 10, 1917. The camp was closed by Emperor Charles I of Austria, after the first 6 months of his reign.
Tens of thousands of Ukrainians and Lemkos were victims of reprisals which carried out by the Austro-Hungarian authorities in Galicia during World War I.
The camp site is now located at the Graz Airport.
