The Vereinigte (Union) zu Tamsweg was founded in 1738 by craftsmen from Lungau and has been maintained by workers ever since, thereby making it the oldest existing union in the area around the market town of Tamsweg (Salzburg). Members attend funerals, accompany church processions and hold the Vereinigtenoktav, a week-long festival celebrated every year between January 1 and the first Saturday after Ash Wednesday. In addition to members of the Tamsweg Union, members of confraternities from other federal states attend these festivities.
This associations organizational structure corresponds to those of former confraternities, which were divided into married and single persons. Members of the Tamsweg Union have molded the local populations cultural identity. Their major principles are based on mutual respect and assistance.
