Petroșani

Petroșani (Romanian pronunciation: [petroˈʃanʲ]; Hungarian: Petrozsény; German: Petroschen) is a city in Hunedoara County, Transylvania, Romania, with a population of 31,044 as of 2021.

After Romania joined the Allies of World War I in 1916, Romanian troops attacked the town during the Battle of Transylvania.

The Romanian occupation, however, did not last long: the united Austro-Hungarian and German troops regained control of the town shortly, in which guerrilla warfare, led by the local Viktor Maderspach, played an important role.

The town officially became part of the territory ceded to the Kingdom of Romania in June 1920 under the terms of the Treaty of Trianon.

[5] At the 2002 census, 83.3% of the city's inhabitants were Romanian Orthodox, 7.2% Roman Catholic, 3.7% Reformed, 2.2% Pentecostal, 0.8% Greek-Catholic, and 0.9% belonged to another religion.
