Unirea, previously Vințu de Sus (, ), is a commune located in the north-east of Alba County, Transylvania, Romania. It is composed of six villages: Ciugudu de Jos (Alfüged), Ciugudu de Sus (Felfüged), Dumbrava (Dombró), Inoc (Inakfalva), Măhăceni (Aranyosmohács) and Unirea. Geography Unirea is located on the Mureș River, in the north-east corner of Alba County, approximately 50 km from the county capital, Alba Iulia, and 20 km from the town of Turda, on the Romanian National Road DN1. The commune is bordered by Cluj County in the north and west, the town of Ocna Mureș in the east, and the commune of Mirăslău in the south. History From the late 13th century until 1876 the centre of today's commune was the administrative centre of the Aranyosszék region of Transylvania. In 1876, when the administrative system of the Kingdom of Hungary was reorganised, it became part of Torda-Aranyos county. After the Union of Transylvania with Romania in 1918, the commune became part of Turda County. Since 1968, when the latest administrative organisation in Romania was adopted, Unirea has been part of Alba County. Name The first documentary evidence of the commune dates from 1219 under the names Vynch superior, terra Wynchy, Oronos Winch, and Oranas Wincz. The Romanian version of the name, Vințu de Sus, became official only after the Union of Transylvania with Romania in 1918. Other early Romanian names were Vinț and Felvinț. In 1925, the official name was changed to Unirea referring to the unification of Vințu de Sus and Vereșmart. The Hungarian version of the name, Felvinc was mentioned for the first time in a document from 1291 in the form Felvynch. As part of the Kingdom of Hungary, the Hungarian version was consistently used throughout the Middle Ages, with the mention that sometimes the form Aranyosvinc and Felső-Vincz were also used. In the 18th and the 19th century, the official name was "Oppidum Felvincz" (from 1760) or "Felvincz mezőváros" (from 1713). The German version of the name, Oberwintz, dates to 1532. All the three names are related to each other meaning Upper Vinc/Vințu/Wintz in English. The name refers to the medieval patron of the Catholic parish, Saint Vincentius because a 13th-century document calls the town Sanctus Vincentius. Demographics The 2011 census recorded that 4,574 people were living at the time in the commune, of whom 3,233 (70.7%) Romanians, 820 (17.9%) Roma and 514 (11.2%) Hungarians.
