Reghin (ˈreɡin; Szászrégen, ˈsaːsreːɡɛn or Régen; (Sächsisch) Regen or Sächsisch-Reen; Transylvanian Saxon: Reen) is a city in Mureș County, Transylvania, central Romania, on the Mureș River. As of 2011, it had a population of 33,281.
Reghin lies north-northeast of Târgu Mureș, extending on both shores of the river Mureș, at the confluence with the Gurghiu River. It was created by the 1926 union of the German-inhabited (formerly Szászrégen) and the Hungarian-inhabited (formerly Magyarrégen) city, and later joined with the two smaller communities of Apalina (Hungarian: Abafája; German: Bendorf) and Iernuțeni (Hungarian: Radnótfája; German: Etschdorf), added in 1956. Formally, the latter two are separate villages administered by the city.
The city is on the Târgu Mureș–Deda–Gheorgheni Romanian Railways line 405.
Reghin was first mentioned in 1228 in a charter of Hungarian King Andrew II as Regun – however, evidence of its strategic location and defence system suggests that the town might have been considerably older, possibly founded by Ladislaus I.
Despite the devastations of the city during the Mongol invasion (1241) and during the Tatar and Cuman incursions (1285), the town developed rapidly: already in the second half of the 13th century the city was the residence and power centre of the families Tomaj and Kacsik, to whom the nearby lands were awarded by the Hungarian Crown. Reghin became a minor ecclesiastical centre in 1330, with the building of the Gothic church (Roman Catholic at the time, it now serves the Protestant community) in the German part of the city; it is still the largest church in the area, and hosts the oldest Medieval Latin inscription of any church in Transylvania. The Hungarian part of the city has an even older church, initially built in the Romanesque style.
At the beginning of the 15th century the settlement gained city rights, and, from 1427, the right to hold fairs. In the 16th and 17th century Reghin was devastated by Habsburg and Ottoman troops on several occasions. It burned to the ground in 1848.
