Turda

Milliarium of Aiton, the oldest known epigraphical attestation of Potaissa – a copy erected in June 1993 in front of the Turda Post Office

There is evidence of human settlement in the area dating to the Middle Paleolithic, some 60,000 years ago.[4] The Dacians established a town that Ptolemy in his Geography calls Patreuissa, which is probably a corruption of Patavissa or Potaissa, the latter being more common. It was conquered by the Romans, who kept the name Potaissa, between AD 101 and 106, during the rule of Trajan, together with parts of Decebal's Dacia.[5]

The name Potaissa is first recorded on a Roman milliarium discovered in 1758 in the nearby Aiton commune.[6]

Milliarium of Aiton is an ancient Roman milestone dating from 108 AD, shortly after the Roman conquest of Dacia, and showing the construction of the road from Potaissa to Napoca, by demand of the Emperor Trajan. It indicates the distance of 10,000 feet (3,000 m) (P.M.X.) to Potaissa. This is the first epigraphical attestation of the settlements of Potaissa and Napoca in Roman Dacia.

The complete inscription is: "Imp(erator)/ Caesar Nerva/ Traianus Aug(ustus)/ Germ(anicus) Dacicus/ pontif(ex) maxim(us)/ (sic) pot(estate) XII co(n)s(ul) V/ imp(erator) VI p(ater) p(atriae) fecit/ per coh(ortem) I Fl(aviam) Vlp(iam)/ Hisp(anam) mil(liariam) c(ivium) R(omanorum) eq(uitatam)/ a Potaissa Napo/cam / m(ilia) p(assuum) X". It was recorded in the Corpus Inscriptionum Latinarum, vol.III, the 1627, Berlin, 1863.

This milliarium is an attestation of the road known to be built by Cohors I Hispanorum miliaria.[7]

The castrum established was named Potaissa too and became a municipium, then a colonia. Potaissa was the basecamp of the Legio V Macedonica from 166 to 274.

The Potaissa salt mines were worked in the area since prehistoric times.

After the Hungarian conquest, the Turda salt mines were first mentioned in 1075. They were closed in 1932 but have recently been reopened for tourism.

Saxons settled in the area in the 12th century. The town was destroyed during the Tartar invasion in 1241–1242. Andrew III of Hungary gave royal privileges to the settlement. These privileges were later confirmed by the Angevins of Hungary.

The Hungarian Diet was held here in 1467, by Matthias Corvinus. Later, in the 16th century, Turda was often the residence of the Transylvanian Diet, too. After the Battle of Mohács, the city became part of the Eastern Hungarian Kingdom and since 1570 the Principality of Transylvania. The 1558 Diet of Turda declared free practice of both the Catholic and Lutheran religions. In 1563 the Diet also accepted the Calvinist religion, and in 1568 it extended freedom to all religions, declaring that "It is not allowed to anybody to intimidate anybody with captivity or expelling for his religion" – a freedom unusual in medieval Europe. This Edict of Turda is the first attempt at legislating general religious freedom in Christian Europe (though its legal effectiveness was limited).

In 1609 Gabriel Báthori granted new privileges to Turda. These were confirmed later by Gabriel Bethlen. In the battle of Turda, Ahmed Pasha defeated George II Rákóczi in 1659.

In 1711 the Grand Principality of Translyvania was formed which became in 1804 part of the Austrian Empire. In 1867, by the Austro-Hungarian Compromise, the city became again part of Hungary. After the First World War following the proclamation of the Union of Transylvania with Romania, Turda as well became part of Romania by the Treaty of Trianon.[8] In 1944, the Battle of Turda took place here, between German and Hungarian forces on one side and Soviet and Romanian forces on the other. It was the largest battle fought in Transylvania during World War II.

From the late 1950s, Turda became a rather important industrial centre, housing factories for chemical, electrotechnical ceramics, cement, glass and steel cables. The nearby Câmpia Turzii town hosted a siderurgy (steel) plant. The city centre of Turda saw redevelopment in the late 1980s, including a House of Culture that hasn't been finished up to this date. Many houses in the historic center were demolished to create space for apartment buildings. The town's role of an industrial powerhouse has diminished from the 1990s onwards, but tourist attractions have kept the city in a good state up to today.
