# Trei Scaune County

Trei Scaune County is one of the historical counties of the Kingdom of Romania, in the historical region of Transylvania. The county seat was Sfântu Gheorghe.

## Geography

The county covered 3,337 km$^2$ (1,288 sq mi) and was located in the central part of Greater Romania, in the southeast of Transylvania. Its territory comprised a large part of the current territory of Covasna County.
It was bordered west by Brașov County, to the north by the counties of Odorhei, Ciuc, and Bacău, to the east by Putna County, and to the south by Buzău County. The county was disbanded with the administrative reform of 6 September 1950.

## History

Prior to World War I, the territory of the county belonged to Austria-Hungary and mostly was identical with the Háromszék County of the Kingdom of Hungary. The territory of Trei Scaune County was transferred to Romania from Hungary as successor state to Austria-Hungary in 1920 under the Treaty of Trianon. After the administrative unification law in 1925, the name of the county remained as it was, but the territory was reorganized.
In 1938, King Carol II promulgated a new Constitution, and subsequently he had the administrative division of the Romanian territory changed. 10 ținuturi (approximate translation: "lands") were created (by merging the counties) to be ruled by rezidenți regali (approximate translation: "Royal Residents") — appointed directly by the King — instead of the prefects. Trei Scaune County became part of Ținutul Argeș.
In 1940, nearly all of the county was transferred back to Hungary with the rest of Northern Transylvania under the Second Vienna Award; the small remainder was added to Putna County and to Brașov County. In September–October 1944, Romanian forces with Soviet assistance recaptured the ceded territory and reintegrated it into Romania, re-establishing the county. Romanian jurisdiction over the entire county per the Treaty of Trianon was reaffirmed in the Paris Peace Treaties, 1947. The county was disestablished by the communist government of Romania in 1950 and its territory became part of the Stalin Region. Trei Scaune County was not re-established in 1968 when Romania restored the county administrative system.
