Input: Question: What modern country is Transylvania a part of? Passage:The component villages were historically part of the Szekely Land area of Transylvania and belonged to Csikszek district until the administrative reform of Transylvania in 1876, when they fell within Csik County in the Kingdom of Hungary. After the Treaty of Trianon of 1920, they became part of Romania and fell within Ciuc County during the interwar period. In 1940, the second Vienna Award granted the Northern Transylvania to Hungary and they were held by Hungary until 1944. After Soviet occupation, the Romanian administration returned and the town became officially part of Romania in 1947. Between 1952 and 1960, the commune fell within the Magyar Autonomous Region, between 1960 and 1968 the Mures-Magyar Autonomous Region. In 1968, the province was abolished, and since then, the commune has been part of Harghita County.
