Atid (Hungarian: Etéd, pronounced [ˈɛteːd]) is a commune in Harghita County, Romania. It lies in the Székely Land, an ethno-cultural region in eastern Transylvania.
The commune is composed of five villages:
From ancient times the area was populated by Dacians. After the Roman conquest of Dacia, the Romans imposed their control in the area by constructing a fort known as Praetoria Augusta in Inlăceni village. The fort was discovered in 1858.
The villages were historically part of the Székely Land region of Transylvania province. They belonged to Udvarhely district until the administrative reform of Transylvania in 1876, when they fell within Udvarhely County in the Kingdom of Hungary. After the Treaty of Trianon of 1920, they became part of Romania and fell within Odorhei County during the interwar period. In 1940, the second Vienna Award granted Northern Transylvania to Hungary, which held it until 1944. After Soviet occupation, the Romanian administration returned, and the commune became officially part of Romania in 1947. Between 1952 and 1960, the commune fell within the Magyar Autonomous Region, between 1960 and 1968 the Mureş-Magyar Autonomous Region. In 1968, the province was abolished, and since then, the commune has been part of Harghita County.
