The settlement formed part of the Székely Land region of the historical Transylvania province. Until 1918, the village belonged to the Háromszék County of the Kingdom of Hungary. In the immediate aftermath of World War I, following the declaration of the Union of Transylvania with Romania, the area passed under Romanian administration during the Hungarian–Romanian War of 1918–1919. By the terms of the Treaty of Trianon of 1920, it became part of the Kingdom of Romania. In 1925, the commune fell in Plasa Sfântu Gheorghe of Trei Scaune County. In August 1940, under the auspices of Nazi Germany, which imposed the Second Vienna Award, Hungary retook the territory of Northern Transylvania (which included Ghidfalău) from Romania. Towards the end of World War II, however, the commune was taken back from Hungarian and German troops by Romanian and Soviet forces in September–October 1944. In 1950, after Communist Romania was established, Brateș became part of the Sfântu Gheorghe Raion of Stalin Region. From 1952 and 1960, it was part of the Magyar Autonomous Region, and between 1960 and 1968 it reverted to Brașov Region. In 1968, when Romania was reorganized based on counties rather than regions, the commune became part of Covasna County.
