Brateș is crossed by national road DN13E [ro], which starts in Întorsura Buzăului, in the south of the county, passes through Covasna and Sfântu Gheorghe, and ends in Feldioara, 50 km (31 mi) to the west, in Brașov County.
The settlement formed part of the Székely Land region of the historical Transylvania province.
In August 1940, under the auspices of Nazi Germany, which imposed the Second Vienna Award, Hungary retook the territory of Northern Transylvania (which included Brateș) 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.
