The village formed part of the Székely Land region of the historical Transylvania province.

In 1925, the commune fell within 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 Micfalău) 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 1944.

In 1950, after Communist Romania was established, Micfalău became part of the Târgu Secuiesc Raion of Stalin Region.
