The name formerly applied to a loosely defined district in Central Germany, which, as the home of the Franks, was regarded as the heart of the Holy Roman Empire; the emperors long continued to be crowned within its boundaries; subsequently it was divided into two duchies, East Franconia and Rhenish Franconia; the latter was abolished in 1501 and the former much diminished; from 1806 to 1837 the name had no official existence, but in 1837 the names Upper, Middle, and Lower Franconia were given to the three northern divisions of Bavaria.
