What is "romagna"

Romagna ( Romagnol: Rumâgna) is an Italian historical region that approximately corresponds to the south-eastern portion of present-day Emilia-Romagna. Traditionally, it is limited by the Apennines to the south-west, the Adriatic to the east, and the rivers Reno and Sillaro to the north and west. The region's major cities include Cesena, Faenza, Forlì, Imola, Ravenna, Rimini and City of San Marino ( San Marino is a landlocked state inside the Romagna historical region). The region has been recently formally expanded with the transfer of seven comuni ( Casteldelci, Maiolo, Novafeltria, Pennabilli, San Leo, Sant'Agata Feltria, Talamello) from the Marche region, which are a small number of comuni where Romagnolo dialect is spoken.
