noun. The office, dignity, or administration of an exarch, or the territory ruled by an exarch; specifically, the Byzantine dominion in Italy after its reconquest from the Ostrogoths by Narses in the middle of the sixth century, called from its capital the exarchate of Ravenna. At first it embraced all Italy, but parts of it were rapidly lost, until only the region around Ravenna (the Romagna) was retained by the exarch. This was conquered by the Lombards in 751, and taken from them by Pepin the Short, king of the Franks, in 755, and given to the pope, who thus became a temporal sovereign.
