exarchate
Byzantine administrative term, designating a territorial and and administrative unit. It was formed in late 6th C. in Carthago and Ravenna, both regions of high political and military importance. The exarch (the govrnor of an exarchate) accordingly combined both political and military power. The exarchate of Carthago is attested until the late 7th C., while that of Ravenna until the mid-8th C.

patrikios
(from lat. patricius) Higher title of honour, placed, according to the "Tactika" of the 9th and the 10th centuries, between anthypatos and protospatharios. It was given to the most important governors and generals. Gradually, however, it fell into disuse and from the 12th century did not exist any more.

province
An administrative unit in the Roman and Byzantine Empire. Established in the Roman Empire it is radically reformed by Diocletian, who abolishes the distinction between imperial and senatorial provinces and increases their number by dividing large provinces into smaller ones. Moreover, Diocletian divided the State into 12 dioceses, which included groups of provinces. Administrative reformations in the Byzantine era further increased the number of provinces while reducing their size. Provinces survived until the emrgence of the administrative system of the themes, around 7th c. However the term appears on commerciarii seals until the 9th c., and in written sources of the 11th-12th c. as a synonym of the theme.
