Its capital was Claudiopolis (modern Bolu), and its governor held the modest rank of praeses.
History
The province was established under Theodosius I and named after his younger son Honorius. It formed part of the Diocese of Pontus, bordering with Bithynia in the west, Galatia Prima in the south and Paphlagonia in the east.
In the administrative reforms of Emperor Justinian I, the province was united with that of Paphlagonia and formed a new province of Paphlagonia, under a governor styled praetor Iustinianus.
As found in the Notitia Dignitatum. Provincial administration reformed and dioceses established by Diocletian, c. 293. Permanent praetorian prefectures established after the death of Constantine I. Empire permanently partitioned after 395. Exarchates of Ravenna and Africa established after 584. After massive territorial losses in the 7th century, the remaining provinces were superseded by the theme system in c. 640–660, although in Asia Minor and parts of Greece they survived under the themes until the early 9th century.
