Bosnia and Herzegovina in the Middle Ages

The history of Bosnia and Herzegovina in the Middle Ages refers to the time period between the Roman era and the 15th-century Ottoman conquest. The Early Middle Ages in the Western Balkans saw the region reconquered from barbarians (Ostrogoths) by the Byzantine Emperor Justinian I (r. 527–565), followed by raids and migrations carried out by Slavic peoples in the 6th and 7th centuries.
