Hrvoje Vukčić Hrvatinić was a medieval Bosnian nobleman and magnate, Grand Duke of Bosnia, Knez of Donji Kraji, and Duke of Split. He was the most prominent member of the Hrvatinić noble family, and one of the major feudal lords in Kingdom of Bosnia. He was Grand Duke of Bosnia under three Bosnian kings: King Tvrtko I, King Stephen Dabiša and King Stephen Ostoja. In 1403 Ladislaus of Naples named him his deputy for Dalmatia, and bestowed him with a title Duke of Split, later Herzog of Split. He played a crucial role in the dynastic struggles between the Anjou and Luxembourg claimants to the Hungarian-Croatian throne at the end of the 14th century, as well as in the emergence of the Bosnian Kingdom as a regional power during the same period.

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, followed by raids and migrations carried out by Slavic peoples in the 6th and 7th centuries. The first mention of a distinct Bosnian region comes from the 10th-century Byzantine text De Administrando Imperio. By the late 9th and early 10th century, Latin priests had Christianized much of Bosnia, with some areas remaining unconverted. In the High Middle Ages, Bosnia experienced economic stability and peace under the Ban Kulin who ruled over Banate of Bosnia from 1180 to 1204 and strengthened its ties with the Republic of Ragusa and with Venice. The Kingdom of Bosnia emerged in the Late Middle Ages (1377). The kingdom faced internal and external conflicts, eventually falling under Ottoman rule in the late 15th and early 16th centuries.
