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.
The House of Hrvatinić was a Bosnian medieval noble family that emerged in Donji Kraji county, located in today's territory of western Bosnia and Herzegovina. Principally they were vassals to Kotromanić dynasty of the Banate of Bosnia and Kingdom of Bosnia, occasionally also to the Kingdom of Hungary, changing loyalties between Hungarian kings Ladislaus of Naples and Sigismund of Luxembourg, and finally the Ottoman Empire (1472–1476). They rose to prominence in the second half of the 14th century, and attained its peak under magnate Hrvoje Vukčić Hrvatinić (1350–1416), who also held large swaths of Dalmatia and obtained title of Grand Duke of Bosnia in 1380.

Usora was important zemlja of the medieval Bosnian state, first banate and later kingdom, although it also had some periods outside its jurisdiction and royal authority, when it was connected with neighboring banates of Slavonia, or Mačva at times.

It took its name from the river Usora.

The Banate of Bosnia, or Bosnian Banate, was a medieval state based in what is today Bosnia and Herzegovina. Although Hungarian kings viewed Bosnia as part of Hungarian Crown Lands, the Banate of Bosnia was a de facto independent state for most of its existence. It was founded in the mid-12th century and existed until 1377 with interruptions under the Šubić family between 1299 and 1324. In 1377, it was elevated to a kingdom. The greater part of its history was marked by a religiopolitical controversy revolving around the native Christian Bosnian Church condemned as heretical by the dominant Chalcedonian Christian churches, namely the Roman Catholic and Eastern Orthodox, with the Catholic church being particularly antagonistic and persecuting its members through the Hungarians.
The Kingdom of Bosnia, or Bosnian Kingdom, was a medieval kingdom that lasted for nearly a century, from 1377 to 1463, and evolved out of the Banate of Bosnia, which itself lasted since at least 1154.
