Bosnia and Herzegovina in the Middle Ages in the context of "Ottoman conquest of Bosnia and Herzegovina"

The House of Pavlović, also Radinović or Radenović, or Radinović-Pavlović, was Bosnian noble family who got their name after Radin Jablanić. Radin's father, Jablan, was a founder of Jablanić house, an earlier branch of this medieval Bosnian clan. Jablan's estate was in Jablan village (also Jablanovo, near Lukavica). Later, family extended their feudal possessions from the Middle and Upper Drina river in the eastern parts of medieval Bosnia, known as Pavlovića zemlja, to south-southeastern regions of the Bosnian realm in Hum and Konavle at the Adriatic coast.The family official residence and seat was at Borač and later Pavlovac, above the Prača river canyon, between present-day Prača, Rogatica and Goražde in Bosnia and Herzegovina.

Ras (Serbian Cyrillic: Рас; Latin: Arsa), known in modern Serbian historiography as Stari Ras (Serbian Cyrillic: Стари Рас, "Old Ras"), is a medieval fortress and area located in the vicinity of former market-place of Staro Trgovište, some 10–11 kilometers (6.2–6.8 mi) west of modern-day city of Novi Pazar in Serbia.

Old Ras was initially part of the First Bulgarian Empire (until the 10th century), then Byzantine Empire (mid-10th until mid-12th century), in the end becoming one of the first and main capitals of the Grand Principality and Kingdom of Serbia (from mid-12th until early 14th century). Located in today's region of Raška, its favorable position in the area known as Old Serbia, along the Raška gorge at Pešter plateau, on the crossroads and trading routes between neighbouring regions of Zeta and Bosnia in the west and Kosovo in the south, added to its importance as a city.

The Bosnian Church (Serbo-Croatian: Crkva bosanska, Црква босанска) was an autonomous Christian church in medieval Bosnia and Herzegovina.

Historians traditionally connected the church with the Bogomils, although this has been challenged and is now rejected by the majority of scholars. Adherents of the church called themselves simply Krstjani ("Christians") or Dobri Bošnjani ("Good Bosnians"). The church's organization and beliefs are poorly understood, because few if any records were left by church members and the church is mostly known from the writings of outside sources — primarily Catholic ones.

Stjepan Vukčić Kosača (1404–1466) was a powerful Bosnian nobleman who was politically active from 1435 to 1466; the last three decades of Bosnian medieval history. During this period, three kings acceded to the Bosnian throne: Tvrtko II, Thomas (Tomaš), Stephen Tomašević (Stjepan Tomašević) and anti-king Radivoj—the older brother of King Thomas—before the country was conquered by the Ottomans.

Stjepan, a son of the Knez of Drina, Vukac Hranić, and Katarina, whose ancestry is unknown, was probably born in 1404. Stjepan's father held hereditary lands in the Upper Drina region. Stjepan was a member of the Kosača noble family and became its chieftain in 1435 when he succeeded his uncle, Duke Sandalj, as Duke of Humska zemlja and the Grand Duke of Bosnia. Stjepan influenced the development of the late Bosnian medieval state more than any other person of his era.

The Pavlovac Castle (Serbian Cyrillic: Павловац) was a noble court and one of the largest and most important fortified towns of medieval Bosnia, situated on top of rugged slopes high above the Prača river canyon, near modern days Prača village, in Bosnia and Herzegovina. The fortified castle was a seat of the medieval Bosnian noble family Radinović-Pavlović.
