Stephen V of Hungary in the context of "Philip I, Prince of Taranto"

The Duke of Transylvania (Hungarian: erdélyi herceg; Latin: dux Transylvaniae) was a title of nobility four times granted to a son or a brother of the Hungarian monarch. The dukes of the first and second creations, Béla (1226–1235) and Stephen (1257–1258 or 1259, 1260–1270) of the Árpád dynasty were in fact viceroys with significant authority in Transylvania. The duke of the third creation, Louis, did not administer the province. The fourth duke, Stephen of the Anjou dynasty (1350–1351) did not play any significant role in politics.

Mary of Hungary (c. 1257 – 25 March 1323), of the Árpád dynasty, was Queen of Naples and Queen of Albania by marriage to King Charles II. She was a daughter of Stephen V of Hungary and his wife Elizabeth the Cuman. Mary served as regent in Provence in 1290–1294 and in Naples in 1295–96, 1296–98, and 1302, during the absences of her husband.

Charles Martel (Hungarian: Martell Károly, Italian: Carlo Martello; 8 September 1271 – 12 August 1295) of the Capetian dynasty was the eldest son of king Charles II of Naples and Mary of Hungary, the daughter of King Stephen V of Hungary.

The 18-year-old Charles Martel was set up by Pope Nicholas IV and the ecclesiastical party as the titular King of Hungary (1290–1295) as the successor of his maternal uncle, the childless Ladislaus IV of Hungary against whom the Pope had already earlier declared a crusade.

Catherine of Hungary (Hungarian: Katalin, Serbian: Каталина, romanized: Katalina; c. 1256 – after 1314) was a Queen consort of Serbia by her marriage to Stefan Dragutin. Catherine was the second daughter of Stephen V of Hungary and his wife Elizabeth, daughter of Seyhan, chieftain of the Cumans.

Simon of Kéza (Hungarian: Kézai Simon) was the most famous Hungarian chronicler of the 13th century. He was a priest in the royal court of king Ladislaus IV of Hungary.

In 1270–1271, bearing the title "master" (magister), Simon was part of a diplomatic mission led by Sixtus of Esztergom. Andrew of Hungary was also a part of this mission. Sent by King Stephen V of Hungary to congratulate King Charles I of Sicily on the latter's return from the Eighth Crusade, the delegation travelled via Naples to Catona and Messina in December and January, then back with Charles to Rome in February.

Ladislaus IV (Hungarian: IV. (Kun) László, Croatian: Ladislav IV. (Kumanac), Slovak: Ladislav IV. (Kumánsky); 5 August 1262 – 10 July 1290), also known as Ladislaus the Cuman, was King of Hungary and Croatia from 1272 to 1290. His mother, Elizabeth, was the daughter of a chieftain from the pagan Cumans who had settled in Hungary. At the age of seven, he married Elisabeth (or Isabella), a daughter of King Charles I of Sicily. Ladislaus was only 9 when a rebellious lord, Joachim Gutkeled, kidnapped and imprisoned him.

Ladislaus was still a prisoner when his father Stephen V died on 6 August 1272. During his minority, many groupings of barons – primarily the Abas, Csáks, Kőszegis, and Gutkeleds – fought against each other for supreme power. Ladislaus was declared to be of age at an assembly of the prelates, barons, noblemen, and Cumans in 1277. He allied himself with Rudolf I of Germany against Ottokar II of Bohemia. His forces had a preeminent role in Rudolf's victory over Ottokar in the Battle on the Marchfeld on 26 August 1278.
