The rpds or Arpads (Hungarian: rpd-hz, Croatian: Arpadovii, Serbian: , Slovak: Arpdovci) were the ruling dynasty of the Principality of Hungary in the 9th and 10th centuries and of the Kingdom of Hungary from 1000 to 1301. The dynasty was named after the Hungarian Grand Prince rpd who was the head of the Hungarian tribal federation during the conquest of the Carpathian Basin, c. 895. It is also referred to as the Turul dynasty, and this was the official name until the 18th century.Both the first Grand Prince of the Hungarians (lmos) and the first king of Hungary (Saint Stephen) were members of the dynasty.

Eight members of the dynasty were canonized or beatified by the Catholic Church; therefore, since the 13th century the dynasty has often been referred to as the "Kindred of the Holy Kings". Two rpds were recognized as Saints by the Eastern Orthodox Church.

The dynasty came to end in 1301 with the death of King Andrew III of Hungary, while the last member of the House of rpd, Andrew's daughter, Blessed Elizabeth of Tss, died in 1336 or 1338. All of the subsequent kings of Hungary (with the exception of King Matthias Corvinus) were cognatic descendants of the rpd dynasty. The House of Cro and the Drummond family of Scotland claim to descend from Gza and George, sons of medieval Hungarian kings: Gza II and Andrew I, respectively.

Andrew III the Venetian (Hungarian: III. Velencei András, Croatian: Andrija III. Mlečanin, Slovak: Ondrej III.; c. 1265 – 14 January 1301) was King of Hungary and Croatia between 1290 and 1301. His father, Stephen the Posthumous, was the posthumous son of Andrew II of Hungary although Stephen's brothers considered him a bastard. Andrew grew up in Venice, and first arrived in Hungary upon the invitation of a rebellious baron, Ivan Kőszegi, in 1278. Kőszegi tried to play Andrew off against Ladislaus IV of Hungary, but the conspiracy collapsed and Andrew returned to Venice.

Being the last male member of the House of Árpád, Andrew was elected king after the death of King Ladislaus IV in 1290. He was the first Hungarian monarch to issue a coronation diploma confirming the privileges of the noblemen and the clergy. At least three pretenders—Albert of Austria, Mary of Hungary, and an adventurer—challenged his claim to the throne. Andrew expelled the adventurer from Hungary and forced Albert of Austria to conclude a peace within a year, but Mary of Hungary and her descendants did not renounce their claim. The Hungarian bishops and Andrew's maternal family from Venice were his principal supporters, but the leading Croatian and Slavonian lords were opposed to his rule.

Hungary was in a state of constant anarchy during Andrew's reign. The Kőszegis, the Csáks, and other powerful families autonomously governed their domains, rising up nearly every year in open rebellion against Andrew. With Andrew's death, the House of Árpád became extinct. A civil war ensued which lasted for more than two decades and ended with the victory of Mary of Hungary's grandson, Charles Robert.
