Although officially Andrew is considered to be the last king of the Árpád dynasty, it is not certain, since his lineal descent was doubted. Perhaps it was the reason why his father Stephen gave him the title of Duke of Slavonia in his will that also served as his legal claim for the Hungarian throne later. However, Andrew III also needed a bit of a luck to get to the throne. The unpopular king Ladislaus IV’s (the Cuman’s) younger brother died in 1278, therefore Andrew in Venice was considered the next king. He was crowned in summer 1290 as Andrew III.
He was the first king who had to take an oath to a coronation charter read aloud. According to the major points of that charter, the king swore to be loyal to the Church, to persecute those plundering and devastating the country, to enrich Hungary, and to reconquer her previously occupied territories. In accordance with the charter, Andrew III reconquered from Austria the Western Hungarian cities and castles within a year.
In 1292 Stephen V’s daughter Mary, who laid claim to the throne, together with her husband Charles II of Naples called the Kőszegis to rise up in open rebellion against Andrew. The king could only beat the rising by the end of 1296. In the meantime, he also managed to defeat the uprising led by the voivode of Transylvania.
Meanwhile, he also took some successful measures concerning internal political issues. He issued and put in writing the laws of the parliament of 1298, and also declared the villeins’ right of movement. In order to strengthen his position, Andrew entered into a formal alliance with five influential noblemen in order to support each other.
