During the last years of his life, he wandered throughout the country with his Cuman allies, but he was unable to control the most powerful lords and bishops any more.

[5][8] Ladislaus initially was kept in the Turóc Castle by Andrew Hont-Pázmány, but two months later, he was sent to the court of Boleslaw the Chaste, Duke of Cracow, who was Béla IV's son-in-law.

[5][12] Béla IV died on 3 May 1270, and Ladislaus's father was crowned king two weeks later;[12][13] the new monarch, however, could not stabilize his rule.

[12][15] The newly appointed ban of Slavonia, Joachim Gutkeled, also turned against Stephen V and kidnapped Ladislaus in the summer of 1272.

[12] Historian Pál Engel suggests that Joachim Gutkeled planned to force Stephen V to divide Hungary with Ladislaus.

[17][18] Stephen V's master of the treasury, Egidius Monoszló, laid siege to her palace in Székesfehérvár, but Gutkeled's supporters routed him.

[19][20] In November of that year, Henry Kőszegi returned from Bohemia and assassinated Ladislaus's cousin, Béla of Macsó.

[21][22] Duke Béla's extensive domains, which were located along the southern borders, were divided among Henry Kőszegi and his supporters.

[17][21] In retaliation for Hungarian incursions into Austria and Moravia, Austrian and Moravian troops invaded the borderlands of Hungary in April 1273.

[23] Joachim Gutkeled recaptured the two forts two months later, but Ottokar II of Bohemia invaded Hungary and seized many fortresses, including Győr and Sopron in the autumn.

[26][27] Although Peter Csák liberated the king and his mother, Gutkeled and Kőszegi captured Ladislaus's younger brother, Andrew, and took him to Slavonia.

[21][26][27] They demanded Slavonia in Duke Andrew's name, but Peter Csák defeated their united forces near Polgárdi at the end of September.

[31] Sopron soon accepted Ladislaus's suzerainty and Ottokar II promised to renounce of all towns he occupied in western Hungary.

[31] However, new armed conflicts began in Hungary during 1277: the Transylvanian Saxons captured and destroyed Gyulafehérvár (now Alba Iulia in Romania), the see of the bishop of Transylvania, and the Babonići rose up in rebellion in Slavonia.

[33] He met Rudolf I of Germany in Hainburg an der Donau on 11 November to confirm their alliance against Ottokar II of Bohemia.

[33] After the royal army captured the rebellious Nicholas Geregye's fortress at Adorján (now Adrian in Romania), Ladislaus held a "general assembly" for seven counties along the River Tisza in early summer of 1278.

[36] Pope Nicholas III sent Philip, bishop of Fermo, to Hungary to help Ladislaus restore royal power on 22 September 1278.

[37] An assembly held at Tétény passed laws which, in accordance with the legate's demand, prescribed that the Cumans should leave their tents and live "in houses attached to the ground".

[44] According to the Austrian Rhymed Chronicle, Bishop Philip of Fermo left Hungary around the same time, stating that he would never come back, "not for the sake of the Holy Father".

[39] At the end of 1282, Ladislaus laid siege to Borostyánkő (now Bernstein im Burgenland in Austria), which was held by the Kőszegis.

[39] In fact, Ladislaus employed Mongol prisoners of war, known as nyögérs, when he subjugated a rebellion in the Szepesség in September 1285.

[55] He abducted his sister, Elizabeth, prioress of the Dominican Monastery of the Blessed Virgin on Rabbits' Island, and gave her in marriage to a Czech aristocrat, Záviš of Falkenstein.

[56] According to Archbishop Lodomer, Ladislaus even stated, "If I had 15 or more sisters in as many cloistered communities as you like, I would snatch them from there to marry them off licitly or illicitly; in order to procure through them a kin-group who will support me by all their power in the fulfillment of my will".

[39][58] For example, Ivan Kőszegi and his brothers waged wars against Albert I, Duke of Austria, but Ladislaus did not intervene, although the Austrians captured at least 30 fortresses along the western borders.

[60] Upon Pope Nicholas IV's orders, an inquiry was carried out to find out "whether the king died as a Catholic Christian".

[67] The results of the investigation are unknown, but the Chronicon Budense writes that Ladislaus was buried in the cathedral of Csanád (now Cenad in Romania).
