After Béla's death in 1063, Ladislaus and his elder brother, Géza, acknowledged their cousin Solomon as the lawful king in exchange for receiving their father's former duchy, which included one-third of the kingdom.

[28] A legend preserved in the Illuminated Chronicle mentions that before the battle, Ladislaus "saw in broad daylight a vision from heaven" of an angel placing a crown on Géza's head.

[30][31] Another legendary episode also predicted the dukes' triumph over the king: an "ermine of purest white" jumped from a thorny bush to Ladislaus's lance and then onto his chest.

[28][33] Solomon was defeated,[29] but instead of surrendering to his cousins, he fled to the western borders of the kingdom to seek assistance from his brother-in-law Henry IV of Germany.

[19][43] The majority of these laws were draconian measures to defend private property, showing that Ladislaus primarily focused on internal consolidation and security during the first years of his reign.

[44] His other laws regulated legal proceedings and economic matters, including the issuing of judicial summons and the royal monopoly on salt trade.

[48][49] In 1078 or 1079, Ladislaus married Adelaide, a daughter of Rudolf of Rheinfelden, whom the German princes had elected to take the place of Henry IV as king.

[45][55] Historian László Kontler says that the canonization ceremony, held in August 1083, was also a political act, demonstrating Ladislaus's "commitment to preserving and strengthening" the Christian state.

[56] Ladislaus even dedicated a newly established Benedictine monastery – Szentjobb Abbey – to Stephen's right arm, known as the "Holy Dexter", which was miraculously found intact.

Therefore when they tried in vain to raise the body, a certain recluse at the church of the Holy Savior in Bökénysomlyó, by the name of Karitas, whose famous life at the time was held in esteem, confided to the king by a revelation made to her from heaven that they exerted themselves in vain; it would be impossible to transfer the relics of the holy king until unconditional pardon was offered to Solomon, setting him free from the confinement of prison.

And thus, bringing him forth from the prison, and repeating the three-day fast, when the third day arrived for the transferal of the holy remains, the stone lying over the grave was lifted up with such ease as if it had been of no weight before.After his release, Solomon made a final effort to regain his crown.

[66][65] Thomas the Archdeacon's chronicle describes how Ladislaus "occupied the entire land from the River Drava to the mountains called the Iron Alps without encountering opposition".

[63][76][77] Historian Ferenc Makk writes that the latter title referred to Moesia, implying that Ladislaus had taken the regions between the Great Morava and Drina rivers from the Byzantine Empire.

[80][81][82] In retaliation, the chronicle continues, Ladislaus invaded the neighboring Rus' principalities, forcing the "Ruthenians" to ask "for mercy" and to promise "that they would be faithful to him in all things".

[84] Bernold of St Blasien writes that Duke Welf of Bavaria prevented a conference that Emperor Henry IV "had arranged with the king of the Hungarians" in December 1092.

[81][86] Pope Urban II also mentioned that the Hungarians "left the shepherds of their salvation", implying that Ladislaus had changed sides and acknowledged the legitimacy of Antipope Clement III.

[91] According to a scholarly theory, the sees of the dioceses of Kalocsa and Bihar were moved to Bács (now Bač, Serbia) and Nagyvárad (present-day Oradea, Romania), respectively, during Ladislaus's reign.

[79] The Illuminated Chronicle states that "messengers from France and from Spain, from England and Britain, and especially from Willermus, the brother of the King of the Franks" visited Ladislaus in Bodrog (near present-day Bački Monoštor in Serbia) on Easter 1095, asking him to lead their crusade to the Holy Land.

[98] The whole story was invented, probably during the reign of King Béla III of Hungary (who was actually planning to lead a crusade to the Holy Land in the 1190s), according to historian Gábor Klaniczay.

[102] On the other hand, Ladislaus's late 12th-century "Legend" provides that his attendants buried him in Székesfehérvár, but the cart carrying his body "set out to Várad on its own, unassisted by any draft animal".

[55] His conquest marked the beginning of a period of Hungarian expansion, which ensured that Hungary developed into a leading Central European power during the following centuries.

[111] Hungary had never had as great as king, so they reputeAnd the land thereafter never bore that much and splendid fruit.Gábor Klaniczay emphasizes that Ladislaus "seemed expressly designed to personify the knight-king ideal" of his age.

[114][115] In the battle, the united armies of Solomon, Géza and Ladislaus routed a band of Pechenegs or Oghuz Turks who were plundering the eastern parts of the kingdom.

[117][118] Archaeologist Gyula László says that murals depicting this legend in medieval churches preserved the elements of pagan myths, including a "struggle between forces of light and darkness".

The saintly Duke Ladislaus thought that it was the daughter of the Bishop of Warad, and although he was seriously wounded, he swiftly pursued him on his horse, which he called by the name of Zug.

But the girl was not the bishop's daughter.During the reign of Stephen II of Hungary, Ladislaus's shrine in the cathedral of Várad became a preferred venue for trials by ordeal.

He was canonized in 1192 at the request of King Béla III of Hungary, and his body was exhumed to prepare relics from his skull and other skeletal remains as was the custom in that medieval times.

[131] According to historian György Szabados, Gyula László proved already in 1965 that the face of the Saint Ladislaus' Herma depicts King Béla III.

The first appearance of R-Z2125 in the Carpathian Basin was detected in 5th-century European Huns, and 7th–8th-century Avars, but it also arrived with the conquering Hungarians, in the 9th–10th century including Árpád and his family.

[135] The genomic analyses of the Hungarian royal Árpád family members are in line with the reported conquering Hungarian-Hun origin of the dynasty in harmony with their Y-chromosomal phylogenetic connections.
