Béla I the Boxer or the Wisent (, ; – 11 September 1063) was King of Hungary from 1060 until his death. He descended from a younger branch of the Árpád dynasty. Béla's baptismal name was Adalbert. He left Hungary in 1031, together with his brothers, Levente and Andrew, after the execution of their father, Vazul. Béla settled in Poland and married Richeza (or Adelaide), daughter of Polish king Mieszko II Lambert. He returned to his homeland upon the invitation of his brother Andrew, who had in the meantime been crowned King of Hungary. Andrew assigned the administration of the so-called ducatus or "duchy", which encompassed around one-third of the territory of the Kingdom of Hungary, to Béla. The two brothers' relationship became tense when Andrew had his own son, Solomon, crowned king, and forced Béla to publicly confirm Solomon's right to the throne in 1057 or 1058. Béla, assisted by his Polish relatives, rebelled against his brother and dethroned him in 1060. He introduced monetary reform and subdued the last uprising aimed at the restoration of paganism in Hungary. Béla was fatally injured when his throne collapsed while he was sitting on it. Life Childhood (before 1031) Most Hungarian chronicles, including Simon of Kéza's Gesta Hungarorum and the Illuminated Chronicle, record that Béla's father was Ladislas the Bald, a cousin of Stephen, the first King of Hungary. However, many of the same sources add that it "is sometimes claimed" that Béla and his two brothersLevente and Andrewwere in fact the sons of Ladislaus the Bald's brother, Vazul. The chronicles also refer to gossip claiming that the three brothers were their father's illegitimate sons, born to "a girl from the Tátony clan". Modern historians, who accept the latter reports' reliability, unanimously write that the three brothers were the sons of Vazul and his concubine. Béla was born between 1015 and 1020. It is debated whether Béla was a second or a third son. The former view is represented, for example, by the Polish historian Wincenty Swoboda, and the latter by the Hungarian scholars Gyula Kristó and Ferenc Makk. Kristó and Makk write that Béla's name "most probably" derived from the Turkish adjective bujla ("noble"). However, the name may also be connected to the Slavic word for white (bjelij) or to the Biblical name Bela. In exile (1031 – c. 1048) King Stephen's only son who survived infancy, Emeric, died on
