LÁSZLÓ (in Poland [1046/50][486]-Nitra 20 Jun 1095, bur Somogyvár, transferred 1192 to Nagyvárad Cathedral[487]). The Gesta Hungarorum names "Geichæ et Ladislai" as sons of "fratris sui Belæ" when recording that King András obtained their agreement to the future succession of his son Salomon[488]. The Kronika Wegiersko-Polska names "Geyzam et Ladislaum" as the two older sons of "Bela" and his wife "rex Polonie filiam", adding that they were both born in Poland[489]. "Magnus qui et Geysa supremus Hungarorium Dux postea…rex consecratus, Belæ regis filius" founded the monastery of St Benedict, Gron, in the presence of "Ladislao Duce germano meo…Iula Comite Palatino", by charter dated 1075[490]. He succeeded his brother in 1077 as LÁSZLÓ I King of Hungary. He extended the borders of Transylvania eastwards and settled a privileged class of border guards there as protection against incursions by the Kumans[491]. The Gesta Hungarorum records that King László inflicted a crushing defeat on the Kumans at "Kyrioleis [Chirasles]" mountain in Transylvania[492]. The Chronicon Posoniense records that "Ladizlaus rex et Salomon frater eius" made peace in 1081 and that "crux domini" was struck by lightning in the same year[493]. "Ladislaus…Hungarorum Rex Belæ regis filius" confirmed the foundation of the church of Besprem, "cum Sug comite de Bukon (huius filius fuerit Bodus Salamonis in carcere socius)", by charter dated 1082[494]. After the succession of his sister Ilona as Queen of Croatia, he intervened to protect her interests against the considerable opposition she faced from the Croatian nobility, and occupied much of Croatia including part of Dalmatia. He was obliged to withdraw from Dalmatia to defend Hungary against an attack by Kumans, but retained Pannonian Croatia. "Ladislaus…Hungarorum Rex" confirmed the privileges of the church of St Adrian "in insula Szalad" by charter dated 20 Dec 1091[495]. "Ladislauo…Rex" founded the church of St Egidius, Sumich by charter dated 1091 witnessed by "Dux Lambertus frater eius, Dux David consobrinus, Gerazclauus filius regis Rutenorum gener ipsius…Comes Palatinus Petrus et comes Acha…"[496]. In 1091, he created a special Croatian banovina between the Drava River and Gvozd Mountains, ruled by his nephew Álmos, but this was recaptured by Peter King of Cro atia in 1095[497]. A charter dated 17 Apr 1093 records that "regem Ladislaum" reformed five churches, witnessed by "…comitibus Spiguen Grab, Gwth…"[498]. The Historia Salonitanorum of Thomas Archdeacon of Split records that "rex Suinimirus" died without leaving an heir from his posterity, and that "quidam ex magnatibus Sclavonie" went "in Hungariam…ad regem Vladisclavum" requesting him to intervene in Croatia to put an end to the chaos which followed the king's death[499]. He was killed during a raid by the Kumans[500]. King László had designated his nephew Álmos as his successor, but Álmos's older brother Kálmán seized the throne in 1095 when King László died[501]. The Chronicon of Mariano Scotti records the death in 1095 of "Ladizlaus rex Pannoniæ"[502]. The Annales Gradicenses record the death in 1095 of "Wladizlaus rex Ungarorum"[503]. The Chronicon Posoniense records the death in 1097 of "Ladislaus rex"[504]. The Chronicon Varadiense records the death "IV Kal Aug" in 1095 of "rex Ladislaus filius secundogenitus regis Belæ dicti Belyn" and his burial "in suo monasterio Varadini"[505]. The Gesta Hungarorum records that King László was buried at "Warod [Oradea]"[506]. László was later canonised by the Catholic church, his feast-day is 27 Jun[507]. m ([1077 or after]) ADELHEID von Rheinfelden, daughter of RUDOLF Graf von Rheinfelden Duke of Swabia [anti-King of Germany] & his second wife Adelaide de Savoie ([1063/65]-3 May 1090, bur St Blasius). "Filia eorum Adilheida regina que nupsit regi Ungariorum" and "progenitoribus Rodolfo…rege et Adelheida…regina matertera Heinrici quarti inperatoris" are named in a donation to Sankt-Blasien by charter dated [1079/10 Oct 1086] which also names "cuius filius [Rodolfo et Adelheida] Bertholfus…dux frater regine nostre…cum fratre suo Ottone"[508]. Her birth date is estimated from the estimated birth date range of her supposed daughter Piroska (although, as noted below, there is doubt concerning Piroska's parentage). The Chronicon of Bernold records that "soror quoque præfati ducis [Berthaldus dux Alemanniæ, filius Roudolfi regis] regina Ungarorum" died in the same month and year as her brother[509]. The name of her husband is not stated in any of the contemporary sources so far identified. However, King László appears to be the most likely possibility: considering Adelheid's estimated birth date, her husband is unlikely to have been King Géza, whose death is recorded in 1077, and King Géza's son Kálmán did not succeeded until 1095, after the recorded date of Adelheid's death as "regina Ungarorum". This supposition is confirmed by the charter dated 1201 under which Imre King of Hungary restored "prædio…Merena", donated by "regina Adulheyth, uxor…bonæ memoriæ regis Ladislai", to "ecclesiæ beati Michaëlis de Vesprimio"[510]. Kerbl suggests that the marriage was arranged by King László as part of his policy of seeking Papal support, his future father-in-law being the candidate for the German throne supported by the Pope[511]. The necrology of Seeon records the death "V Non May" of "Adelheit regina Ungariorum"[512]. King László I & his wife had two daughters
