The place first appears in writing in 1102, under the name Beys, and it appears as a border settlement of the Pechenegs — a steppe people whom the kings of Hungary settled along their frontiers to watch the crossings. The job made sense here. The Danube split into dozens of branches across this island, and whoever knew the fords decided who could get over. There was no stone anywhere on the island and no ground higher than a bank of silt, so nothing was built to last: the early village lived on grain, cattle, fish from the branches and timber from the floodplain forest.Prvý raz sa miesto spomína v písomnostiach v roku 1102 pod menom Beys, a to ako pohraničná osada Pečenehov — stepného národa, ktorý uhorskí králi usadzovali pozdĺž hraníc, aby strážil brody. Tu to dávalo zmysel. Dunaj sa na ostrove delil na desiatky ramien a kto poznal brody, ten rozhodoval, kto sa dostane na druhú stranu. Kameň na ostrove nebol nikde a vyššie miesto než naplavená lavica tiež nie, takže sa tu nestavalo nič na večnosť: raná dedina žila z obilia, dobytka, rýb z ramien a z dreva lužného lesa.
