Böszörmény, also Izmaelita or Hysmaelita ("Ishmaelites") or Szerecsen ("Saracens"), is a name for the Muslims who lived in the Kingdom of Hungary in the 10–13th centuries. Some of the Böszörmény probably joined the federation of the seven Magyar tribes during the 9th century, and later smaller groups of Muslims arrived in the Carpathian Basin. They were engaged in trading but some of them were employed as mercenaries by the kings of Hungary. Their rights were gradually restricted from the 11th century on, and they were coerced to accept baptism following the establishment of the Christian Kingdom of Hungary. They "disappeared" (probably became Christian and/or converted later to Alevism Bektashism in Hungary ) by the end of the 13th century.
