The village Szabolcs lies in the county Szabolcs-Szatmár-Bereg in the north-east of Hungary.
It got its name from the Hungarian leader Szabolcs who founded it and settled there in the 9th/10th century. According to Anonymus in the Gesta Hungarorum:
Either the leader, or the place, which once being the residence of the leader was the center of the region, gave the name to the historical county Szabolcs (which was united later with parts of other counties to Szabolcs-Szatmár-Bereg.
translation to English by Wikipedia user "Szabi" from Hungarian "megtekintett egy helyet a Tisza mellett, s midà Ân látta, milyen is az, kiokoskodta, hogy erà Âsségénél fogva várépÃÂtésre való. ÃÂsszegyà ±jtve ott a köznépet, nagy árkot ásatott, és igen erà Âs várat épÃÂttetett földbà Âl. Ezt most Szabolcs várának hÃÂvják.", which is a translation from the Latin text in Gesta Hungarorum. This is not a direct translation from Latin, but a translation-from-a-translation, therefore please, take it with a pinch of salt.
