Boii

The Boii (Latin plural, singular Boius; Greek Βόϊοι) were one of the most prominent ancient Celtic tribes of the later Iron Age, attested at various times in Cisalpine Gaul (northern Italy), Pannonia (Hungary and its western neighbours), in and around Bohemia, and Transalpine Gaul. In addition the archaeological evidence indicates that in the 2nd century BC Celts expanded from Bohemia through the Kłodzko valley into Silesia, now part of Poland.
