 The Jasz people were a nomadic Sarmatian (or Scythian) tribe which settled in the medieval Kingdom of Hungary during the 13th century and are generally thought to be of Ossetian origin originally speaking a dialect of the Ossetic language.The dialect is extinct and members of the Jász usually speak Hungarian.Their name is almost certainly related to that of the Iazyges, one of the Sarmatian tribes which, along with the Roxolani, reached the borders of Dacia during the late 1st century BC (the city of Iași is named for them).
