 During the early 19th century, Hungarian acculturation continued, with the Greeks and Aromanians of Kecskemét speaking Hungarian by 1846.Geographer Johann Georg Kohl described the Cumans themselves as "completely Magyarized" in 1840, though noting that they were set apart by a "warlike spirit".In tandem, revivalists began referring to ancient Cuman customs and ethnic markers, which in some cases are suspect of being invented traditions.
