 The Avars in the region known as "solitudo avarorum"currently called the Alföldvanished in an arc of three generations.They slowly merged with the Slavs to create a bilingual Turkic-Slavic-speaking people who were subjected to Frankish domination; the invading Magyars found this composite people in the late 9th century.The "De Administrando Imperio", written around 950, clearly states the presence of an Avar population in the region of modern-day Croatia.
