Iazyges

The Iazyges (Jazyges is an orthographic variant) were an ancient nomadic tribe. Known also as Jaxamatae, Ixibatai, Iazygite, Jászok and Ászi, they were a branch of the Sarmatian people who, c. 200 BC, swept westward from central Asia onto the steppes of what is now Ukraine. Little is known about their language, but it was one of the Iranian languages.
