The Scythians (/ˈsɪθiən/ or /ˈsɪðiən/) or Scyths (/ˈsɪθs/), also known as the Pontic Scythians, were an ancient Eastern Iranic equestrian nomadic people who migrated during the 9th to 8th centuries BC from Central Asia to the Pontic Steppe in modern-day Ukraine and Southern Russia, where they remained until the 3rd century BC.
Skilled in mounted warfare, the Scythians displaced the Agathyrsi and the Cimmerians as the dominant power on the western Eurasian Steppe in the 8th century BC. In the 7th century BC, the Scythians crossed the Caucasus Mountains and often raided West Asia along with the Cimmerians.
