Pontic Steppe in the context of "Cimmerians"

The early Slavs were an Indo-European peoples and speakers of the Indo-European dialectswho lived during the Migration Period and the Early Middle Ages (approximately from the 5th to the 10th centuries AD) in Central, Eastern and Southeast Europe and established the foundations for the Slavic nations through the Slavic states of the Early and High Middle Ages. The Slavs' original homeland is still a matter of debate due to a lack of historical records; however, scholars generally place it in Eastern Europe, with Polesia being the most commonly accepted location.

It is generally agreed that ancient Roman writers referred to the ancestors of Slavs as Venedi. The proto-Slavic term Slav shares roots with Slavic terms for speech, word, and perhaps was used by early Slavic people themselves to denote other people, who spoke languages similar to theirs. The first written use of the name "Slavs" dates to the 6th century, when the Slavic tribes inhabited a large portion of Central and Eastern Europe. By then, the nomadic Iranian-speaking peoples living in the European Pontic Steppe (the Scythians, Sarmatians, Alans, etc.) had been absorbed by the region's Slavic-speaking population. Over the next two centuries, the Slavs expanded westwards (to the Elbe river and in the Alps), and southwards (into the Balkans, absorbing Illyrian and Thracian peoples in the process), and also moved eastwards (in the direction of the Volga River). Between the sixth and seventh centuries, large parts of Europe came to be controlled or occupied by Slavs, a process less understood and documented than that of the Germanic ethnogenesis in the west. Yet the effects of Slavicization were far more profound.

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.

The Alans (Latin: Alani) were an ancient and medieval Iranic nomadic pastoral people who migrated to what is today North Caucasus; some continued on to Europe and later North Africa. They are generally regarded as part of the Sarmatians, and possibly related to the Massagetae. Modern historians have connected the Alans with the Central Asian Yancai of Chinese sources and with the Aorsi of Roman sources. Having migrated westwards and becoming dominant among the Sarmatians on the Pontic–Caspian steppe, the Alans are mentioned by Roman sources in the 1st century CE. At that time they had settled the region north of the Black Sea and frequently raided the Parthian Empire and the South Caucasus provinces of the Roman Empire. From 215 to 250 CE the Goths broke their power on the Pontic Steppe, thereby assimilating a sizeable portion of the associated Alans.

Upon the Hunnic defeat of the Goths on the Pontic Steppe around 375 CE, many of the Alans migrated westwards along with various Germanic tribes. They crossed the Rhine in 406 along with the Vandals and Suebi, settling in Orléans and Valence. Around 409 they joined the Vandals and Suebi in crossing the Pyrenees into the Iberian Peninsula, settling in Lusitania and Hispania Carthaginensis. The Iberian Alans, soundly defeated by the Visigoths in 418, subsequently surrendered their authority to the Hasdingi Vandals. In 428 CE, the Vandals and Alans crossed the Strait of Gibraltar into North Africa, where they founded a kingdom which lasted until its conquest by forces of the Byzantine Emperor Justinian I in 534.

Marija Gimbutas (Lithuanian: Marija Birutė Alseikaitė-Gimbutienė, pronounced ['ɡʲɪmbutas]; January 23, 1921 – February 2, 1994) was a Lithuanian archaeologist and anthropologist known for her research into the Neolithic and Bronze Age cultures of "Old Europe" and for her Kurgan hypothesis, which located the Proto-Indo-European homeland in the Pontic Steppe.
