Origin The Scythians originated in the region of the Volga-Ural steppes of
Central Asia, possibly around the 9th century BC, as a section of the population of the
Srubnaya culture containing a significant element originating from the Siberian
Andronovo culture. The population of the Srubnaya culture was among the first truly
nomadic pastoralist groups, who themselves emerged in the
Central Asian and
Siberian
steppes during the 9th century BC as a result of the cold and dry climate then prevailing in these regions. During the 9th to 8th centuries BC, a significant movement of the nomadic peoples of the
Eurasian Steppe started when another nomadic Iranic tribe closely related to the Scythians from eastern Central Asia, either the
Massagetae or the
Issedones, migrated westwards, forcing the early Scythians to the west across the
Araxes river. Over the course of the 8th and 7th centuries BC, the Scythians migrated into the Caucasian and Caspian Steppes in several waves, becoming the dominant population of the region, where they assimilated most of the Cimmerians and conquered their territory, with this absorption of the Cimmerians by the Scythians being facilitated by their similar ethnic backgrounds and lifestyles, after which the Scythians settled in the area between the Araxes, the Caucasus and the
Lake Maeotis. The section of the Scythians from whom the Melanchlaeni originated participated in this migration, and had established itself in Ciscaucasia around . From their base in the Caucasian Steppe, during the period of the 8th to 7th centuries BC itself, the Scythians conquered the Pontic and Crimean Steppes to the north of the Black Sea up to the
Danube river, which formed the western boundary of Scythian territory onwards, with this process of Scythian takeover of the Pontic Steppe becoming fully complete by the 7th century BC. Archaeologically, the westwards migration of the Early Scythians from Central Asia into the Caspian Steppe constituted the latest of the two to three waves of expansion of the Srubnaya culture to the west of the Volga. The last and third wave corresponding to the Scythian migration has been dated to the 9th century BC. The expansion of the Scythians into the Pontic Steppe is attested through the westward movement of the Srubnaya-Khvalynsk culture into Ukraine. The Srubnaya-Khvalynsk culture in Ukraine is referred to in scholarship as the "Late Srubnaya" culture.
Migration towards the forest steppe From the Caucasian steppe, the tribe of the Royal Scythians expanded to the south, following the coast of the
Caspian Sea and arrived in the
Ciscaucasian steppes, from where they settled in eastern
Transcaucasia until the early 6th century BC. The Royal Scythians were finally expelled from West Asia in the , after which, beginning in the later 7th and lasting throughout much of the 6th century BC, the majority of the Scythians migrated from Ciscaucasia into the
Pontic Steppe, which became the centre of Scythian power. The retreat of the Royal Scythians from West Asia into the Pontic steppe pushed a Scythian splinter group to the north, into the region of Donets-Kramatorsk, where they formed the Vorskla and Sula-Donets groups of the Scythian culture, of which the Donets group corresponded to the Melanchlaeni, the Sula group to the
Androphagi, and the Vorskla group to the
Budini., with all of these groups remaining independent from the
Scythians proper. Of these groups, the Melanchlaeni and the Androphagi were closely related tribes.
The Persian invasion When the
Persian Achaemenid king
Darius I attacked the Scythians in 513 BC, the Scythian king
Idanthyrsus summoned the kings of the peoples surrounding his kingdom to a meeting to decide how to deal with the Persian invasion. The kings of the
Budini,
Gelonians and
Sarmatians accepted to help the Scythians against the Persian attack, while the kings of the
Agathyrsi,
Androphagi, Melanchlaeni,
Neuri, and
Tauri refused to support the Scythians. During the campaign, the Scythians and the Persian army pursuing them passed through the territories of the Melanchlaeni, Androphagi, and Neuri, before they reached the borders of the Agathyrsi, who refused to let the Scythian divisions to pass into their territories and find refuge there, thus forcing the Scythians to return to
Scythia with the Persians pursuing them.
Later history By the 4th century BC, most of the Melanchlaeni migrated to the south, where the settled around the Greek city of
Pontic Olbia, where the
Protogenes inscription, written sometime between 220 and 200 BC, mentioned them as the Saudaratae, which was a Hellenisation of their original Iranic name. According to the Protogenes inscription, the Scythians, the
Thisamatae, the Saudaratae, and the
Saii were seeking refuge from the allied forces of the
Celts and the Germanic
Sciri. The Saudaratae were still living around Pontic Olbia in the 1st century BC. ==Society and culture==
