Scythia (Hindi: सीथिया, Persian: اسکیت ها or سکا ها), (/ˈsiθiə/; Ancient Greek: Σκυθική) was a multinational region of Central Eurasia in the classical era, encompassing parts of Pontic steppe, Central Asia, and Eastern Europe.
Its location and extent varied over time but usually extended farther to the west than is indicated on the map opposite.
The region known to classical authors as Scythia included:
- The Pontic-Caspian steppe: Ukraine, southern Russia and western Kazakhstan (inhabited by Scythians from at least the 8th century BC)
- Saka tigrakhauda, corresponding to parts of Central Asia, including Kyrgyzstan, southeastern Kazakhstan and Kashgar
- Scythia Minor: corresponding to the lower Danube river area west of the Black Sea, with a part in Romania and a part in Bulgaria
- The northern Caucasus area

The Scythians – the Greeks' name for this nomadic people – inhabited Scythia from at least the 11th century BC to the 2nd century AD.
Many different groupings of Scythian tribes include the following:
- Sakā Haumavargā
- Saka Tigrakhauda
Origin of Scythian
James Todd writes that the origin of the Scythic nations, as related by Diodorus; . when it will be observed the same legends were known to him which have been handed down by the Puranas and Abulghazi.
The Scythians had their first abodes on the Araxes. Their origin was from a virgin born of the earth of the shape of a woman from the waist upwards, and below a serpent (symbol of Budha or Mercury) ; that Jupiter had a son by her, named Scythes," whose name the nation adopted. Scythes had two sons, Palas and Napas (qu. the Nagas, or Snake race, of the Tatar genealogy ?), who were celebrated for their great actions, and who divided the countries ; and the nations were called after them, the Palians (qu. Pali ?) and Napians. They led their forces as far as the Nile on Egypt, and subdued many nations. They enlarged the empire of the Scythians as far as the Eastern ocean,
[p. 71]: and to the Caspian and lake Moeotis. The nation had many kings, from whom the Sacans (Sakae), the Massagetae ( Getae or Jats), the Ari-aspians (Aswas of Aria), and many other races. They overran Assyria and Media .  , overturning the empire, and transplanting the inhabitants to the Araxes under the name of Sauro-Matians. 
As the Sakae, Getae, Aswa, and Takshak are names which have crept in amongst our thirty-six royal races, common with others also to early civilization in Europe, let us seek further ancient authority on the original abodes.
Strabo  says : " All the tribes east of the Caspian are called Scythic. The Dahae next the sea, the Massagetae (great Gete) and Sakae more eastward ; but every tribe has a particular name. All are nomadic : but of these nomads the best -known are the Asii,  the Pasiani, Tochari, Sacarauli, who took Bactria from the Greeks. The Sakae (' races ') have made in Asia irruptions similar to those of the Cimmerians ; thus they have been seen to possess themselves of Bactria, and the best district of Armenia, called after them Sakasenae." .
shall not now stop to inquire, limiting our hypothesis to the fact of invasions, and adducing some evidence of such being simultaneous with migrations of the same bands into Europe. Hence the inference of a common origin between the Rajput and early races of Europe ; to support which, a similar mythology, martial manners and poetry, language, and even music and architectural ornaments, may be adduced.
Herodotus (iv. 12) says : " The Cimmerians, expelled by the Massagetae, migrated to the Crimea." Here were the Thyssagetae, or western Getae [the lesser Getae, Herodotus iv..22]; and thence both the Getae and Cimbri found their way to the Baltic. Rubruquis the Jesuit, describing the monuments of the Comani in the Dasht-i Kipchak, whence these tribes, says : " Their monuments and circles of stones are like our Celtic or Druidical remains " (Bell's Collection). The Khuman are a branch of the Kathi tribe of Saurashtra, whose paliyas, or funeral monumental pillars, are seen in groups at every town and village. The Chatti were one of the early German tribes. [Needless to say, the German Chatti had no connexion with the Kathi of Gujarat.]
James Todd writes that Of the first migrations of the Indu-Scythic Getae, Takshak, and Asii, into India, that of Sheshnag (Takshak), from Sheshnagdes (Tocharistan ?) or Sheshnag, six centuries, by calculation, before Christ, is the first noticed by the Puranas About this period a grand irruption of the same races conquered Asia Minor, and  eventually Scandinavia ; and not long after the Asii and Tochari overturned the Greek kingdom of Bactria, the Romans felt the power of the Asi, the Chatti, and Cimbri, from the Baltic shore.
If we can show the Germans to have been originally Scythae or Goths (Getes or Jits), a wide field of curiosity and inquiry is open to the origin of government, manners, etc. ; all the antiquities of Europe will assume a new appearance, and, instead of being traced to the bands of Germany, as Montesquieu and the greatest writers have hitherto done, may be followed through long descriptions of the manners of the Scythians, etc., as given by Herodotus. Scandinavia was occupied by the Scythae five hundred years before Christ. These Scythians worshipped Mercury (Budha), Woden or Odin, and believed themselves his progeny. The Gothic mythology, by parallel, might be shown
to be Grecian, whose gods were the progeny of Coelus and Terra (Budha and Ella). Dryads, satyrs, fairies, and all the Greek and Roman superstition, may be found in the Scandinavian creed. The Goths consulted the heart of victims, had oracles, had sibyls, had a Venus in Freya, and Parcae in the Valkyrie."
