Scythian post
There was the entire Scythia culture/region/people, all of which shared the same name, who lived in most of modern-day Russia. Then this was loosely categorized into Saka in the east, and Sarmatia in the west, although during the Achaemenid Empire’s zenith, everyone called the nomads in the North “Scythians.” Only when the Seleucids came to power did the phrase “Saka” become popularized among contemporaries to describe the marauding eastern Scythians. Then in the west, the Scythians were known as the Sarmatians, which were easily defined into a multitude of different tribes by ancient Greek authors such as the Saii, Siraces, Iwzag, etc. The Sakans were just clumped into one big “Saka” horde. I don’t even know if the Sakans themselves called themselves “Sakans.” It might’ve been a name given to them by “civilized” people, like how Columbus straight up dubbed the Native Americans “Indians.” Unlike the Native Americans, however, the Sakans might have actual biological immunity to all known diseases, and thus responded to their civilized neighbor’s incompetent naming by plundering and destabilizing their empires for centuries. Back to the west, some Sarmatians tribes were recorded as having waged a brutal war, bordering on genocide, against ANOTHER separate, distinct Scythian group, which was known as… Scythians. I’m not kidding, they were known as just the “Scythians” by the Greeks and used to inhabit the area around the Crimean Peninsula. This Scythian subgroup cannot be further subdivided like the Sarmatians. It’s like this Scythian subgroup are indivisible quarks and the Sarmatians are protons, but this Scythian subgroup does not combine in triplets to form Sarmatians - ok, let’s just end this tangent. The Scythians (the subgroup) were pushed out by the Scythians (the western ones, but excluding the subgroup) into modern-day Romania, where they established a small kingdom called… Scythia.
