500 AD? The first Turkic state, the Göktürks, was establsihed in 552 AD.
552 is correct - I didn't look it up before my post, as it wasn't an answer yet.
However, Gokturks are the first
fully Turkic state. Before that there were confederations of Huns, in which Turkic tribes were most numerous (others include Mongol, and Tatar...). These were Great Huns (Xiongnu) in 2nd and 3rd centuries BC. Later were West Huns (Attila's bunch) in 5th century, which was again a mix (Magyar, Bulgar, Tatar but probably much less Turkics than the previous). Then in 5th-6th centuries (including 500AD for Abaddon) there are the White Huns (Hephthalites) who were a mix of Turkic tribes, Persians, Afghans. If you go way back, the east bit of Scythians - as well as their descendents (Yakuts) today also spoke Turkic languages (But most Scythians spoke Indo-Europaic.
The problem of identifying who is who in Asian Steppes arises because Turkic and Tatar tribes migrated all over the place back and forth, throughout the history. That's why they ended up so scattered in modern times. You can safely say that some Turkic peoples have passed over any given piece of land between Adriatic Sea and Wall of China, at some point in history. The name "Tu-ruk" appears in Chinese scripts before Gokturks. But you are correct that Gokturks are the first obviously Turkic civ.
Actually, I've been wondering what the heck was the ethnic distrubition of Anatolia before Manzikert.
A soup.
A ridiculous number of tribes passed through today's Turkey, so it is complicated.
First there were Hattis. Then Hittites came from the north. Then Phrygians, Galatians, Lydians, Greeks, Cimmerians (Conan’s tribe), Persians, Romans…In the east Urartians, Hurrians, Mitannis, Assyrians, Armenians… Finally Arabs and Turks… totally like vegetable soup.
Before Battle of Manzikert it would be Byzantine (i.e. mainly Greek) in the west; Armenian and Kurdish (they might have had a different tribe name then) in the east, with some Arabs (it was under the caliphate’s control afterall). And Turks were scattered in lesser numbers all over the place (yep, Turks came to Turkey a couple of centuries earlier than the coming of the Turkish rule, in the form of tribes that send their warriors as mercenaries, passed from the caliphate. If I remember correctly, there were some Turkic mercenaries on the Byzantine side in the battle, but they switched sides.).
Also remember that Manzikert was before the crusades were even thought of. So before Manzikert, it wouldn’t be weird to find Arab trade caravans in Byzantine Empire.
So for Abaddon, in 500 AD;
Turkic tribes were a scattered bunch in central Asia, with no unifying khan or khaqan. (So probably it would be a white area in a NES map). Religion was shamanism, most commonly a pantheon under the head deity named Gok-tengri (Sky-god). That’s probably one of the reason Turks would call their first empire “Sky-Turks” half a century later (also note that many Turkish flags have light blue in their flags, including Seljuk Empire, as well as today’s Kazakhstan, Azerbaijan, and Iraqi Turkmen). They had their own alphabet since long ago, but not a developed literature (you can’t carry scrolls and books when you are a nomad in harsh climate I suppose – survival resources take precedence). The written stuff that survived to our time are from tombs or monoliths, the most famous ones being the Orhun inscriptions (in today’s central Mongolia), which talk about history of some Gokturk rulers.
All of Anatolia (it seems weird to me to call it Turkey before Turks arrive there) was under Byzantine Empire, and a strong one at that (golden age perhaps). Almost all inhabitants were orthodox christians at this time (seven churches of Asia, mentioned in the Bible, are all in Turkey).
