I wonder who is this. Weird because both featured months ago, quite sudden their appearance. Too consistent to be simple proxy. Maybe they really are but I'm skeptical.
Pls, do not misunderstand me, I'm glad if someone else posts beside me.

Anyway.
Onto the Great Hungarian Plain among us three groups of steppe people were settled. The aforementioned jász (Yaziges), besenyő (Pecheneg), and kun (Cuman), the latter two of Turkic origin. They don't exists today as real ethnicities, only geographical regions and settlements preserve their names. Some Hungarians might identify themselves as such, or hold the belief of their ancestry.
Weird case of the Avars, archaeology revealed they seen the Hungarian Conquest of the Carpathian Basin, but we don't know about their further fate (well they were assimilated), and no place or geographical names preserve their presence. This led to the hypothesis, that the "Avars" living here when the Magyars of Árpád arrived were Hungarians, who slowly migrated into the Avar Khaganate and surpassed and replaced the original population.
A fourth group of Turkic people arrived with the Hungarians, the kabar tribes (sometimes written as kavar) who were subjects of the Khazar Khaganate, a subgroup of the Khazars. Sometimes it's speculated that our third Christian king, Aba Sámuel, was from the Kabars - who was related to the Árpáds via marriage.

There are the Székelys ofc, who are Hungarians. Some researchers say they have Turkic origins, but no evidence exist that they spoke any other language than Hungarian. Usually it isn't disputed that they joined later, most likely after the Conquest, since they already lived here, and they were used as border guards since it was customary for steppe people to use freshly incorporated tribes to use as such. Well, they say they did.
