The Székely territories came under the leadership of the
Count of the Székelys (Latin:
Comes Siculorum), initially a royal appointee from the non-Székely Hungarian nobility who was de facto a
margrave; from the 15th century onward, the
voivodes of Transylvania held the office themselves. The Székelys were considered a distinct ethnic group (
natio Siculica) and formed part of the
Unio Trium Nationum ("Union of Three Nations"), a coalition of three Transylvanian
estates, the other two "nations" being the (also predominantly Hungarian) nobility and the
Saxons (that is,
ethnic German burghers). These three groups ruled Transylvania from 1438 onward, usually in harmony though sometimes in conflict with one another. During the
Long Turkish War, the Székelys formed an alliance with Prince
Michael the Brave of
Wallachia against the army of
Andrew Báthory, recently appointed Prince of
Transylvania. In the
Middle Ages, the Székelys played a role in the defense of the
Kingdom of Hungary against the
Ottomans in their posture as guards of the eastern border.
Nicolaus Olahus stated in the book
Hungaria et Athila in 1536 that
"Hungarians and Székelys share the same language, with the difference that the Székelys have their own words specific to their nation." The people of Székelys were in general regarded as the most Hungarian of Hungarians. In 1558, a Hungarian poet, Mihály Vilmányi Libécz voiced this opinion, instructing the reader in his poem that if they had doubts about the correctness of the Hungarian language:
"Consult without fail the language of the ancient Székelys, for they are the guardians of the purest Hungarian tongue".
Origins The origin of the Székelys has been much debated. It is now generally accepted that they are descendants of Hungarians. The Székelys have historically claimed descent from
Attila's
Huns After the theory of Hunnic descent lost scholarly currency in the 20th century, two substantial ideas emerged about Székely ancestry: Researchers could not prove that Székelys spoke a different language. In this case, their strong cultural differences from other Hungarians stem from centuries of relative isolation in the mountains. • Others suggested Turkic origin as
Avar,
Kabar or
Esegel-Bulgar ancestries. • According to a new model, the Székelys are the descendants of those "wanderers" who ran away from the feudal state and the landlord system mostly during the 11th and 12th centuries. These parasocial groups settled in border regions and hard-to-reach places (forests, swamps) down where the institutional vacuum allowed them to found independent communities. The Hungarian kings reintegrated these groups into the kingdom's society from the beginning of the 12th century. The Hungarian
Hajdúk,
Cossacks,
Maroons, and
ʿApiru offer an analogy for the process. Some historians have dated the Székely presence in the Eastern
Carpathian Mountains as early as the fifth century, confederation during the so-called
Dark Ages, but this does not mean that they were ethnically Avar. Research indicates that Székelys spoke
Hungarian. Toponyms at the Székely settlement area also give proof of their Hungarian mother tongue. The Székely dialect does not have more Bulgaro-Turkish loanwords derived from before the
Hungarian conquest of the Carpathian Basin than standard Hungarian does. Even if the Székelys had been a Turkic stock, they would have had to lose their original vernacular at a very early date. ==Genetics==
