Ki a fenék voltak a szlovákok ősei? Tatárjárás utáni szláv migránsok leszármazottai?

The simple political interests and the typical chauvinist national narcissism created the so-called NATIVIST theories in the era of the national awakening. In the 19th century , it was politically very hard for the Slovaks to build any territorial demands and claims on the basis of their late medieval era migratory past, thus the early Slovak nationalists had to fabricate a NATIVIST autochonist fairy tale history to create a national identity. Despite their extreme level of wannabee-ist tales and stubborn wishful thinking, the modern Slovaks are not really related to local ancient Slavs.

Slovak is one of the youngest ethnonym in Europe, the "Slovak" term was born only in the 15th century, in the early modern period. Without own ethnonym, we can't even speak about identity or ethnicity. Unlike the Czechs, Croats, Polish (some white Croats), Serbs etc...who had real ethnonyms, their late born ethnonym the "Slovak" is not a real ethnonym , its meaning: "something Slavic language speakers". Nomen est omen. No wonder: Slovaks were early modern period mixture of immigrants: Czech Hussites from the N-west, Polish immigrants from the north, Local Hungarians, nomadic Vlach settlers in Eastern Slovakia, Rusyn people in the east, and some German settlers. This modern mixture had a clear impact on various Slovak "dialects". In the reality this were not dialects but rather different languages. This mixature is mirrored in their many old languages Until the birth of the unified "Central Slovak" language in the 19th century, some of the Slovak dialects were closer to Czech language, others were closer to Polish language another dialects were closer to the Rusyn language. So Slovaks did not have even a common mutually intelligible language (which is a corner point of a real nation or an ethnic group) until the Slovak linguistic reforms of the 19th century.

The common unified mutually intelligible Slovak language was spread by the Czechoslovak school system during the interwar period and the communist era, which remained the central policy and goal of the Czechoslovak governments.

The Slovak “ethnic group” is a young modern artificially and politically designed/MANUFACTURED product instead of real natural/organic historic development.
