 The process itself is limited mostly to Slovakia, where Slovaks constitute the absolute majority by means of population and legislation power as well.Slovakization is most often used in relation to Hungarians, who constitute the most prominent minority of Slovakia, but it also affects Germans, Poles, Ukrainians, Rusyns (Ruthenians), and Jews.The process of slovakization was present in the Kingdom of Hungary presumably ever since the appearance of the Slovak nation itself, but up until the foundation of Czechoslovakia the process was entirely voluntary.
