Dear Markussep!
Surprising that you are so informed because many Dutchmans do not know that Hungary is exists.I copied these demographic data from the Hungarian wiki.
After the Košice attack, Hungary  sent a war message  to the Soviet Union(Košice attack was on 26th June, in 1941).The situation was normal before here. North komárom' population was Hungarian totally in that time.
Very much Jew lived in the North-Slovak city also ( about 89 000).The Jews 'mother language was Hungarian also. (talk • contribs)
