Before the establishment of independent
Czechoslovakia in 1918, Kolbasov was part of
Zemplén County within the
Kingdom of Hungary. In 1939, it was for a short time part of the
Slovak Republic. As a result of the
Slovak–Hungarian War of 1939, it was from 1939 to 1944 again part of
Hungary. On 26 October 1944, the
Red Army entered Kolbasov and it was once again part of Czechoslovakia. Several Jews were murdered here by the
Ukrainian Insurgent Army (UPA) on 8 December 1945, the last night of
Chanuka. ==Geography==
