Day of Ukrainian Cossacks (14/10)

Every year on October 14, Ukraine celebrates the Day of the Ukrainian Cossacks (in Ukrainian, the Day of the Ukrainian Cossacks) - a holiday dedicated to the day of the Intercession of the Most Holy Theotokos (since the Mother of God is considered the protector and patroness of the Cossacks) and established by Decree of the President of Ukraine No. 966/99 of August 7, 1999, taking into account the historical significance and merits of the Cossacks to the Fatherland in the establishment of Ukrainian statehood and its significant contribution to the modern process of creating and developing independent Ukraine.

The origin and formation of the Ukrainian nationality took place in the 12th-15th centuries on the basis of the southwestern part of the East Slavic population, which was previously part of Kievan Rus (9th-12th centuries). On the basis of the ancient Russian nationality, three East Slavic peoples were formed - Ukrainian, Russian and Belarusian.

Beginning in the 13th century, Ukrainians were subjected to Hungarian, Lithuanian, Polish and Moldavian conquests. From the end of the 15th century, the raids of the Tatar khans, who had established themselves in the Northern Black Sea region, began, accompanied by mass captivity and theft of Ukrainians.
