The dataset includes fifteen programmes of the festival, which has been held annually in the border regions of Ukraine, Belarus and Russia since at least 1975.
Until 2005 the festival was called Friendship, and since 2005 the Russian organisers have designated it as the Slavic Unity Festival, a name that was never adopted by Ukraine.
After Russia's annexation of Crimea and the outbreak of armed conflict in Donbass in 2014, Ukraine withdrew from participation. The dataset with programmes before and after Ukraine's withdrawal clearly demonstrates how new narratives were added to the festival first in 2005 and then again after 2014.
