The date, June 25, was proposed by activists of public associations in the late 90s of the 20th century, when they realized the loss of the connecting thread between the Slavic peoples due to the collapse of the USSR. The creative All-Union festival “Small Motherland”, first organized in 1957, was taken as a basis. After 1991, with the further isolation of countries from each other, the Slavic peoples also began to move away, because the states became independent.
