To resist external aggression successfully any state should keep the national unity. The lack of national unity at the time of the Ukrainian Revolution of 1917-1921 led to the loss of Ukrainian statehood. Consequently, it resulted in millions of losses from the Great Famine (Holodomor) of 1932-1933, repressions and wars.

The communist totalitarian regime tried to eradicate from the historical memory the events associated with the proclamation of the independence of the Ukrainian People’s Republic and its unification with West Ukrainian People’s Republic into one state.

The lasting Russian-Ukrainian war for the Ukrainians is a continuation of the centenary liberation struggle. Ukrainian military, as well as their predecessors 100 years ago, defend not only the independence but also the unity of Ukraine and integrity of its lands.
