  In Ukrainian history, the period of the Russian Revolution and Civil War from 1917 to 1921 is regarded as the period of the National Liberation Movement. After the Russian Empire and the Civil War, the Central Rada, the representative body of Ukrainians, was formed in Kiev. After negotiations with the Provisional Government, the General Secretariat of the Central Rada was recognized as the governing body of Ukraine. After the Petition, the Central Rada declared the formation of the Republic of Ukraine consisting of the Ukrainian territories belonging to the Ukrainians, and issued the Fourth Universo (Declaration) in January 1918, declaring the independence of Ukraine.

　Then, in April 1918, a conservative coup d'état established the State of Ukraine, commonly known as the Hetman State, with Hetman as its monarch. However, an uprising by the Central Rada overthrew the Ukrainian state in December and restored the Ukrainian People's Republic. The so-called Directrician regime was established. During this period, despite the intervention of reactionary forces and foreign powers, the Ukrainians struggled to maintain their own independent state, which they had won in the Fourth Ukrainian War, and to build Ukraine. However, in 1921, Ukraine suffered a defeat at the hands of the Soviet Red Army and became part of the territory controlled by the Soviet Union. the Russo-Ukrainian War, which broke out on February 24, 2022, has a complicated history of the ⺠national liberation movement.
