"Under the rule of Catherine the Great, Russia reclaimed all of its historical lands, including in the south and west. This all lasted until the Revolution. Before World War I, the Austrian General Staff, relying on the ideas of Ukrainianization, started to actively promote the ideas of Ukraine and the Ukrainianization. Their motive was obvious. Just before World War I, they wanted to weaken the potential enemy and secure themselves favourable conditions in the border area. So this idea which had emerged in Poland that people residing in that territory were allegedly not really Russians, but rather belonged to a special ethnic group, the Ukrainians, started to be promoted by the Austrian General Staff too. As far back as the 19th century, theorists calling for Ukrainian independence appeared. All those, however, claimed that Ukraine should have a very good relationship with Russia. They insisted on that. After the 1917 Revolution, the Bolsheviks sought to restore the statehood, and the Civil War began, including the hostilities with Poland. In 1921, peace with Poland was proclaimed, and under that treaty, the right bank of the Dnieper River once again was given back to Poland."
