From the 18th century on, Ukraine became known in the Russian Empire by the geographic term Little Russia. In the 1830s, Mykola Kostomarov and his Brotherhood of Saints Cyril and Methodius in Kyiv started to use the name Ukrainians.

The Soviet fleet in Crimea was also in contention, but a 1997 treaty allowed Russia to continue basing its fleet in Sevastopol. In 2014, the peninsula was occupied by Russian forces and annexed by Russia, but most countries recognise Crimea as Ukrainian territory.

Putin espoused irredentist views challenging Ukraine's right to exist, and falsely claimed that Ukraine was governed by neo-Nazis persecuting the Russian minority. He said his goal was to "demilitarise and denazify" Ukraine.
