Eurasianism (Russian: евразийство, romanized: yevrazíystvo [jɪvrɐˈzʲijstvə]) is a socio-political movement in Russia that emerged in the early 20th century under the Russian Empire, which states that Russia does not belong in the "European" or "Asian" categories but instead to the geopolitical concept of Eurasia and the "Russian world", forming an ostensibly standalone Russian civilization. The ideology is geopolitical, similar to Atlanticism and Gulfism.
The first Eurasianists were mostly émigrés, pacifists, and their vision of the future had features of romanticism and utopianism. The goal of the Eurasianists was the unification of the main Christian churches under the leadership of the Russian Orthodox Church. A key feature of Eurasianism is the rejection of Russian ethnic nationalism, which seeks to build a pan-Slavic state. The Eurasianists strongly opposed the territorial fragmentation of the Russian Empire that had occurred due to the Bolshevik Revolution and the following civil war (1917–1923). They used their geo-historical theories to insist on the necessity of the geopolitical reconstruction of the Russian state as a unified Eurasian great power. Unlike many of the White Russians, the Eurasianists rejected attempts for Tsarist restoration.
