ABSTRACT This article explores classical eurasianism as a specific branch of russian philosophy abroad in the early twentieth century, the ideas of which remain relevant and are currently revived by its followers. The author highlighted the main features and ideas of classical eurasianism (the idea of Russia-eurasia as a unique developmental space, the doctrine of sobornost, and the philosophy of an organizational idea) and compared them with the theories of L. N. Gumilyov and A. G. Dugin. However, the teaching of L. N. Gumilyov and the Neo-eurasianism of A. G. Dugin do not possess the original philosophical component of classical eurasianism.
