This study seeks to analyze and understand the Russian propaganda before and after the full-scale invasion of Ukraine. 15th of October 2021 to the 28th of February 2022 is the chosen research period, mainly because of the importance to get an understanding of how Kremlin used its propaganda machine to first justify the invasion and then legitimizing it after 24th of February. The study aims to shed light on how the propaganda can be understood from the perspective of the theories classical realism and authoritarian propaganda. Also, from a more general perspective to recognize what truly pervades the Russian propaganda during the period. The result reveals that the propaganda is strongly shaped by realistic beliefs regarding Russia’s national security in relation to the supposed threat coming from Kyiv and the West. It also shows that the propaganda is heavily restricted to the Russian authorities, seeing that it aims to create a reality where the western hegemony is in the wrong, while the Russian society is an idealistic alternative. Therefor the propaganda creates an image that Russia did not have any other choice than to invade Ukraine, to save it from Nazism and the presumed disastrous western civilization.
