The article focuses on the hybrid conflict on the territory of Ukraine since 2013; its aim is to depict characteristic features of the hybrid war. The background of this article is the politics of Russia towards Ukraine since 1991, when this country gained its independence. In the opinion of Russians, Ukraine is a geopolitical misunderstanding, which openly violates the concept of “Russkiy Mir” (the Russian world). This means that Russia constantly aims at maintaining its sphere of influence in terms of the economy and politics in this region, as well as control over the military potential. Russia’s concerns mainly come from Ukraine’s desire to participate in some organisations, such as the EU or NATO. A real breakthrough was the Maidan Revolution and the annexation of Crimea, which resulted in the hybrid war in Ukraine.
