Radical nationalism in Russia

Radical nationalism in Russia refers to some far-right and some far-left extremist nationalist movements and organizations. Of note, the term "nationalist" in Russia often refers to radical nationalism. However, it is often mixed up with "fascism" in Russia. While this terminology does not exactly match the formal definitions of fascism, the common denominator is chauvinism. In all other respects the positions vary over a wide spectrum. Some movements hold a political position that the state must be an instrument of nationalism (such as the National Bolshevik Party, headed by Eduard Limonov), while others (for example, Russian National Unity) resolve to vigilante tactics against the perceived "enemies of Russia" without going into politics.
