Russian Monarchist Union (ru|Русский монархический союз|Russkii Monarkhicheskii Soiuz) was a Russian monarchist right-wing nationalist organisation, founded in February 1905 in Moscow. Until 1907, it was known as the Russian Monarchist Party (ru|Русская монархическая партия|Russkaia Monarkhicheskaia Partiia).
The party was founded by Vladimir Gringmut (ru), reactionary editor of the periodical Moscow News (Moskovskiye vedomosti), in February.[1]
It advocated the reestablishment of a powerful autocratic rule, martial law, and suppression of Jews, who they claimed were mainly the instigators of the revolutionary disorders.[1] It also stood for local self-government, public education, freedom of the press, and improving workers' and peasants' conditions. It had the following internal enemies: constitutional democrats, socialists, revolutionaries, anarchists, and the aforementioned Bundists.[2]
