Neo-Slavism was a short-lived movement originating in Austria-Hungary around 1908 and influencing nearby Slavic states in the Balkans as well as Russia. Neoslavists promoted cooperation between Slavs on equal terms in order to resist Germanization, pursue modernization as well as liberal reforms, and wanted to create a democratic community of Slavic nations without a dominating influence of Russia.
It was a branch of a larger and older Pan-Slavism ideology. Unlike Pan-Slavism, Neo-Slavism did not attach importance to religion and did not discriminate between Catholics and Orthodox believers, did not support the creation of a single Slavic state, and was mostly interested in a non-violent realization of its program.
