However, the Russian Empire often claimed Pan-Slavism as a justification for its aggressive moves in the Balkan Peninsula of Europe against the Ottoman Empire, which conquered and held the land of Slavs for centuries. This eventually led to the Balkan campaign of the Russian Empire, which resulted in the entire Balkan being liberated from the Ottoman Empire, with the help and the initiative of the Russian Empire. Pan-Slavism has some supporters among Czech and Slovak politicians, especially among the nationalistic and far-right ones, such as People's Party - Our Slovakia.
