Why did the Russia want to unite the Slavic people?

Russia sought to unite the Slavic people primarily to enhance its influence and strengthen its geopolitical position in Eastern Europe. By promoting Slavic unity, Russia aimed to foster a sense of shared identity and cultural heritage, which could serve as a counterbalance to Western powers. Additionally, this unification was seen as a way to spread Russian nationalism and Orthodox Christianity, reinforcing Russia's role as a leader among Slavic nations. Ultimately, such efforts were also driven by historical, political, and strategic interests.
