What was one of Ivan III's major achievements?

One of Ivan III's significant achievements was making Moscow the capital of Russia. This move was pivotal in uniting the various principalities of Russia under a centralized authority. By establishing Moscow as the political and cultural center, Ivan III laid the groundwork for the future Russian state. His reign saw the expansion of Moscow’s territory, as he successfully annexed surrounding regions and asserted control over former Kievan Rus territories, further enhancing Moscow's status. This centralization helped to strengthen the Russian identity and promoted the idea of Moscow as the "Third Rome," a concept important for the Russian Orthodox Church and the broader notion of Russian sovereignty. This strategic decision set the stage for Moscow's prominence and influence in the region for centuries to come.
