Like her predecessors, Catherine concerned herself with the Orthodox Christians under Ottoman rule; she sponsored the Orlov Revolt in the Morea during the Russo-Turkish War of 1768–1774, and invited many Greeks like Ioannis Varvakis to settle in Russia, mainly in Crimea and New Russia. She conceived that one of her grandsons, appropriately named Constantine, would become the first emperor of the restored Byzantium. Another important consideration was Russia's goal of free access to the Mediterranean Sea through the Bosphorus, which the Ottomans controlled.
