Russia's boundaries expanded primarily under the leadership of Tsar Peter the Great in the early 18th century, as he sought to modernize the country and gain access to warm-water ports. His military campaigns against Sweden and the establishment of Saint Petersburg significantly expanded Russian territory. Additionally, Catherine the Great furthered this expansion in the late 18th century through successful wars against the Ottoman Empire and the partitioning of Poland. These leaders played crucial roles in shaping the vast expanse of Russia's territory.
