伊凡三世
Residents of Novgorod knew of the White Sea from at least the 11th century and rapidly explored its commercial significance for navigation and its coastal forests rich in fur animals. One of the earliest settlements near the sea shores grew up in the late 14th century at Kholmogory, on the Northern Dvina. From there, in 1492, a merchant fleet laden with grain and carrying ambassadors of Ivan III of Russia sailed to Denmark, marking the establishment of the first international seaport in Russia.
