Mikhail Kutuzov
Russian military commanders Dmitry Pozharsky (17th century) and Mikhail Kutuzov (19th century) credited invocation of the Virgin Mary through the icon with helping the country to repel the Polish invasion of 1612, the Swedish invasion of 1709, and Napoleon's invasion of 1812. The Kazan icon achieved immense popularity, and there were nine or ten separate miracle-attributed copies of the icon around Russia.
