Ryazan Governorate
It was first mentioned in 1546 among other fortified towns in the periphery of the Grand Duchy of Moscow. It was inhabited by the Streltsy, cannonmakers, and carpenters, who formed "slobodas" around the town. In 1618, Mikhaylov withstood a ten-day siege by the Polish army. In 1708, the town became a part of Moscow Governorate and then of Ryazan Vice-Royalty and Ryazan Governorate.
