As a result of the Siege of Kazan in 1552, Tsar Ivan the Terrible conquered the city. During the subsequent governorship of Alexander Gorbatyi-Shuisky, most of the Kazan's Tatar residents were forcibly Christianized or deported, the Kerashen Tatars. Mosques and palaces were ruined. The surviving Tatar population was moved to a place away from the city and this place was forcibly settled by Russian farmers and soldiers. Tatars in the Russian service were settled in the Tatar Bistäse settlement near the city's wall. Later Tatar merchants and handicraft masters also settled there. During this period, Kazan was largely destroyed as a result of several great fires. After one of them in 1579, the icon "Our Lady of Kazan" was discovered in the city.
