The Kazan Orphan is a rogue pretending to be a poor man. He speculates on his alleged plight for material gain.
A has gone this expression since the time of Tsar Ivan the Terrible. In October 1552, Kazan fell under the pressure of the Russian army, Khan Ediger was captured, his soldiers were executed, and some of the loyal Kazan residents were resettled outside the walls of the posad, on the shores of Lake Kaban, laying the foundation of the Old Tatar settlement of Kazan.
To preserve the status and prosperity of the Tatar nobility, the murzas (princes) in every possible way pleased the new ruler. They went into the service and even voluntarily adopted Christianity, for which they were encouraged by the tsar: he handed them gifts and brought them closer to his court. The people mockingly called such princes "Kazan orphans", because in the presence of Ivan Vasilyevich they made every effort to be pity, trying to achieve by this as much condescension and awards as possible.
According to other sources, the expression "Kazan orphan" appeared after the brutal extermination of the recalcitrant part of the population of Kazan by the troops of Ivan the Terrible. After the capture of Kazan, the entire Middle Volga region was annexed to Russia, and the orphans, whose number increased many times over, began to be called Kazan.
