After 1552 the khanate was governed by Kazan Palace's Office formed in Moscow. In 1555 a bishop was appointed in Kazan with a mandate to baptize the Idel-Ural peoples. Many churches and monasteries were built, and Russian peasants and craftsmen were resettled within Tatarstan. At the same time ethnic Tatars were removed from Kazan proper as well as regions close to rivers and roads. Under pressure from the Russians many Tatars emigrated to the Upper Kama, Trans-Kama area, Bashkortostan, the Urals and Siberia during the 16th and 17th centuries. The result was a decline in agriculture, industry and commerce throughout the region. The local population was forced to pay the yasaq tax. Some part of the Tatar nobility were included in the nobility of the Russian Empire; many underwent baptism to keep their privileges.
