of migration by other Russian and non-Muslim populations into Muslim lands displaced many Muslims, making them minorities in places such as some parts of the South Ural region and encouraging emigration to other parts such as the Ottoman Empire and neighboring Persia, and almost annihilating the Circassians, Crimean Tatars, and various Muslims of the Caucasus. The Russian army rounded up people, driving Muslims from their villages to ports on the Black Sea, where they awaited ships provided by the neighboring Ottoman Empire. The explicit Russian goal involved expelling the groups in question from their lands. They were given a choice as to where to be resettled: in the Ottoman Empire, in Persia, or Russia far from their old lands.

The trend of Russification has continued at different paces in the rest of Tsarist and Soviet periods, so that more Tatars lived outside the Republic of Tatarstan than inside it.

Communist rule oppressed and suppressed Islam, like other religions in the Soviet Union. Many mosques (for some estimates, more than 83% in Tatarstan) were closed. For example, the Märcani Mosque was the only acting mosque in Kazan at that time. Islam in the post-Soviet period There was much evidence of official conciliation toward Islam in Russia in the 1990s.
