The Ottoman Empire would face the problem of immigration as a result of the wars by the end of the 18th century. Between 1774 and 1920, population migration occurred from Crimea to the Ottoman geography and in 1783 and 1860 massive population migration occurred. The most important reason for these migrations is the fact that Turks could not keep the values of Muslim Turkish society alive. Because of the population migrations to Rumeli and Anatolia, Turkish population in Crimea came to an end. While the population of the Crimean Khanate was 3,5 million, according to the Russian statistics, the population of the Crimea province called Tavrida decreased to 664.582. The number of Turkish population decreased to 35,1% (190.000). If the migrations had continued, Turkish entity in Crimea could have disappeared on the map. İsmail Gaspıralı tried to prevent the migration from Crimea to Turkey in order to avoid the possibility of the disappearance of Turkish entity in Crimea. Besides, he was trying to prevent the massive habitation of Slavic communities to Crimea. According to İsmail Gaspıralı, these migrations and habitation activities would cause the disappearance of Turkish entity and would not contribute much to the Ottoman Empire economically. In this study, Gaspıralı’s actions are highlighted and discussed
