Turkish notables settled in the larger cities (Plovdiv, Sofia, Varna, etc.), while peasants from Anatolia arrived in the Ludogorie and the Rhodopes. Many Orthodox Christians and Paulicians converted to Islam, often voluntarily due to the peculiarities of the Ottoman millet system, but sometimes forcefully. After the Liberation of Bulgaria in 1878 many Muslims were massacred and forcefully deported to the remaining Ottoman territories.
