 Bosnia lacked a strong Christian church organization to command a strong following—the result of a scarcity of priests and competition among the Orthodox and Roman Catholic Churches and schismatic Bosnian Church, which collapsed shortly before the Ottomans arrived.This left most people religiously unengaged and receptive to the appeal of Islam’s institutions.This receptiveness was aided by the development among many people of a kind of folk Christianity centered on various practices and ceremonies that was adaptable to a form of folk Islam popular at the time of the invasion.
