Conversion to Islam (or Islamization) was a social process of utmost importance to Islamic society throughout its history. Nevertheless, the relation between the expansion and establishment of Dar al-Islam and conversion to Islam is thought to be so axiomatic by scholars of medieval Islamic history that few have actually ventured to investigate conversion as a distinct process. Scholarly works dealing with the topic in pre-Ottoman times are so sporadic that it would not be an exaggeration to say that the study of conversion in medieval Islamic social history is still in its infancy.
