Once a person starts to study the 250-some years of the Mamluk Era in Egypt and Syria (1250-1517), one characteristic of that period stands out immediately - the very unusual polarization of its society. A predominantly Arabic population was dominated by a purely Turkish-born elite of manu-mitted military slaves who sought to regenerate themselves continuously through a self-imposed fiat. The only person who could become a Mamluk was a Turk who had been born free outside the Islamic territories as a non-Muslim, then enslaved, brought to Egypt as a slave, converted to Islam, freed, and finally, trained as a warrior. Only those who met these prerequisites were members of the ruling stratum with all the concomitant political, military, and economic advantages. On this historically unique model of a society, Stephan Conermann has published a series of seminal articles. In this edited volume the reader gets an excellent introduction to some of the central issues of the ongoing research on the Mamluk history and society.
