Delhi Sultanate The rise of the Delhi Sultanate in India was part of a wider trend affecting much of the  Asian  continent, including the whole of southern and western Asia: the influx of  nomadic   Turkic peoples  from the Central Asian  steppes . This can be traced back to the 9th century when the Islamic  Caliphate  began  fragmenting  in the  Middle East , where Muslim rulers in rival states began enslaving non-Muslim nomadic Turks from the Central Asian steppes and raising many of them to become loyal army slaves called  Mamluks . Soon,  Turks were migrating  to  Muslim lands  and becoming  Islamicized . Many of the Turkic Mamluk slaves eventually rose to become rulers and conquered large parts of the  Muslim world , establishing Mamluk Sultanates from  Egypt  to present-day  Afghanistan , before turning their attention to the Indian subcontinent.
