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.
