Muslims of Indian origin

Got a chance to lay my hands on a (nice) book about the "Muslims of Indian Origin during the Sultanate period". I could not stop myself from going through it "cover to cover". I under stand that no one in the present day generation is interested in the related issues. The matter is highly academic but can be of immense importance for methodology to be employed for the study of emergence of the attitudes of the Indian Muslims and the attitudes of the early converts. It is a very nice account of the developments in the medieval period, collected from various authentic sources.
A number of incidents of interest lay scattered in the stories recorded by the contemporary sources, including travellers. These incidents will certainly be of some interest for any one interested (to any extent) in history of this era. The author has tried to take back the reader to the 11th, 12th, 13th and 14th centuries.All the Khaljis, Aibaks and Saiyyads etc. pass marching by your side. Khusrau and Barani try to drive home their theories about the Turks, Afghans and Arabs.
