This is the argument to the development of which I have devoted the following pages. The book seems to me naturally to divide itself into three parts. To Bahar, as the developer of the idea of the invasion and conquest of India, I have devoted the first part. He was a remarkable man, and he would have been remarkable in any age. When he died, at the early age of forty-eight, he left behind him a record which may be read with interest and profit even at the close of this nineteenth century. It has seemed to me the more necessary to devote a considerable space to him inasmuch as the reader will not fail to discern, in the actions of the grandson, the spirit and energy and innate nobility of character of the grandfather. Of Humdyun, whose life properly belongs to the first part, I have written as much only as seemed to me necessary to illustrate the cause of his fall, and to describe the early days of the hero of the book, who was born in Sind, during the father’s flight from India.
