Read the following passage and answer the questions that follow.
A different kind of historian wan Barani, whose work, written in 1357, is a history of the Delhi Sultanate from the point where Minhaj Siraj ended his narrative. Barani is different from his peers, especially because he takes up aspects of life other than dynastic and political, such as economic, social, intellectual and religious. He is also novel in that he applies to events a distinct historical theory of his own. This theory was premised on a triangular relationship between despotic monarchy, the established nobility and upstarts from the non-aristocratic classes.
