The Khilji Dynasty expanded under Alauddin’s rule
Alauddin Khilji was regarded as the Khilji Dynasty's most powerful leader throughout its 30-year rule. Alauddin would rule for twenty of these years from his seat in the Delhi Sultanate, from 1296 to 1316. When he was at the height of his authority, Alauddin's armies ruled over large areas of Afghanistan, Bihar, Kashmir, and Karnataka.
Alauddin waged wars nonstop for 15 years. Gujarat, Ranthambhor, Chitor, and Rajasthan, western Hindu kingdoms, had fallen by 1303. He stopped the Mongols' progress into India during the course of the following three years and brought calm to India's northwest frontier. He conquered central India in 1305, bringing Malwa, Ujjain, Chanderi, and Mandawar under his rule. He made another assault at Devagiri two years later, and by 1309 his army had arrived at Cape Comiron, which is the southernmost point of India.
Alauddin Khilji was Delhi's richest sultan in history by 1311! He even issued coins with his name as Alexander II on them as he came up with the idea of founding a new religion and conquering the entire world. However, his advisors convinced him against going after such self-glorification.
