Step 1: Maharana Kumbha (r. 1433–1468) of Mewar was a great warrior and builder; he also built Kumbhalgarh fort. Step 2: He defeated Mahmud Khilji of Malwa in 1437 (Battle of Sarangpur), and the Vijay Stambh at Chittorgarh was built (about 1440–1448) to mark this victory. Step 3: Ghori lived long before Kumbha, while Akbar and Babur came much later. So they cannot be the answer. Answer: Mahmud Khilji of Malwa.
