Khan Jahan Ali Mazar
Hazrat Khanjahan Ali's shrine building
Hazrat Ulugh Khanjahan Ali was born in Delhi in 1369 AD to an aristocratic family.  His father's name was Akbar Khan and his mother's name was Ambia Bibi. It is believed that his ancestors were natives of Turkey. He acquired a deep knowledge of the Qur'an, Hadith, Sunnah and Fiqh.
Khanjahan Ali started his career as a commander in the army in 1389 AD. In a very short time he was promoted to the rank of Commander-in-Chief. In 1394, at the age of only 26/27, he joined the post of Jabitan (Governor) of Jainpur Province. Later, when Sultan Khanjahan led an invasion of Bengal with 60,000 well-educated advanced troops and another 200,000 troops, Raja Ganesha took refuge at Bhaturia in Dinajpur (citation needed). In 1418 Khanjahan took up position at Barbazar in Jessore and started propagating Islam in the south western part of Bengal.
