Mahmud Shah, the fourth sultan of the Jaunpur sultanate, had been successful in his conquest of Chunar, but had failed to capture Kalpi.

He has also conducted campaigns against Bengal and Orissa.

In 1452, he had invaded Delhi but had been defeated by Bahlul Lodi.

He had made a subsequent attempt to conquer Delhi and marched into Etawah.

Finally, he had agreed to a treaty which accepted the right of Bahlul Lodi over Shamsabad.

But when Bahlul had tried to take possession of Shamsabad, the forces of Jaunpur had opposed him.

At this juncture, Mahmud Shah dies and is succeeded by his son Bhikhan in 1457, who had assumed the title of Muhammad Shah, made peace with Bahlul Lodi and recognized his right over Shamsabad.

He picked up a quarrel with his nobles.

In 1458, while Muhammad Shah is in Kanauj, his brother proclaims himself as Sultan Hussain Shah in Jaunpur; Muhammad Shah is soon killed by his army.
