Mughal India was one of the three Islamic gunpowder empires, along with the Ottoman Empire and Safavid Persia. By the time he was invited by Lodi governor of Lahore, Daulat Khan, to support his rebellion against Lodi Sultan Ibrahim Khan, Babur was familiar with gunpowder firearms and field artillery, and a method for deploying them. Babur had employed Ottoman expert Ustad Ali Quli, who showed Babur the standard Ottoman formation—artillery and firearm-equipped infantry protected by wagons in the centre and the mounted archers on both wings. Babur used this formation at the First Battle of Panipat in 1526, where the Afghan and Rajput forces loyal to the Delhi Sultanate, though superior in numbers but without the gunpowder weapons, were defeated. The decisive victory of the Timurid forces is one reason opponents rarely met Mughal princes in pitched battle over the course of the empire's history. In India, guns made of bronze were recovered from Calicut (1504) and Diu (1533).
