Alauddin helped India fight against the Mongol empire
The most interesting fact about Alauddin Khilji is that he helped India fight against the Mongol empire. The Khilji dynasty was not only renowned for its ferocity and irreligion; they were also essential in protecting India against Mongol incursions. India succeeded particularly under Alauddin's leadership. Because the Mongols were divided into various tribes and invaded the empire in various locations, the war was complicated.
However, Alauddin Khilji was able to stop it by employing his military prowess and ferocity, protecting the Indian people and their way of life from foreign invaders. Khilji was able to defeat the Mongols not once, not twice, but five times. He also avoided losing a sixth time, despite being caught off guard as the Mongols launched a ferocious onslaught.
The first invasion effort, which encompassed 100,000 horsemen, took place in 1298 CE. In addition to completely defeating the Mongols, Alauddin dispatched an army under the command of his brother Ulugh Khan and the general Zafar Khan. This army also captured 20,000 prisoners who were later executed. The Mongols invaded once more in 1299 CE, this time in Sindh, and took control of the fort of Sivastan. In order to overcome them and retake the fort, Alauddin sent Zafar Khan, who succeeded even without the use of siege equipment.
