Iltutmish, who was the sultan of Delhi from 1211 to 1236, established a center of learning in Patna. Patna, located in present-day Bihar, was an important city during the medieval period and served as a center of education and culture. This center of learning established by Iltutmish likely included schools and institutions where scholars and students could engage in the study of various subjects such as languages, sciences, philosophy, and religion. It is important to note that Patna`s reputation as a center of learning continued to grow even after Iltutmish, with many renowned scholars and intellectuals being associated with the city in the following centuries.
