Ancient Indian universities, such as Nalanda and Takshashila, were prominent centers of learning from around the 5th century BCE to the 12th century CE. These institutions attracted students from various regions, including China, Korea, and Tibet, offering a wide range of subjects like philosophy, mathematics, and medicine. The universities were known for their rigorous academic standards and diverse curricula. Nalanda, for instance, housed thousands of students and teachers, and its library was one of the largest in the ancient world. These universities played a crucial role in the dissemination of knowledge and culture across Asia.
