Medieval India (education): In whose reign was the Madrasa-i-Nasiri established to meet the educational needs of the people? Context: Delhi Sultanate administrative and cultural institutions. Choose the correct ruler.

Note on wording: The original prompt said 'region'; standard history references frame this as the ruler's reign. I interpret it as “in whose reign”.

Given data

• Institution: Madrasa-i-Nasiri.
• Era: Early Delhi Sultanate.

Concept/Approach
Identify the early Sultanate patron who encouraged learning and religious institutions.

Reasoning
Iltutmish (r. c. 1211–1236) consolidated the Sultanate and patronized educational/religious endowments; the Madrasa-i-Nasiri is associated with his reign.

Common pitfalls
Confusing Iltutmish's cultural patronage with Aibak's earlier foundational works or Balban's later administrative rigor.

Final Answer
Shams-ud-din Iltutmish
