Amir Khusro lived during the Delhi Sultanate and served in the courts of multiple rulers, but his most influential and well-known association was with Alauddin Khalji. Under Alauddin’s patronage, Khusro composed poetry, historical works and devotional literature in Persian and Hindavi. He contributed to music by developing new ragas and inventing instruments like the sitar (according to tradition). His works celebrated cultural fusion and greatly influenced Indian literature and music. His close relationship with Alauddin allowed him creative freedom and recognition, making that period the most productive phase of his life.
