In this study, the activities of the sultans who reigned between the years 1526-1707 in the Mughal Empire founded by the Turks in the Indian Peninsula were examined. By mentioning the intellectual structures of the sultans, what kind of contributions they have made in the creation and development of libraries are discussed. It has been observed that activities related to librarianship such as enrichment of libraries with the translation of old works, the increasing visibility in books together with embroidery and long-term preservation of books thanks to bookbinding were prioritised. It is also worth noting that the palace library was developed by moving the libraries in the conquered places to the centre. It was also revealed that the palace library, whose foundations were laid with Babur Shah and Hümayun, systematized with Akbar Shah, developed with Jahangir, Shah Jahan and Aurangzeb, was a library with a unique richness.
