Which mughal ruler tried to use urdu as state language?

While Akbar is often credited with promoting Urdu, he did not try to make it the state language. It's important to remember that:

* Persian remained the official language of the Mughal Empire throughout its history.

* Akbar's efforts were more focused on fostering a sense of cultural unity and promoting a more inclusive society.

* He encouraged the use of Urdu in court, literature, and music, but never attempted to replace Persian as the official language.

While Urdu's roots lie in the Mughal era and its development was certainly influenced by Akbar's patronage, it was not until the British colonial period that Urdu truly emerged as a major language in South Asia.
