Which Mughal ruler patronaged Kavindra Acharya Saraswati of Banaras, a great scholar of Sanskrit and Hindi ?

Shah Jahan (reigned 1628–1658) was the Mughal emperor who patronized Kavindra Acharya Saraswati, a renowned Sanskrit and Hindi scholar from Banaras. Kavindra Acharya is most famous for leading a delegation of scholars to the Mughal court to successfully plead for the abolition of the pilgrimage tax (Ziyarat) imposed on Hindus at holy sites like Kashi (Banaras) and Prayag (Allahabad). Impressed by his profound scholarship and eloquence, Shah Jahan conferred upon him the title "Sarvavidyanidha" (Ocean of all knowledge). Kavindra Acharya authored the Kavindra-Kalpadruma, which includes panegyrics in honor of the Emperor. While other Mughal rulers like Akbar and Jahangir were also known for their patronage of arts and literature, the specific historical intervention regarding the pilgrimage tax and the scholarship of Kavindra Acharya are distinct highlights of Shah Jahan's reign.
