Goswami Tulsidas
Tulsidas, a Brahmin whose original name was Ram Bola Dubey. He composed the Ramcharitmanas on the bank of the Ganga in Varanasi - he is said to have begun writing on Ram Navami day in 1574 and completed the poem over the next few years. He lived in the time of Emperor Akbar, and some believe that he was in touch with Abdurrahim Khan- e-Khanan, the son of Akbar's commander Bairam Khan, and they possibly exchanged some poetic communication as well. Besides Ramcharitmanas, Ramlalla Nahachhu, Barvai Ramayan, Ramagya Prashna, Parvati Mangal, and Janaki Mangal in the Awadhi language are some of Tulsidas' popular works.
