Which belief system gained prominence in India during the Mauryan empire?

During the Mauryan Empire, Buddhism gained significant prominence, particularly under the reign of Emperor Ashoka. After his conversion to Buddhism following the Kalinga War, Ashoka promoted its teachings and principles throughout his empire, establishing stupas and edicts that emphasized non-violence and moral living. This support helped Buddhism spread widely across India and beyond, influencing various aspects of culture, art, and governance. Additionally, Hinduism continued to thrive during this period, but Buddhism's rise was particularly notable.
