Suleh-e-kul, a doctrine of universal peace and tolerance, was promulgated by Emperor Akbar to unite India’s diverse populace. Emphasizing equal respect for all religions, this policy aimed to counteract the divisive tendencies inherent in a multi-ethnic, multi-religious society. By fostering a national identity that transcended religious boundaries, Akbar sought to build a cohesive empire where communal harmony was paramount. Today, Suleh-e-kul remains pertinent as India grapples with issues of secularism and communalism. Its principles could guide contemporary policies to ensure that India’s rich diversity is seen not as a challenge but as a strength, promoting unity and social cohesion.
