The Mughal empire was a vast one. It included almost all parts of the northern India and half of south India. It consists of the people of all regions and faiths. Mughals believed that by having friendly relations with the native kings of all faiths and with the co-operation of the people of all religions they could rule their vast country for a long period. The idea of Sulh-i-kul or universal peace did not discriminate among people of different religions in their kingdom. So the policy of Sulh-i-kul (universal peace) would make the people of all religions and faiths co-operate with the emperor, and thus they could rule their kingdom with ease and comfort.
