Akbar's concept of Sulh-i-kul (or Qul) means harmony and peace to all. Sulh-i kul is an Arabic term literally meaning “peace with all,” “universal peace,” or “absolute peace,” drawn from a Sufi mystic principle. As applied by the third Mughal Emperor of India, Akbar (who reigned 1556-1605), it described a peaceful and harmonious relationship among different religions.
