What was sulh-i-kul?

Answer 1

Oh, dude, like, sulh-i-kul was this thing in the Mughal Empire where they were all about that religious tolerance vibe. It was basically a policy of universal peace and acceptance of all religions. So, yeah, it was like their way of saying, "Hey, let's all just chill and coexist, man."

Answer 2

"Suhl-i-kul" literally means "peace with all" in Persian. The term is associated with the Mughal Emperor Akbar the Great, who integrated many Hindus into high positions in his Empire and removed many of the civil disibilities to which Hindus had been subject in his empire. He also encouraged and participated in debates between authorities of various religious traditions, and started his own synchretic religious cult.
