WI the Christian community which eventually coalesced in the Kerala region of India in about 800AD formed into a proper, and long lasting state?
How would this largely Christian state fare with the Muslim invasions? These predominantly came from the northwest, so would be familiar with Byzantium and the Crusader states, so would this lead to attempts at jihad against the Indian Christians?
Kerala is at the north end of the monsoon trade routes, so would it have regular contact with Axum/Ethiopia, the Christian state which would be the easiest to travel to?
