Your challenge is to get an official Catholic, Orthodox and Muslim triple alliance (or rather a triple alliance among the subsequent kings of said faiths in an around the middle east and Europe) to form with the purpose defending the shared holy land from the Mongols in the 13th century.
Said alliance does not have to successfully campaign against the Mongols but bonus points if you get it too.
Depending on your answer what are the long term effects?
