Jihad (M2TW)

In Medieval 2: Total War, Jihads are the Islamic equivalent of Crusades. The main difference between a Jihad and a Crusade is that Jihads are not called by the Pope. Instead, every Islamic faction with an Islam who has a piety of at least 4 can call a Jihad. Once a Jihad has been called, all Islamic factions can decide to join it with one or multiple armies. Jihading armies have increased movement points but if they do not move closer to the Jihad's target every turn, the soldiers will begin deserting.
