Religion (M2TW)

In Medieval 2: Total War there are five different religions, namely Catholic and Orthodox Christianity, Islam, Paganism and Heretic.

Religions

Christianity

Christian Factions can be either Catholic or Orthodox Christians. Catholic factions receive missions from the Pope, while Orthodox factions do not.

Pope

The Pope is the head of the Catholic Church, and is the head of the Papal States Faction. The Pope can excommunicate a faction if their relations with him drop too low. Excommunication causes religious unrest within the affected faction and also means a Crusade can be called against a Catholic faction.

College of Cardinals

The College of Cardinals is an organization of catholic priests that is centered in Rome. It is formed of the most pious priests in Christendom, and any sufficiently religious priest can be selected for it, if one of the thirteen seats is open. Contrawise, if there are no priests of high enough Piety(5) then no more seats in the College of Cardinals will be filled until this criterion is met. Cardinals usually remain under their faction's control, simply gaining an extra piety point from the "Cardinal" trait. However, whenever the Pope dies, an election is held among the College to determine the next pope.

Crusades

To start a crusade you must go to the pope overview scroll, which is a tab within the faction information menu (Press your faction shield in the campaign map UI, at the bottom right(ish) of the screen). From the pope overview scroll request the pope to call a crusade via the "request crusade" button, depending on the pope's relationship level with your faction, you may or may not have to pay an amount of money. Once the crusade has been called you must then join the crusade, or suffer lower relations with the Pope (see below).

Once the Pope has called for a crusade, whether it was requested by your faction or another faction, you are able to join it. To join the crusade you must have an army with more than 8 units in it. Once you do, select that army, and press the "Join Crusade" button. You can have more than one crusading army at a time. Regardless, all armies that you have selected to join the crusade will now become a crusading army, which has free upkeep for all units and is able to move twice as far as normal (even when being transported by ships). Furthermore, you are now able to recruit crusader mercenaries, such as crusader sargents, turkupole horse archers, and grand crosses which inspire your men and swell its ranks. However, units can only leave the crusading army if it captures a settlement, and if the crusade doesn't move fast enough men, will begin to seek a new lord who will finish the crusade (i.e, desertion).

Crusades give bonuses in terms of experience for all units involved, as well as chivalrous traits for any generals who lead crusading armies, even if their army doesn't take the crusade objective (except if they abandon the crusade of course). Furthermore, joining crusades allow guilds of crusading orders of knights to be built.

Islam

The Islamic factions that start the game are the Moors, Turks and Egyptians. (Mongols are in vanilla version) All Islamic factions can call jihads.

Jihads

In order to request a Jihad, the player must click on an Imam and look for the Call Jihad button. The Imam has to have a piety of at least 4 to request a Jihad. However, they cannot be called in quick succession. Jihads have the same problems and benefits of a crusade.

Pagan

The Aztec Empire is the only genuinely Pagan faction in the vanilla version. However, several rebel regions - such as Stettin - start out pagan and must be converted.

Heretic

The rebel faction is the only faction which belongs to the Heretic religion.

Religious Agents

Religious Agents appear on the campaign map and have a primarily religious affect.

Priests and Imams

Priests and Imams are essentially the same type of agent, Priests being the Christian version, and Imams the Islamic version. They are recruited from settlements that have their corresponding religious buildings, and when left in a region, they will convert the people of that region to their religion, based on the rate of how much religious skill they possess.

Heretics

Heretics are campaign map characters that increase the level of Heresy in the regions they pass through. They are effectively Priests for the Rebels faction.

They may be denounced (in other words, burned at the stake) by a Priest or Imam that bears a high enough religious skill.

Witches

Witches are similar to Heretics in that they spread Heresy. The only notable difference is that they are female.

They may be denounced (killed) by a Priest or Imam with a high enough religious skill.

Inquisitors

Inquisitors are rather troublesome campaign map characters who are sent by the Pope to 'deal with Heresy' in your region.

Keep in mind that 'dealing with Heresy' can result in the trial and execution of some of your best agents, whether they be generals, merchants, diplomats, or family members!

Inquisitors, like any other campaign map character, can be assassinated.
