Dlc icon legacy of rome.pngLegacy of Rome (LoR) is the second major DLC for Crusader Kings II, released in October 16, 2012, alongside patch 1.07.

It focuses on the Byzantine Empire (the Greek continuation of the Roman Empire) and the Orthodox Church.

Main features

If you don't own the DLC, the AI will not use the things it adds. In multiplayer, the host will decide what DLC are used, and is the only one who has to own the DLC. Minor DLC like gfx and music are decided by each individual player.

  • Orthodox councillors models
  • Byzantium Comes Alive: New sets of decisions and events specifically designed with the Byzantine Empire in mind, like being able to blind and castrate your prisoners.
  • Ability to restore the Roman Empire and/or mend the great schism via decisions.


Main article: Retinues

Retinues are your household guard; your elite core of professional soldiers. At the start of the game, most rulers are not able to employ Retinues, but it becomes possible as their total manpower (based on all the levies in their realm) and average Military Organization (a new technology) level increase. Over time, the Retinues turn into proper standing armies. The downside is that, as your Retinue capacity increases, your normal levies decrease in size. However, even at max tech, levies will still account for the majority of your armies.

There are many types of Retinues available for hire - including several unique cultural variants - though they always come in 500-man regiments with a commander of your own culture. Retinues reinforce in the field, like mercenaries, and when you first hire them, they start with 1 man. Unlike armies in other games, for example Europa Universalis, Retinues only cost maintenance while they reinforce. You are of course allowed to declare war even if you have Retinues.

Patch 1.07

Main article: Patch 1.07

Everything below comes with the free patch:

  • Improve your ruler: You can now actively strive to improve your skills or traits through the new Self-Improvement Ambitions
  • Appoint Orthodox Patriarchs: Orthodox kingdoms and empires can now control their own heads of religion and their powers, instead of being dependent on the patriarch of Constantinople
  • Have both a Plot and an Ambition at the same time
  • Leader Focus on Combat: Appoint your generals wisely, their traits and skills are now of vital importance on the field of battle. More commander traits are now added to increase the importance of your choice of military leaders
  • More Cultural Buildings
  • More unit-specific buildings
  • Improved AI
  • Bug fixes


Main article: Factions

New faction system: Join a royal faction and use your allies in the party to enhance your strength and tear down rivals. Experience Factional Revolts: No more easily defeated rebellions. Disgruntled vassals will now band together in revolt against your rule through their faction. Replaces many existing plots and normal revolt mechanics with factions.

Factions are, essentially, a kind of plot; a Faction has a leader, a number of members, and a clear goal (for example, to Lower Crown Authority in the Kingdom of England). However, there are some key differences: Factions always target the liege, and they are always known to the liege as well as the other vassals. A vassal can lead up to two Factions, but be a member in any number of other factions, unless their goals are contradictory. If a faction leader dies, the most powerful remaining faction member automatically takes over as leader. When the leader thinks the Faction is powerful enough, he can issue an ultimatum to his liege. The liege can then either give in to the demands peacefully or refuse, which triggers a Civil War where all faction members revolt together in an alliance.

Factions can be suppressed by imprisoning or killing the members, or simply making them like you, or by sending your spymaster to the faction leader in an attempt to make him end the faction. Being a member of a faction is risky as your liege will not like it. You also have no control over when a potential revolt starts, so you might find yourself at war with your liege at an inopportune time.


  • Succession by Primogeniture in [Title] (used to be a Plot)
  • Succession by Seniority in [Title] (used to be a Plot)
  • Succession by Gavelkind in [Title] (used to be a Plot)
  • Elective Monarchy in [Title] (used to be a Plot)
  • Lower Crown Authority in [Title] (used to be a Plot)
  • Independence
  • Install [Claimant] in [Title]

Liege Levies

In patch v1.07, you raise fewer, larger levies from your direct vassals. These levies are now handled separately from actual holding levies; you only get regular holding levies from your own demesne. The opinions of vassals of vassals are thus now mostly irrelevant; you only need to worry about the opinions of your direct vassals. Another benefit is that you don't get tiny little armies all over the place when you mobilize your realm. Liege levies also fix a fundamental balancing flaw in that you can no longer just keep raising little levies from all vassals as a war drags on (due to the portion of holding levies that was reserved for the liege). The new Liege Levies do not reinforce at home while raised.

Leadership Traits

Further leadership traits, like were added in patch 1.06 will be added:

  • Flat terrain leader
  • Rough terrain leader
  • Mountain terrain leader
  • Desert terrain leader
  • Holy warrior
  • Unyielding leader
