De jure empires in 1066.

Empire.png Empires are the highest level of landed titles in CKII, above kingdoms. The portraits of emperors Emperor.png have gold borders with purple trim.

Empires are very large and difficult to form. However, their ability to employ kings as vassals makes management of large realms considerably easier. In the start date 1066, only the Holy Roman Empire and Byzantine Empire already exist. In 867, the Arabian Empire is under the control of the collapsing Abbasids, however the Holy Roman Empire does not exist, but may be formed by decision. In 769, the Abbasids have only recently taken power and are on the ascent; the Holy Roman Empire can likewise be formed by decision. The Mongol Hordes begin appearing after 1216.

There are two additional mechanics available to Emperors not afforded to lower-tier rulers, tied to the Legalism technology: Imperial Administration, which grants free revocation of Duchy-level titles and a substantial increase to vassal limit, and, with the Charlemagne DLC, Viceroyalties, which are lifetime-only title grants that return to the emperor upon death. Both are demesne laws, with the Administration law being either Feudal or Imperial, and Viceroyalties allowing none, kingdoms, or both duchies and kingdoms. The Byzantine Empire begins with both Imperial Administration and Duchy-level viceroyalties.

To create or usurp an empire, you need:

  • to control at least 80% of its de jure land.
  • to hold either two kingdom titles, or an empire-level title.
  • to meet specific religious and/or cultural conditions (since patch 2.0 most conditions only apply to the AI).

Custom Empires[edit]

With the Charlemagne DLC, rulers can create a custom de jure empire. This decision is available to independent kings with 8000 prestige as well as either 180 holdings in their realms, or else 3 kingdom titles. Custom empires are named after, and take the color of, their creator's primary kingdom (although they can be renamed with the customizer DLC). When formed, all kingdoms either held or entirely controlled by their creator become de jure vassals of the new empire.
