Heritages are a set of modifiers assigned to each state, usually consisting of two bonuses and one malus usually reflecting its culture, history, or ambitions. Several countries have unique heritages, while the remainder share group heritages. Heritages are pre-assigned and cannot be changed over the course of a game, not even when creating a formable nation, outside of a few rare events.

Our people prides itself with its great skill as riders and its horsemanship. Nobles and commoners alike learn to ride at an early age and as a consequence the force of our cavalry arm can make the strongest of empires tremble. A pastoral lifestyle has made many accustomed to a free way of life however, fostering an autonomous mode of government where chieftains and nobles have great say over their own business.
