Integrated cultures do not assimilate, count towards the number of pops for research speed, are allowed to colonize, and generally have the highest happiness of all cultures. Integrated cultures Ĭultures with citizen or noble civic rights are considered an integrated culture, forming an integral part of the court, administration, and military with the highest level of cultural privileges. However, it is possible to unlock other tradition trees by integrating their cultures and adopting the appropriate traditions. The subject types available also depend on primary culture another state can only be made a feudatory if it is in the same culture group as its new overlord, and satrapies can only be made of states with Persian military traditions, which consist generally of countries in the Iranian, Caucasian, Anatolian, Scythian, Bactrian, and Aramaic culture groups.Ī country's starting military tradition trees is also determined based on its primary culture/culture group, which affects what military and economic bonuses can be accrued by spending military experience, at least initially. States of a different culture (in the same culture group) get a -10 opinion malus, while those in a different culture group get a -20 opinion malus. The primary culture also has an effect on diplomacy. As an alternative to assimilation, cultures can be integrated to be given the same rights as the primary culture, at the expense of the happiness of already integrated cultures. Outside of events pops will always assimilate and convert to the primary culture. Assimilation is also slowed if the dominant province culture and/or religion is not the same as that of the state, all of which makes the conquest of wrong culture (especially wrong culture group) and wrong religion areas significantly more difficult, especially in the early game. Most often the culture of the state population is more diverse, but pop culture can be gradually changed to match that of the state during the playthrough via assimilation, as pops of a different culture and especially culture group have a significant happiness malus that can become very difficult to manage if stability begins to drop.

Pops of the primary culture are typically the happiest and most satisfied pops in the realm, and are fixed to the noble civic right. Outside of a few specific events, decisions, and mission tasks, such as the startup events for Heraclea Pontica, the 20px Parthia formation decision, the final tasks of the Hellenistic Empire mission tree, and events during the Yuezhi migrations, the primary culture generally cannot be changed except for during a barbarian takeover. Every country begins the game with a predefined primary culture, which can be seen at the top right corner of the Diplomacy screen.
