Ideologies are a new end-game concept introduced in the Civilization V: Brave New World expansion pack. Ideologies take your society to the next level of social development, when tradition and custom cease to be the means for some additional bonuses for the empire and instead become a kind of a philosophical system which not only organizes your empire's view of the world, but is also able to affect the hearts and minds of common people in other nations. The three Ideologies available were formerly the Industrial Era Social Policies, which have now been expanded with additional content and more interesting gameplay mechanics in order to provide another level of depth in the late game.
Ideologies can be conceptualized as large, mutually exclusive social policy trees which affect not only one's own civilization, but also exert pressure on other civilizations. Besides bonuses provided, there are also diplomatic repercussions, especially when empires don't share an Ideology. Happiness can be strongly affected by ideological interaction, and in fact hamper a nation's development.
Every civilization has to choose an Ideology when reaching the Modern Era, or after finishing three Factories (annexing or puppeting cities with their Factories intact counts as well). The choices are:
When prompted to choose, you can see the recommended Victory types per each Ideology; furthermore you can see all its tenets when you click on its details. Choose very carefully - the Ideology will channel the rest of the game for you!
By choosing an Ideology, you choose a path for the continued social development of your civilization. You can then focus on that path by adopting tenets for the chosen Ideology. These are basically theme-based social policies, and provide different bonuses for the empire. The way you adopt tenets shapes your Ideology, and tailors it to your needs and goals. See below for more information.
Ideology has a big impact on the diplomatic relations with other civilizations, both in standard negotiations and in the matters of the World Congress. One very obvious effect is that you can have an idea of a civilization's voting intentions in the Congress if you follow the same Ideology even if you have no Diplomat in their capital! But other than that, those that follow the same Ideology as yours will tend to be more friendly to you, supportive, and open to sharing information. On the other hand, those with different Ideologies will tend to become more hostile. Another effect for differing Ideologies is a penalty on your Tourism influence to other civilizations (which will make it harder to progress towards a cultural victory).
Public Opinion and Preferred IdeologyEdit
The new cultural concept which involves a civilization gaining influence over other civilizations with Tourism also plays a major role in Ideologies. As in real life, travelers and tourists spread not only the culture of their nation, but also its political ideas, so the Tourism generated by a civilization also creates ideological pressure on other civilizations. In other words, politics now becomes a major factor in a nation's life, with the potential power to cause serious harm.
The main effect which expresses this is Public Opinion. Public Opinion refers to how well the people of one civilization feel about the Ideology their leaders have chosen. As such, there is no Public Opinion present with civilizations that have not adopted an Ideology yet.
A civilization that is not being influenced at all, or otherwise being influenced only by civilizations sharing the Ideology, will have the default Public Opinion level of Content (The people are in full agreement with their leaders about the ideology they are following). Conversely, when a civilization is being influenced by another one with different Ideology, its Public Opinion will drop to the lower levels, based on the exact influence difference:
- Dissidents: Some enlightened people feel that there is something wrong with their ideology, and spread some discontent among the population, usually limited to media articles or graffiti.
- Civil Resistance: The people unhappy with the nation's Ideology become many and organize to start causing mayhem. Strikes, protests and sporadic violence may be seen as a result.
- Revolutionary Wave: This is the lowest level of Public Opinion. There is widespread discontent with the Ideology among the population and conscious efforts to effect a change are being constantly made. A Revolution is near!
To determine this, the civilization's total Tourism output is compared to the others' Tourism - if the incoming influence is larger than the outgoing influence, Public Opinion drops. The larger the difference, the more severe the drop. If the Ideology of the nation influencing yours is the same as yours, then Public Opinion will stay Content (because their ideas are basically the same as your ideas). Public Opinion only drops if the nation influencing you has a different Ideology.
The effect of low Public Opinion is the reduction of Happiness. Discontent from Public Opinion translates directly into a certain level of added Unhappiness for your empire (depending on the number of Cities, or the number of Population, whichever is greater). The Unhappiness penalty is more severe the higher the level of discontent is.
Based on the incoming cultural influences, the civilization will also have a Preferred Ideology. If the Public Opinion is Content, then the Preferred Ideology will always be the Ideology currently being followed. Otherwise, citizens will prefer the Ideology of whichever civilization(s) has the most influence over them. Depending on how severe the penalties are, a civilization may be compelled to change to the public's Preferred Ideology.
It is very difficult to maintain a Content Public Opinion level - you need to be a culturally strong civilization, be it in your Tourism stat or your total Culture generated, otherwise you will have to deal with some Unhappiness generated from Public Opinion. You can eliminate that by switching Ideology, but this cannot be done while the Public Opinion is Content (and of course, you have no reason to do it in this case). Making an Ideology the World Ideology will also remove the Public Opinion for civilizations following that Ideology, while at the same time applying an extra level of Public Opinion against civilizations of different Ideologies.
When the Public Opinion of an empire drops to the lower level of discontent (Civil Resistance or Revolutionary Wave), and their other sources of Happiness aren't enough to counter the negative effects, allowing the empire to reach low general levels of Unhappiness (in the range of -10 to -19), the first adverse effects will manifest themselves with the appearance of Rebel units in random locations near cities in your empire. Rebels will attack your empire randomly, like the Barbarians, but they won't behave exactly like them - don't be confused by their black and red colors! Note also that Rebels are at the same tech level your civilization currently is, which means that they're pretty dangerous!
But even more severe effects will happen when Unhappiness reaches levels as low as -20! At this point some cities within the empire will begin to revolt, meaning that they will leave the empire on their own. The city to revolt will usually be whichever city is closest to the Capital of a civilization following the Preferred Ideology, and it will defect to said civilization. Note that only cities will switch sides, along with the territory controlled by them - no units which happen to be in that territory will switch. All Great Works which happen to reside in a "rebel" city will also switch to the other civilization. The city will still have a period of resistance and need a Courthouse (or it can be razed or made a puppet).
Because of the severity of these revolts, the game will give you advance warnings about impeding city revolts. Pay attention and try to raise Happiness in time to prevent the defection, by whatever means necessary!
Finally, in order to satisfy the masses, the civilization undergoing revolution may be compelled to switch to the Preferred Ideology. This brings the Public Opinion back up to Content, and gets rid of Unhappiness originating from Public Opinion, but of course at the cost of the benefits from Tenets that had previously been adopted. Upon switching Ideologies, you get to pick a number of Tenets in your new Ideology equal to the number of Tenets you had in your old Ideology, minus any Early Adopter tenets you may have received from being one of the first two civilizations to pick that Ideology.
In this way, Ideologies and Tourism, combined with the World Congress's ability to further reduce Happiness and sap the opponents' abilities to fight back, can be used as an effective weapon to cripple opponents' empires and steal cities from them without having to deal with the monetary, production and diplomatic costs associated with going to war.
It is possible to change your Ideology, whether by choice or by necessity, but this is highly inadvisable. When you switch Ideology, your empire will have a one-turn Anarchy, which means that all your cities simply stop working for one turn - they not only stop their current Production, but they also don't produce any stats! Another bad, far more serious thing, is the fact that you lose access to all tenets you had adopted from your previous Ideology. And if you had adopted many, this can turn out to be a complete disaster, since you may depend on them to maintain Happiness or any other number of stats.
If the switch was a result of a social revolution, then you may not have much choice. At least, in this case you may end up actually recovering your empire's Happiness, thanks to Public Opinion being set back to Content and removing all resulting Unhappiness.
Still, it is highly advisable to avoid switching Ideology at all costs! So, think well when you choose your original Ideology!
Each Ideology has a set of 16 Tenets, divided into three levels, which represent the gameplay effects of the chosen Ideology. Ideological Tenets can be unlocked by accumulating Culture, the same way you adopt new Social Policies. When you have accumulated a sufficient amount of Culture, you are given the option to adopt a new Social Policy or a new Ideological Tenet.
However, Tenets aren't organised in such strict 'trees' as in Social Policies - they are divided into three levels, true, but all Tenets from the same level are interchangeable - that is, it doesn't matter which ones you will adopt first, as long as you have the necessary number to unlock a next-level Tenet.
You first unlock a Level 1 Tenet slot, which you can fill with any effect you choose from the list of Level 1 Tenets. Every Tenet after the first in the same level unlocks one new slot for a Tenet of the next level. You may choose which Tenet you want to unlock first within a level, much like you choose Beliefs when founding or enhancing a Religion. Note, however, that unlike Beliefs, different civilization may choose the same Tenet (which won't become unavailable after the first civilization chooses it, the way Beliefs are).
Each Level 3 Tenet in an Ideology is associated with one of the victory conditions recommended for the Ideology you're currently following, providing some sort of bonus for achieving it. One of these helps you achieve a cultural victory, while the other two give you an edge to achieve two out of the three other available victory conditions.
The first two civilizations to adopt a certain Ideology will receive a reward, respectively two and one Early Adopter free tenet(s), giving them an early advantage to improve their Ideologies and gameplay.

The three Ideologies can easily be connected to the three major ideological movements that gained momentum in the 20th century: Liberalism (Freedom), Communism (Order), and Fascism (Autocracy). The names of many Tenets (Five-Year Plan, Militarism, New Deal, etc.) also directly point to these connections. Of course, from a game standpoint, you can develop each Ideology in such a way that it does not resemble its real-world counterpart - the game gives you a lot of freedom in this matter.
Like Social Policies, Ideologies will grant a unique honorific title to the nation's leader:
- Freedom grants the title "President".
- Order grants the title "Chairman".
- Autocracy grants the title "The Terrible".
