If another great power has sphered a nation you will need 100 points and friendly status to remove the nation from sphere. 100 additional influence is needed to add the country to the Great Power's Sphere when said nation has a friendly status.ĥ0 influence can also be used to decrease the relation of another great power. 50 points is needed to increase Opinion up until 'friendly'. Great Powers may influence other countries to join their Sphere, which makes forming alliances much easier. It is important to note that tariffs will not apply to goods purchased on this 'common market'. This can be beneficial to ensure resource availability, as well as a captive market for finished goods. In Victoria 2, members of a sphere form a common market, on which goods are purchased and sold first, before going to the world market. A good example from this time period would be the Slavic states of the Balkans, which generally fell into Russia's 'sphere'. Think of a 'sphere' as a group of client-nations that are dependent on the sphere leader for guidance. If you have checked the level of influence of all 8 great powers, the allies of all the great powers that can possibly intervene, and the allies of nation you are attacking, you should know exactly who you are going to war with. This is not clear when looking at the 'declare war' window.ģ) A much larger nation becomes war leader after joining for either reason one or two, and they call in their allies. That is stated clearly in the 'declare war' window.Ģ) A great power has at least a 'friendly status' and chooses to intervene in the war. If you are attacking another nation, there are 3 scenarios where another nation can join the war on the opposing side:ġ) They are allied to nation you are attacking. Often you will just get sphered by a nation, that will turn out to be your main protection. When considering if they want to join a war or not, the AI have a 'political considerations' modifier which will be positive, if they also have an interest in attacking that specific nation.įor small nations, there is however often not a choice in who should be your great power ally. allying France as Russia if you intend on attacking Prussia. Last but not least it is better to choose someone, who naturally has the same enemy as you. Ottoman Empire might be the strongest ally you can get, but will be attacked so much, that it is just not worth it to risk the prestige hit by not honoring a call to arms. It is also better to choose someone, who does not have a lot of natural enemies. Austria might be a better ally than United Kingdom for a central European country, even though Britain technically is stronger.

Therefore, it is better to ally someone, who has direct land access to you. In general, the AI is very bad at transporting troops across bodies of water. As a general rule, the stronger an ally you can get, the better.
