32.3 ALLIANCES
...
C. Dynastic Ties
A pair of players may conclude a marriage between the ruling families of their realms, so as to create family ties. They can no longer declare war on each other without Casus Belli (CB). This allienace last for the whole duration of the next 2 consecutive turns [of 5 years each], except when specific events occurs, forcing its cancellation.
C.1 To conclude this marriage, one of the two players has to offer a dowry to the other.
C.1.1 The dowry has to be 100 ducats (minimum, more can be offered), or consist of one single province, Colony or Trading-post, immediately ceded to the other, receiving, party upon conclusion of the agreement (i.e. at the end of the Diplomatic Phase).
C.1.1 The ceded province, Colony or Trading-post must be 100% under the control of the ceding player, ie.e it is not possible to cede any territory in revolt or occupied by another player at the time of the dynastic treaty.
C.2 The two players are authorized in addition to exchange an extra province, Colony or Trading-post.
C.2.1 This exchange may be made in addition to the dowry (e.g. exhange of one province + dowry of a province / or 100+ ducats), but it is not compulsory and may never involve national provinces.
C.2.2 This extra transfer costs 1 level of Stability to the ceding party.
C.3 The dynastic alliance can be canceled at any time. The party that cancels it loses 2 Stability levels.
C.4 Only the dynastic alliance allows players to cede or exchange a province, Colony or Trading-post. Each ceded possession has to be specified at the time of the alliance conclusion.
C.4.1 Each ceding costs 1 level of Stability to the ceding party.
C.5 The player that pays the dowry can benefit from a War of Succession inside the other player's country, i.e. he is allowed to declare war on that country as if he had a CB, or on the contrary he is allowed to enter a war as a ally of that same country (See 53.35), as if he had a defensive alliance with it.
C.5.1 This is valid only if a dynastic Crisis occurred in the country that received the dowry.
C.6 A dynastic alliance cannot be renewed with the same player less than 3 complete turns after the official end (i.e. be it after two turns of earlier because it was previously broken) of the previous alliance.
C.7 A dynastic alliance cannot be formed with a player of a different religion unless a 2 Stability levels loss is incurred for doing so.
C.7.1 This applies until 1615 between Protestant and Catholic countries and until 1665 between Catholic / Protestant and Orthodox Christians countries. It always applies between all Christians and Muslims.
C.8 Historical Option (not recommended for play balance): A dynastic alliance can never be formed by Turkey with any other player.
