Trade Routes

Trade Routes are manually set up on game start based on their Region and Religion, according to the historical flow of goods.

These initial Routes are Dynamically redefined whenever the current holder’s Religion_valentinianism Faith orRealm_capital-provinceCapital Province Region changes.

While Regions define the likelihood of a good reaching a certain point, pdx-Faith Religion is the most important delimiting factor for trade contacts to happen.

1. trade-region Trade Regions

Dynamic Trade Routes defines different trade-regionTrade Regions for all duchies, mainly as subsets of pdx-Titles Regions defined in Vanilla (see image above). Some pdx-Duchy duchies are also relocated, such as:

  • pdx-KingdomFlanders belongs to the trade-region Northern France trade region and not to pdx-Titles Germania.
  • pdx-KingdomBrittany belongs to the trade-region Celtic trade region—including Goidelic- and Brythonic-speaking areas—instead of pdx-Titles Francia.
  • pdx-DuchyPomerania belongs to the trade-region Baltic trade region rather than to pdx-Titles Germania.
  • pdx-DuchyCatalonia belongs to the trade-regionSouthern France trade region instead of pdx-Titles Iberia.

Region Modifiers

Each Productive Barony exports a percentage of its Production to other Regions, based on its defined Trade Region. These are the modifiers:

  1. Main Subregion: 80%. Within the traditional realm or very close ties.
  2. Main Region: 60%. Close geographical or historical (trade, diplomatic) ties.
  3. Neighbor Region: 30%. Relatively important (direct or indirect) geographical or historical contacts.
  4. Distant Region: 10%. Indirect geographical or historical contacts.
  5. Other Regions: 1%. Level “Hey I found this rare good”.

If the holder of a productive barony has itsRealm_capital-province Capital Province in a different Trade Region than the one initially defined for it, that region will also be considered Main Subregion for the purposes of trade.

2. pdx-Faith Trade Religions

During the Middle Ages, usual trade happened between regions under rulers of the same religion, and inter-religious interactions—while possible—were rare. Common examples of inter-religious contacts are networks set up by pdx-Religion_kabarism Jewish communities or by feudal_government Republics in the Mediterranean.

Dynamic Trade Routes defines a set of common relationships between different pdx-Faith Religions or Religion_valentinianism Faiths.

Religion Modifiers

Each Productive Barony exports a percentage of its Production to other religious groups based on its defined Trade Religion. These are the modifiers:

  1. Main Faith: 100%. Own Faith or Religion
  2. Main Religion: 75%. Traditionally associated Faith or Religion in the Region.
  3. Neighbor Religion: 50%. Traditionally not hostile Faith or Religion, or with active trading partners, in the Region.
  4. Distant Religion: 10%. Other close Faiths or Religions which could occasionally be trading partners in the Region.
  5. Other Religions: 1%.

A change in pdx-Faith Religion by the holder of a Productive Barony will have a variable effect, depending on the predefined religious change:

  • pdx-Religion_orthodoxOrthodox topdx-Religion_catholicismCatholic or vice versa:
    • The new faith becomes Main Faith, the older faith becomes Main Religion.
    • All other Trade Religions remain the same.
  • Change among the main Indian Religions – pdx-Religion_shaivismHinduism,pdx-Religion_lamaism_buddhismBuddhism,pdx-Religion_jainismJainism – will not result in any change.
  • Every other change will mean the new holder’s pdx-Faith Religion (orReligion_valentinianismFaith, in the case ofpdx-Religion_orthodoxOrthodox vs.pdx-Religion_catholicismCatholic vs.pdx-Religion_adamitesOther Christians) will become the Main Faith, whereas all other defined Trade Religions will lose one level of export: from Main Faith to Main Religion, from Main Religion to Neighbor Religion, etc.).
