Trade is a way nations can generate income and get access to goods they need.

Commerce

Income from Trade uses Commerce. Each Marketplace in a city provides +5% commerce Income to that city, and citizens will provide 0.01 Commerce Value Modified By citizen Output efficiency. Trade Income is based upon total amount of trade-routes in & out in province multiplied by commerce.

Trade Routes

A Trade Route is import of one trade goods from another province, either foreign or within the nation, where it is in surplus, to one of the nation's provinces.

A nation can always import any trade goods it has a surplus of from its other provinces, but from foreign nations it needs to have negotiated trade access first.

If two trading nations fight a war against each other, all imports between them are cancelled.

A province can only export if that province provides a surplus, ie, if it in total produces more than 1 of that trade-goods. A city produces 1 trade-goods, and for each additional 15 slaves it produces an additional +1 trade goods. There is no limit to how how many exports a province has, other than the amount of surplus goods it has.

A nation can always import a trade-goods if it already has a surplus of it, and that gives you a smaller additional bonus.

Surplus in the capital province gives a special bonus on the country level and Surplus is indicated in the UI.

Only the capital city in each province gets the benefit of the stacked goods. The other provinces gets counted as they have access to 1 of the trade-goods. Only the province stacking bonus can be applied multiple times.

Creating a new import route costs civic power. As default a nation can import one trade good to its capital province.

Increasing Import routes

A nation has multiple ways to get more allowed import routes to its provinces:

  • the starting trade route cap is 3
  • Larger nations get more import routes to their capitals,
  • There are ideas that allow more import,
  • There are inventions that can either increase all provinces trade routes or the capitals.
  • There are also economic policies for trade, where a nation can forgo its income from trade for having more trade routes, or the opposite.
  • Must be in diplomatic range to trade.
