Trade leagues

Merchant republics lead a trade league based in their center of trade (COT). By joining a trade league, a state agrees for its provinces to trade only from the leader’s COT. In exchange, league members can trade at both the league and foreign COTs using the merchant republic’s competition modifiers rather than their own. Additionally, trade league members will randomly get the event - Trade station founded in their provinces. Leaving a trade league will remove all trade stations on the 1st of the next month unless the state joins another trade league.

At the game start in 1399, most of the eastern Mediterranean is in the Venetian league while the Genoese league covers the western Mediterranean. Northern Germany, Scandinavia, and England are members of the Hanseatic League. Novgorod’s league, due to general enmity between Russian states, tends to be far smaller.

Trade league war

If a league member leaves the trade league, the league leader gets the Trade league war casus belli on the departing member. The league leader can force the opponent to rejoin the trade league, pay an indemnity or concede defeat. The casus belli has a duration of 12 months.

Trade rights

Merchant republics can also gain trade rights for specific resources. This diplomatic option ensures that all provinces producing a certain trade good from one state will trade in the merchant republic’s COT. Provinces producing the resource get a 66% bonus to local production while the trade value of the province is reduced by 25%. Therefore, merchant republics should not obtain trading rights from league members or any state already trading in its COT.

Form of government change

If a merchant republic owns no province with a center of trade its government is changed to administrative republic by the event: ‘Center of trade lost’.

A merchant republic may change with loss of stability to the following forms of government:
