As a Doge, you can ask a feudal lord to declare an embargo war on a rival republic for a suitable sum of money.
If successful, all their trade posts in your territory are destroyed, and you get a lot of money out of it (if they are infidels, you also get Piety.)
As a feudal lord, you can declare an Embargo War on a Republic. You can declare wars to simply seize a trade post, both from a rival Patrician and from another Republic. You can plot against rival Patricians to take over their trade post. There are several ways of taking over or destroying a Trade Post: So, what is the catch? Well, there can only be one Trade Post per county, setting the stage for an eventually bitter struggle for control over them, both between rival Republics and rival Patricians. The bigger the Trade Zone, the bigger the income bonus (with diminishing returns.) Trade posts can link together to form Trade Zones, which is simply an area (on land and sea) of connected Trade Posts. They also provide a modest income boost to all cities in the county. Most importantly though, they have a significant income, based on the total tax value of the county in which they are built.
They can be upgraded with buildings like normal Holdings.
Trade Posts have a fort level and a small garrison, but they do not provide a levy. Patricians can build a special type of holding called a Trade Post in any coastal county. Now, they are called Merchant Republics, so you would expect them to trade, and that is precisely what they do. I hope you've all had a merry Christmas! As promised, in this week's dev diary I'll talk about the differences in gameplay between normal feudal lords and Merchant Republic Patricians.
