Does ship trade power affect privateering eu4? In order to move your capital to the new world, your capital has to be the last stated province on that continent, and your target continent has to have >50% of your total development. The new capital must have at least the same amount of development of the current capital or the cost will be higher than the minimum.
The capital can be moved to any province on which the country has a core and is inside a state, though the province itself need only have a territorial core. If your home trade node hasn’t been moved before, moving your capital will also move your home trade node along with it.
This is most useful during early conquests as small nations. Moving capital to a high dev province with high autonomy for the sake of reducing autonomy down to 0. Say i control 70% of node A but only ~5-10% of all of the nodes which feed into it (Venice might be a good example of this). Transferring trade power is a way of pushing trade to nodes in which you have more power (and thus can collect more).
