Europa Universalis: Der Preis der Macht

You cannot legally declare war without a valid casus belli; the types of CBs and the timing/requirements for declaring war are explained in the declaration-of-war section (see page 22).

No — occupation influences peace negotiations but annexation is a specific peace term that must be eligible and enforced during peace resolution rather than being automatic (see pages 29–31).

Armies must use naval transport and appropriate fleets/ports to cross sea zones; embarkation, naval movement and transport rules (including port requirements) are covered under naval transport and movement (see page 26).

Rebels spawn, move and conduct sieges during the Rebel/Peace phase (Phase 3) and follow the rebel movement, siege and occupation rules explained there and in the Rebels section (see pages 9 and 37).

Leader/advisor deaths remove their effects and can cause wounds or interregnum consequences; monarch power, leader limits and the effects on stability and actions are detailed in the Monarch Power and leaders sections (see pages 19–20 and stability effects on page 10).

Calls to Arms and alliance response rules specify when you must join an ally’s war and what restrictions or Active Ally abilities apply; the full CtA/Alliance and Active Ally mechanics are described on pages 32–33.
