Casus Belli

The Casus Belli is the justification for a war in Grosse Welt, as one is necessary for one nation to declare war on another nation. The concept is borrowed from the Paradox Interactive Game, Europa Universalis IV, but the 'War Goal' portion is thrown as away, as mechanics like War Score and Ticking War Score are thrown out the window in Grosse Welt, since it is a Nation Roleplay, not a Videogame.
