===Provinces===
What your nation is made of. Provinces are your territory and as such provide the basis for your nation. The most important factors of a province are the level of its development, buildings and if its a core province or not. When you annex new provinces from an opposing nation, usually through a war, they start out as territories, meaning that they are merely de jure part of your Nation and your administration doesn't actually cover it yet. You spend administration points to core provinces you aquired in a war; if you gain provinces through colonization, annexing vassals, junior partners or inheriting them, this isn't necessesary. Every province has a trade good assigned to it, representing its primary export, and trade goods have a value assigned to them that changes over the course of a game.
