Europa Universalis 4: Map and provinces

These commands change the map and its provinces. The fog of war and terra incognita commands make the whole world visible. Debug mode shows a province's ID and its owner's tag when you move the mouse over it, so you need to turn it on first for the commands that ask for an ID. The assimilate command makes a province entirely yours in a single line, together with its culture and religion.

Map and provinces: Common questions

How do I find a province ID?
Type debug_mode in the console to turn on debug mode. When you move the mouse over a province, its ID and its owner's country tag appear.
Are fog of war and terra incognita the same thing?
No. Fog of war hides armies outside your line of sight, and the fow command removes it. Terra incognita covers the regions you have never explored, and the ti command reveals them.
What is the difference between adding a core and taking a province?
If you type add_core in the console, the province becomes your core territory, and if you type own, you become the province's owner. If you want both, the assimilate command changes ownership, core, culture and religion at once.
Does the colonize command work in every province?
The command is meant for uncolonized provinces. According to the Paradox wiki, it colonizes the province, adds a core and gives you some prestige.
