A mod (short for modification) is an alteration of the game and objective of modding. There's a large variety of mods, everything from small tweaks to total conversions.
Mod creators or players may create a wiki page for their preferred mod or tool, to act as a collaborative documentation of its features.
The mod installation folder is:
~\Documents\Paradox Interactive\Crusader Kings II\mod\
~/.paradoxinteractive/Crusader Kings II/mod/
~/Documents/Paradox Interactive/Crusader Kings II/mod/
Never install mods in Steam directory (ex: C:\Program Files (x86)\Steam\SteamApps\common\Crusader Kings II\mod), as mod would not be properly loaded.
In case of manual installation, the steps are usually the following (refer to specific mod instructions, if any):
- Remove any existing installation of the mod (mod folder and .mod file). This is very important, as the game loads all files present in mod folder, so old mod files that are no longer present or were renamed in a new version of the mod would conflict.
- Clear your gfx cache, by deleting the folder ~\Documents\Paradox Interactive\Crusader Kings II\<mod_name>\gfx, if any.
- Extract the downloaded archive, so that CK2 mod folder contains the .mod file and directory of the mod.
- Launch CK2 and select the mod in the Mod tab. Note that the mod may have a different name in the launcher than the name of the .mod file.
For more info, see the structure of a mod.
Incompatibilities happens when a mod:
- has to overwrite vanilla files, usually because of modding restrictions or limits to folder-based loading behavior.
- is a total conversion and/or major overhaul, and is deeply tied to vanilla.
In addition mods may be incompatible with each others, if they modify the same vanilla files or entities (graphic sprites, defines, ...). Refer to the mod FAQs for known incompatibilities.

Extended historical timeline
A subset of mods have tried to create additional historical bookmarks, in an attempt to extend the historical vanilla timeline covered by Paradox games.
The further away from vanilla timeframe and map scope the mod goes, the more mechanics and events need to be adapted or re-written to fit the period or location, and the more major the overhaul needs to be.
