Crusader Kings III has 56 different achievements, all using the Steam achievements mechanics. Achievements have no in-game effects; the achievement just pops up in-game, and is then added to the player's Steam profile.
The difficulty of each achievement varies; some achievements are very easy (e.g. Marrying another character), while some are more difficult (e.g. Reconquering all historical Roman territories). The below list groups the various achievements by a difficulty level as assessed by the wiki editors.
Achievements can only be gained in single-player Ironman games. They can be earned while playing older versions of the game as long as said achievements were present in that version. Playing game in offline mode (saving game in offline even once) permanently disables achievements for this savegame. Certain game rules will also disable achievements for the savegame; usually, such rules make the game easier.
It is not possible to gain achievements if the checksum has been changed - either by tampering with game files, or by running the game using mods that affect gameplay mechanics (graphical mods do not affect checksum), or a corrupted installation (the Ironman mode icon will change to reflect this).

|Is playing Duchess Matilda di Lucca of Tuscany in 1066|| Any dynasty member owns the Kingdom of Italy
||Start by obtaining the Duchy of Lombardy. Do not form the holy order until you have at least 50 members alive in your dynasty and hold the kingdom of Italy, otherwise the achievement will not trigger but fear not it can still be salvaged by simply revoking the holy order's right on the Barony you granted them and then re-making the holy order once more.||1.0||H|
|Missing unique ancestors is over 50.||This achievement can be problematic at times, as currently the AI has a tendency to cuckold a lot which can result in the achievement not firing when you hit the 3rd generation of sibling inbreeding. It's worth giving it a shot on the Iceland 1066 start, where you're rather isolated from most of the map, which reduces the chances of being cuckolded significantly. There, attempt to form a heresy with unrestricted divine marriage and then do 3 generations of sibling inbreeding to get the achievement.
Playing as the female sibling in each generation can help to verify that no secret cuckolding has occurred, as the player can control the character such that none occurs. To further guarantee this, suicide early in the previous generation's life to quickly take control of the female in the next generation.
Using the Asexuality or Homosexuality options for the Sexuality Distribution game rule also helps ensure that bastards are very unlikely.
