Achievement

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. If the Ruler Designer was used, achievements can still be obtained as long as no more than 400 customization points are spent.

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).

In 1066 King Alfonso VI has his own heir, King Sancho II, as his rival who will want to kill him for his titles. Make Alfonso's high intrigue lover, Urraca, as his spymaster to protect him until he has the needed perk and other lovers. Then break up with her to make her angry. She will likely join Sancho's plot and thus making the assassination attempt significantly more likely to succeed. Do not marry for legal children or legitimize bastards, as this may cause Sancho to not attempt an assassination plot as he will no longer be Alfonso's heir.		1.0	E

Playing as him, focus on getting the Kidnapper perk and then kidnapping the French king, your liege. Before that, you can fabricate a Hook on the king to become his spymaster when you're ready to abduct him, for greater Scheme Power. Once he's in jail, start an independence faction and immediately send an ultimatum—the king won't be able to refuse, as he's your prisoner. This makes you an independent Karling count, which technically counts as consolidation.		1.0	VH
Way of Life Complete an entire Lifestyle (all three trees)	Does not have the full set of lifestyle traits in a tree: Has neither: Diplomat, August and Patriarch / Matriarch Schemer, Seducer and Torturer Whole of Body, Scholar and Theologian Strategist, Overseer and Gallant Avaricious, Architect and Administrator	Has a full set of lifestyle traits in a tree: Diplomat, August and Patriarch / Matriarch Schemer, Seducer and Torturer Whole of Body, Scholar and Theologian Strategist, Overseer and Gallant Avaricious, Architect and Administrator	Use the Ruler Designer to create an 18-year-old character with the highest Education Trait and Genius. This greatly speeds up perk acquisition while giving you plenty of time to complete the three trees. If you don't plan on doing anything else in the playthrough, the Learning education and perk trees are recommended for the health boosts.		1.0	E

You can be from any faith except Orthodox or Iconoclast. This achievement is easiest obtained by starting as Jarl Haesteinn in 867. He can convert to French culture right from the start, which conveniently also gives access to siege weapons. Conquer the County of Napoli to be within range of Byzantium and prepare to invade them. If Byzantium allies with West Francia, swearing fealty to the French will prevent them from defending their Byzantine allies when you declare war. Then use the Conquer Kingdom (Thessalonika) Casus Belli. It is possible to do this achievement by starting as the Byzantine Empire, obtaining a second Empire title, and destroying the Byzantine Empire title. Then send your heir to be educated as French Catholic and wait until you play as them.		1.0	M
Going Places As Haesteinn of Montaigu in 867, hold any Kingdom tier title	Is playing Count Hæsteinn of Montaigu in 867 and is still alive.	Own a Kingdom title or higher.

You can start multiple murder plots to stress suicide Rurik, allowing you to play as his only heir, a 17 year old who also uses the martial tree.

A strategy you can use to get this fast is to apply the "North Korea" strategy, where you imprison and revoke all land from all your vassals until none are left anymore, in which the achievement will be triggered and earned. A bit simpler approach is to revoke all the duchies of non-English vassals and transfer non-English counts to English dukes if you have at least one in the realm - the achievement checks direct vassals only. If you have an Anglo-Saxon child as a duke vassal, you can educate them and convert culture.		1.0	M

The Emperor's New Clothes While holding any empire title, be naked		Own an Empire title. Is naked.	The easiest way to obtain the achievement is by using the ruler designer to replace an emperor (such as the Holy Roman Emperor) with an Adamite character.		1.0	M
Trapped in the Web Have strong hooks on three direct vassals		Has 3 strong hooks on vassals.	Using the predominant Homosexuality game rule, choose a ruler under a faith which criminalizes it—Björn Ironside in 867 is a safe option—then wait a few years for vassals to start their criminal love affairs for you to find. Also, with the Truth is Relative perk, your spymaster can fabricate Strong Hooks with the Find Secrets task. The task typically fabricates Hooks on courtiers, not rulers, but you can use it to get Hooks on your own courtiers and then land them.		1.0	M
A Name Known Throughout the World Have your dynasty reach the highest possible Level of Splendor		Have max splendor level for the dynasty.	In 1066, members of the Pugyel Dynasty in Tibet start with Famous Level of Splendor.		1.0	H

Taken the Avenge the Battle of Tours decision. Completely controls Iberia.	Any Muslim starting with the right culture and their capital in Iberia can do this achievement. Note: This is not possible to achieve currently with most Iberian Muslims in 867 start as they're Bedouin culture. You can, however, use the character creator to make a Muslim ruler who is, e.g. Visigoth, and start as the Umayyad caliphate in 867. That will allow you to satisfy the achievement.		1.0	H

Blood Eagle Starting as any child of Ragnarr Lothbrok, conquer all of the British Isles	In 867 is playing as either: Duke Björn Ironside of Uppland Duke Ivar the Boneless of the Isles Duke Halfdan Whiteshirt of Jorvik Duke Sigurdr Snake-in-the-Eye of Sjælland Ubbe Ragnarrsson	Completely control the Empire of Britannia (Only need to hold the region of Britannia, do not need to hold the empire title)	Children of Ragnarr Lothbrok are present in 867: Jarl Ivar 'the Boneless' of the Isles, Scotland Jarl Björn 'Ironside' of Uppland, Sweden Ubbe Ragnarrson Ubbing (unlanded; court of Halfdan) Jarl Halfdan 'Whiteshirt' of Jórvík, England Jarl Sigurd 'Snake-in-the-Eye' of Sjealland, Denmark		1.0	H
End of an Era Play until 1453		Date is 1453.1.1	Starting in 1066 reduces the necessary time. Playing a game for this long makes most of the milestone achievements, such as Saint, Monumental or Prolific, rather easy to get, so consider combining all of them in a single playthrough.		1.0	H

Once your war enemy is your prisoner, you get 100% war score. (Note: this may not be possible after the patch that made it much more difficult to abduct a war target)		1.0	H
Last Count, First King Starting as Duke Nuño of Portucale in 1066, form Portugal	Is Playing Duke Nuño Mendez of Portucale in 1066 and is still alive.	Owns the Kingdom of Portugal Is Playing Duke Nuño Mendez of Portucale.

Note that you will still have to defeat several Muslim neighbors in order to form Portugal.		1.0	H
Paragon of Virtue Have three or more virtuous traits		Have 3 virtuous traits.	Use the character creator to create a new ruler and give them the virtuous traits of their faith.		1.2	H

Reconquista Starting as an Iberian Christian, convert all of Iberia to Christianity	Is either from the Iberian culture group or has Andalusian culture. Is Christian	Completely controls the Iberia region All counties in the Iberia region is Christian Is from the Iberian culture group or Andalusian Is Christian	This achievement does not require being Catholic, only Christian. It can be faster to complete this by converting to or creating a new Christian faith that has faster conversion tenets and doctrines and higher fervor. The Theologian tree in the Learning lifestyle offers 20% faster conversion and the ability to ignore fervor when converting. Landing learning lifestyle characters can make the process of conversion faster as well, if they take those perks. Don't forget about the islands (e.g., Ibiza) east of the Iberian Peninsula.		1.0	H
Sibling Rivalry Starting as any of the Jimena siblings in 1066, become Emperor of Spain	In 1066, is playing either: King Alfonso VI of León King García of Galicia King Sancho II of Castille Countess Urraca of Zamora Elvira	Owns the Empire of Hispania	The achievement does not require total control of Spain, only enough to create the Empire of Hispania title. Alfonso of León is a high Intrigue character—with some luck and preparation you can kill your two brothers within two years to get their kingdoms (you might need to wait a few months after starting the game before agents are willing to join your murder plots). Then, press your claim on the Kingdom of Navarra. At this point, you can use the Unite the Spanish Thrones decision to unite León, Galicia, Castille and Navarra, giving you a strong core from which you can expand into the rest of the Iberian peninsula. It is not necessary to complete this achievement in one character's lifetime.		1.0	H
Wily as the Fox Starting as Robert the Fox in 1066, rule Sicily, hold a Greek Kingdom, and convert it to Catholicism	Is playing Duke Robert de Hauteville of Apulia in 1066	Owns the Kingdom of Sicily One of the following: Completely Controls the Kingdom of Epirus All Counties are Catholic Completely Controls the Kingdom of Thessalonika All Counties are Catholic Completely Controls the Kingdom of Hellas All Counties are Catholic	Start by obtaining enough gold to create the Duchy of Calabria and then the Kingdom of Sicily, then focus on Kingdom of Epirus. The achievement does not require you to be independent, so it is possible to swear fealty to the Byzantine Empire, obtain the Religious Rights feudal contract via hook, and conquer and convert the required provinces as a vassal.		1.0	H
Give a Dog a Bone Starting as Matilda di Canossa in 1066, rule Italy, have 50 Dynasty members, and found a Holy Order	Is playing Duchess Matilda di Lucca of Tuscany in 1066	Any dynasty member owns the Kingdom of Italy Have 50 living members of the dynasty. Create a holy order.	Start by obtaining the Duchy of Lombardy.		1.0	H
A Perfect Circle Have only two distinct parents, grandparents, and great grandparents		Missing unique ancestors is 50 or more.	Does not require two distinct grandparents or great-grandparents. Requires having no more than 12 unique characters among the player's parents through great-great-great-grandparents (the maximum possible is 62; 62 − 50 = 12). If there is no recorded parent, as for lowborn, it's counted as a whole tree of unrelated ancestors. Start in Iceland with the restricted diplomatic range rule, where you're rather isolated and can be left alone. Use the Ruler Designer to create a character of the Messalianism faith with the Divine Blood trait, then inbreed siblings for three generations. The greatest threat to this achievement is cuckoldry. Playing a female ruler (easy as Messalianism is gender-equal) together with the predominant Homosexuality or Asexuality rules can alleviate this.		1.0	VH
Mother of Us All Starting as Daurama Daura, have your line reform an African faith, and convert all of Africa to it	Is playing Countess Daurama Daura of Kano in 867	Has reformed and converted all African Counties to one of the following religions: Siguism Bidaism Orisa Bori Roog Sene Akom Kushitism Waaqism	Reforming the Faith with the Fundamentalist doctrine and the Mendicant Preachers, Reincarnation and Sanctioned False Conversions tenets will increase the realm's conversion speed and resistance. Revocable Clergy appointment doctrine allows you to select a priest with higher learning to speed up manual conversion. Try not to overuse Holy Wars, for they decrease fervor and at 40% or less there can be a heresy outbreak. Also, ensure that all of the vassals in your realm (at every level) are converted to the proper faith. Moving your capital to Cairo and converting to Egyptian culture lets you feudalize early and obtain an advantage that may be necessary to expel the Abbasids or Byzantines from Africa. Note: you do not require to convert provinces with your heretic religion (old <religion name>) to get the achievement. (Tested on Version Argent 1.2.2) You can still get the achievement if some of your provinces are heretic. All heathen provinces must be converted.		1.0	VH
Rise from the Ashes Restore the Roman Empire		Own the Roman Empire.	Must either be the Byzantine Emperor or Emperor of Italia and have taken the Unify Italy Major Decision. Must be feudal, a republic or a clan government. Must be an independent capable adult. Must not be imprisioned. Must have 5000 prestige, completely control the duchies of Latium, Venice, Romagna, Sicily, Genoa, Capua, Apulia, Thrace, Antioch, Palestine, Athens, Tunis, Croatia and Thessalonika. Must either be Christian or Hellenic faith or Roman culture. The easiest start is 1066 Byzantium - after surrendering to the Seljuks, you can declare De Jure wars for Croatia, the Sicilian counties and Venice; Holy wars for the African/Middle East ones. Claim Latium manually - wait for the Duchy claim event and be swift before the Pope hires too many mercs. Rush Divine Right to get both Genoa and Romagna (they need to be claimed manually as well) in a single war with the HRE.		1.0	VH
What Nepotism? Have your Dynasty rule ten independent realms of at least Kingdom tier simultaneously		At least 10 dynasty members are independent and own a Kingdom title or higher.	The Karling dynasty in 867 offers the best feudal start. This is probably easier to do while tribal, though, because it grants you extra CBs and the confederate partition is no problem.		1.0	VH
