Your game begins by selecting a start date, the point at which the simulation begins to diverge from history.
You may choose one of the bookmark start dates below, or select any custom start date between 1066 and 1337.
Choosing a start date
As technology advances, large realms become more stable and merchant republics become economic powerhouses. Expect larger wars at later start dates, as crusades and jihads are called, and as hordes invade from off-map.
You may choose a character immediately, or use "observer mode" to mix things up before playing.
Each start date has its own major powers and regional dynamics. Learn how these historical realms tend to behave, and use this knowledge to form strategies and personal goals.
Early Middle Ages (769)
- Requires Charlemagne DLC
|Charles and Carloman Karling rule over a divided Francia. If Charles reunites Francia, as he did historically, he will be known as "Charles the Great" or "Charlemagne". He may aim to found the Holy Roman Empire.|
|In the Byzantine Empire, controversy rages regarding the use of religious images. The emperor and ecumenical patriarch are Iconoclast, but may revert to Orthodox Christianity by decision.|
|The Abbasid Caliphate is at the zenith of its power. However, powerful vassals are already biding their time to break free.|
Viking Age (867)
- Requires The Old Gods DLC
|In Scandinavia, small tribes are attempting to subjugate each other in the hope of forming Norway, Sweden and the Fylkirate.|
The sons of Ragnarr Loðbrok are attempting to carve out pieces of England in revenge for the murder of their father. Farther East, Rurik is beginning his attempt to form Rus.
While the Norse are powerful now, they are vulnerable to gavelkind and conversion by missionaries.
|King Arpad of the Magyars is beginning a series of invasions with the hope of settling in Hungary. Despite having massive event armies and access to the Tribal Invasion CB, the Hungarians often stay put after conquering de jure Hungary.|
|Six Karling kingdoms dominate Western Europe. Will enough Karling realms unite, through claim wars or inheritance, to create a new empire?|
|The Umayyad Sultanate of Al-Andalus controls 66% of Hispania, but Asturias has upgraded holdings and is therefore stronger than it looks. The Umayyads may inspire early Crusades if they successfully invade Aquitaine at Toulouse.|
|The Abbasid Caliph, Al-Mu'tazz, rules over a weakened Arabian empire. Former vassals have become de facto independent. The Caliph's half-brothers consider claimant bids, while the Turkish dukes in Jerusalem clamor for independence. Meanwhile, the Saffarids ruling Persia have less than 90 years to prepare for a Seljuk invasion.|
High Middle Ages (1066)
|The descendants of Rurik have converted to Orthodox Christianity. The continued practice of gavelkind has left Ruthenia and Rus a mess of independent duchies, but anyone who dares to attack one is likely to draw the ire of all Rurikid rulers.|
|The Holy Roman Empire and France are major powers. The Karling dynasty rules neither: they have been reduced to a single county, Vermandois in France. Hungary, Poland, and much of Scandinavia have converted to Catholicism. Although Catholic and feudal, the Hungarians have not forgotten the raiding ways of their forefathers.|
|King Harold of England is being invaded by two claimants: Duke William "the Bastard" of Normandy, and King Harald "the hard-ruler" of Norway. (This describes 15 September 1066, before the battle of Stamford Bridge. If you wish to start with William the Conqueror, select 26 December 1066 instead.)|
|The Sunni Andalusians rule small duchies in the wake of the disintegration of Al-Andalus. The Catholic Castilians in northwest Hispania have also split into multiple kingdoms, ruled by three brothers. How long will Hispania remain a fierce battleground of holy wars and Castilian infighting?|
|The Seljuk horde has swept through Persia and Mesopotamia, reducing the Abbasid Caliphate to a mere vassal duchy. But can they survive their rebellious vassals and the impending First Crusade?|
The Alexiad (1081)
- This minor bookmark can still be selected using a custom game.
|After failing to usurp Persia, Suleyman Seljuk conquered Anatolia and created an independent Sultanate of Rum.|
|Constantinople is in danger, but Basileus Alexios has the potential to be a strong Byzantine Emperor.|
Age of the Mongols (1241)
|The Golden Horde controls Tartaria. The Ilkhanate controls Persia. The steppe nomads' attentions are likely to be focused towards Eastern Europe.|
|A new merchant republic called The Hanseatic League has formed on the northern coast of the Holy Roman Empire. Venice and Genoa control large trade zones in the Mediterranean.|
Late Middle Ages (1337)
- Only start here if you like short games, or plan to export to Europa Universalis. Games of Crusader Kings end in 1453!
|The Hundred Years War between England and France is about to start.|
|The small Ottoman state in northwest Anatolia begins its rise to greatness as Byzantium declines.|
