Quick answer
Renown is your dynasty’s shared resource, earned by every living member and spent by the Dynasty Head on legacy tracks and Level of Splendor. There are eleven core legacy tracks (Warfare, Law, Guile, Blood, Erudition, Glory, Kin, Customs, Activities, Heroic Bloodline, Legitimacy), each with five unlockable legacies that benefit every member of your dynasty. Higher Level of Splendor makes marriages easier to arrange and raises your renown-gain caps.
A dynasty in Crusader Kings III outlives any single ruler, and Renown is how that continuity becomes mechanical power. Every generation quietly funds the next one’s legacy unlocks, and a well-managed dynasty compounds advantages no single reign could earn alone. This guide covers how Renown accumulates, what Level of Splendor does, and the legacy tracks available to spend it on.
What Renown is and how it accumulates
Renown is a resource accumulated by the whole dynasty, spent by the Dynasty Head on the most powerful dynasty-wide interactions, unlocking legacies and raising the dynasty’s Level of Splendor. Every living dynasty member contributes Renown continuously, with the rate scaling by title rank — an untitled member contributes a small trickle, while a count, duke, king, or emperor contributes progressively more, roughly doubling at each rank up. Landed rulers also generate Prestige for both the Dynasty Head and their own House Head at the same time, and marriage into the dynasty adds its own Renown contribution — being married to a ruler of another dynasty grants 80% of the Renown their primary title would otherwise generate.
Two caps matter for planning: Renown gain is capped based on how many non-ruler house members you have (capped around 100 members), and both Dynasty Head Prestige gain and House Head Prestige gain have their own separate caps. In practice this means a sprawling dynasty with many landed branches generates Renown fast, while a small, newly founded one builds slowly — patience in the early generations pays off later.
Level of Splendor
All Renown ever earned counts toward your dynasty’s Level of Splendor, a running reputation score that determines how well-known your dynasty is. The practical benefits compound as it rises: higher Splendor makes marriages easier to arrange, especially with dynasties of lower Splendor than yours, and it raises the caps on birth legitimacy, birth prestige, marriage prestige, and other bonuses tied to your dynasty’s standing. Splendor is built on named tiers — starting at Base Origins for a fresh or peasant dynasty and climbing through tiers like Obscure and beyond as required Renown thresholds are met — with each tier unlocking a better dynasty banner quality and higher caps across the board.
Level of Splendor is effectively permanent: it only decreases in the rare case of a player character attempting suicide, meaning ordinary play only ever moves it forward. This makes early Renown investment in Splendor a long-term compounding decision — a dynasty that reaches a high Splendor tier early enjoys easier marriages for every generation that follows.
Legacy tracks
Dynasty legacies are permanent bonuses the Dynasty Head unlocks with Renown, and every unlock benefits the entire dynasty, not just the Dynasty Head’s own branch. Each legacy track contains five legacies that unlock in sequence, and the tracks cover distinct areas of strength:
| Track | Theme |
|---|---|
| Warfare | Military strength and combat bonuses |
| Law | Governance and legal authority |
| Guile | Intrigue and scheming |
| Blood | Bloodline and genetic traits |
| Erudition | Learning, knowledge, and development |
| Glory | Prestige and renown generation |
| Kin | Family and dynasty relationships |
| Customs | Cultural influence |
| Activities | Grand activities and travel |
| Heroic Bloodline | Legendary ancestry |
| Legitimacy | Rulership legitimacy |
Two additional tracks unlock only for dynasties with North Germanic heritage or a culture descended from Norse — once the first legacy in one of those tracks is unlocked, the track stays available to the dynasty regardless of the current Dynasty Head’s culture afterward, so claiming one early preserves it for future generations even if your dynasty’s culture later shifts.
If an AI character becomes Dynasty Head, they will only continue unlocking legacies in whichever track already has the most progress — worth knowing if you are trying to predict or steer a rival dynasty’s development, or if control of your own dynasty passes to an AI-controlled relative between your player reigns.
Notable legacy effects
A handful of legacy unlocks are worth knowing by name because of what they enable. The first Adventure legacy grants Dynasty Heads the “Send to the Varangian Guard” interaction — for 350 prestige, an unlanded and unmarried dynasty member can be sent to serve the Byzantine Empire’s court and earn the Varangian trait, a classic path for surplus children who would otherwise sit idle in your court. The final Coterie legacy lets any dynasty member, including the Dynasty Head, disinherit their own children without spending Renown, at the cost of -30 opinion with all vassals — a blunt tool for succession planning that becomes available only very late in that track.
A legacy strategy
Early on, prioritise Renown generation itself: keep dynasty members landed where possible, since title rank multiplies their contribution, and do not neglect marriages, which add their own share. As Renown accumulates, decide whether to push Level of Splendor for the marriage and legitimacy benefits, or spend on a legacy track suited to your dynasty’s identity — Warfare for a martial dynasty, Erudition for a scholarly one, Blood for a bloodline focused on breeding strong heirs. Because legacies benefit every member permanently, an early investment pays dividends across every future reign, making dynasty legacies one of the strongest long-horizon investments available, alongside the cultural investments covered in the culture guide.
Frequently asked questions
How do I earn Renown faster?
Keep as many dynasty members landed as possible, since Renown contribution scales sharply with title rank, and encourage marriages into your dynasty, which also contribute. A large, well-landed dynasty generates Renown far faster than a small one.
What does Level of Splendor actually do?
It makes marriages easier to arrange, especially with lower-Splendor dynasties, and raises caps on birth legitimacy, prestige, and related bonuses. It is effectively permanent and only decreases in extreme, rare circumstances.
How many legacy tracks are there?
Eleven core tracks available to any dynasty, plus two additional tracks unlocked only for dynasties with North Germanic or Norse-descended culture. Each track has five sequential legacies.
Do legacy unlocks benefit the whole dynasty or just the Dynasty Head?
The whole dynasty. Every legacy the Dynasty Head unlocks applies to all members, which is what makes dynasty legacies a generational investment rather than a personal one.
