Excommunicate Your Rivals? CK3 Unlocks Playable Popes

Imagine spending decades building your dynasty, forging alliances through strategic marriages, and quietly poisoning anyone who stands in your way, only to have some Pope you've never met excommunicate you and tank your entire realm's stability. Now imagine being that Pope. Paradox Interactive revealed Crusader Kings III's Chapter Five yesterday, and the first of its two major expansions, By God Alone, will make theocracies playable for the first time in the franchise's history.

Lead designer Mikael Andersson laid it out plainly in the reveal video: "For the first time in the Crusader Kings franchise, we're also introducing playable theocracies, allowing you to rise to the power of the Pope himself." The expansion, arriving in Q3 2026 as a paid DLC, reworks CK3's religion systems with a heavy focus on Christianity. A new Rites mechanic models how local religious practices diverged from official church doctrine, creating friction between regional religious leaders and central authority. Those leaders risk being declared heretical, which means the Pope isn't just a background entity anymore; whoever holds that seat has real teeth.

I've been playing CK3 since launch, and the church has always felt like furniture. It's there, it occasionally causes problems, but you can't really engage with it as a system in any satisfying way. Making the papacy playable doesn't just add a new character type; it turns one of the game's most passive institutions into an active player in the political sandbox. Excommunication, taxation of temple holdings, triggering schisms: these are tools that could completely reshape how multiplayer sessions play out, and I'm excited to see how the community breaks it.

Silk & Silver

Chapter Five's second expansion, Silk & Silver, is scheduled for Q4 2026 and takes CK3 in a completely different direction. You'll play as the head of a trading company, establishing trade routes, securing monopolies, and undermining rival merchant families. It introduces a Republic government type where merchant families compete to shape the republic's constitution, pass laws, and form trade confederations with other republics for mutual commercial and military benefit.

Merchant republics were a fan-favourite system in Crusader Kings II, and their absence from CK3 has been one of the community's longest-running complaints. Paradox taking until 2026 to bring them back is a long wait, but the scope described here sounds significantly more fleshed out than CK2's version. Competing over constitutions and forming confederations suggests a layer of political simulation that goes beyond simply accumulating gold, which is what CK2's republics often boiled down to in practice.

The full Chapter V expansion pass costs $43.99 / £36.99 / €43.99 and includes both major expansions alongside two smaller packs available now: Symbols of Authority, a cosmetic clothing pack with new crowns and headwear for European characters, and Songs of the Realm, a music pack with thirteen tracks mixing remastered CK classics and traditional European music adaptations.

Paradox also dropped the free 1.19 "Scribe" update yesterday, which we covered in full. The patch adds a modular Stories system that surfaces special event chains more clearly, age-related ailments that gradually worsen over time, a colour picker for clothes in the Barbershop, and a Kingdom Come: Deliverance crossover that drops Henry into the game as an adventurer on certain start dates. Warhorse pushed a reciprocal update on their end, adding a "Three Crusader Kings" book to Kingdom Come: Deliverance II.

After Chapter Four extended CK3's map across Asia with Mongolian nomads, Chinese bureaucrats, and Indonesian god-kings, Chapter Five pivoting back to Europe's religious and mercantile power structures feels like Paradox filling in the gaps that have been there since launch. Playable popes and merchant republics aren't just new content; they're systems the game has needed for years. The pricing for the expansion pass is steep for content that won't fully arrive until Q4, but if By God Alone delivers on the promise of turning the church into a living political actor, it could be the most consequential CK3 expansion yet.
