Community25 Aug 2026"By God Alone" Dev Diary #5 - Investiture ControversyHello everyone! In today’s dev diary, we’ll explain how a historical conflict between the church and monarchs, known as the Investiture Controversy, is translated into Crusader Kings III, and also serves as one of the seven chapters in the new Christian Church situation of By God Alone. Your feedback from earlier dev diaries regarding this subject has been especially helpful, and we thank you a…
In the latest episode of our ongoing documentary series, medieval historian Eleanor Janega explores the real history at the heart of our upcoming Core Expansion for Crusader Kings III: By God Alone . Filmed inside one of London’s oldest medieval churches, this video enters a world where the Church did more than shape belief: it helped decide who held power, who could be challenged, and what cou…
Rule kingdoms. Wear the trauma. The medieval era wasn't pretty, and neither are you. Crusader Kings III has teamed up with Dogecore to bring you a collection that captures every glorious, cursed corner of the game you know and love. From hoodies and tees to tote bags and posters, this drop is for the player who's lost an heir to smallpox, tortured a vassal into submission, and somehow still cal…
Greetings! You may remember me from the days of Khans of the Steppe, but today I am here to welcome you to another By God Alone dev diary. When we set out to rework how Christianity feels in Crusader Kings III, we kept returning to the same question: how do you make a thousand years of Church history feel alive in a sandbox, without turning every playthrough into the same timeline? Our answer i…
Navigate through a medieval era with a rich religious life in Crusader Kings III: By God Alone , our latest Core Expansion releasing on September 30th ! Wrestle with sin as your rulers try to live up to the tenets of their faith and tangle with church authorities who have power on earth, as well as heaven. Instigate or settle religious debates, negotiate the limits of crown and Papal authority,…
Greetings! Alexander Oltner here, Game Director for Crusader Kings III. Today's diary is a little different from our recent ones, in that it's not about a new mechanic we're building for an expansion, but about something we've already made. So, let's talk about Landless Adventurers! When we first designed Landless Adventurers, we envisioned them as a transition state , something you'd hop into…
A Genius would have claimed this weeks ago. A Lunatic would have forgotten entirely. Either way, your last chance is here. We partnered with Makeship to bring two of CK3's most iconic traits to life as a dual pin set. Whether you're the calculated ruler who schemes three wars ahead, or the unpredictable wildcard your council fears, there's a pin for you. The Genius & Lunatic Pin Pack limited ca…
Hello there! Today, we are going to take a look at republics. We talked a little bit about them in both the announcement video and the original Silk & Silver vision dev diary, but today we will go a bit more into the weeds. Without further ado, let’s get started. \ To start us off, what are republics? Republics in Silk & Silver are effectively small city-states, with all the “relevant” people w…
Hi all! I’m PinkAxelotl. Today, we’re taking a look at our vision for Merchants in Silk and Silver. Who are they, what is the experience they provide, which are the relationships that matters to them the most, and what specific systems are used to support their gameplay? For the purposes of this Development Diary, the term “Merchant” only includes the new landless Merchant government. We won’t…

Happy Tuesday! Mikael here with another By God Alone update. Last time we walked through Ecclesiastical Titles and Rites and while we shone a light on clerical gameplay and faith mechanics, we did not really touch on how a secular character - who you as the player, most often control - can harness said clerical mechanics. So let's go there! The year is 1075. You are the King of West Francia, an…
Greetings! I’ll be following up on the overall vision dev diary with a deeper dive into our design for the Trade System. We’re starting our feature-specific dev diaries with Trade because, as you’ll see, it is connected to nearly every other feature we’re developing for Silk & Silver . But before we get into it, remember that all screenshots are work-in-progress and we are in the middle of deve…

Happy Tuesday! Mikael here again with another update on the development of By God Alone . Last week we talked a lot about Rites , and this week we're going to talk about their finer details - how they start, how they spread, how they go wrong, where the line is between local devotion and outright heresy. We're going to keep that promise, but we're also going to come at it sideways, because Rite…
Happy Tuesday, and welcome to our first official dev diary for our upcoming expansion By God Alone! In our sneak preview , we gave you the grand tour from the mountaintop.

Hello everyone, and welcome to a very special dev diary! Today we finally get to pull back the curtain on what we're cooking up next for Crusader Kings III.

The Son of Heaven surveys his vast dominion. Robed in splendor and seated in quiet authority, he is the unquestioned master of all he sees. Every glance carries weight. Every pose suggests absolute command. Fearsome. Regal. Unyielding. However, behind the imperial grandeur, beneath the stern expression and all the majesty, there is another side to the Emperor Platypus. A softer one. A gentler o…

Heya y’all! My name is Riad. You may know me as the QA guy who sometimes posts on Reddit, or the guy who showed off the Black Forge Jam projects last year… or, more recently, the guy who wrote that apology . Yeah. Since then, a lot has happened for us at Studio Black. We released our biggest expansion ever, All Under Heaven , which added many long-missing parts of the world to Crusader Kings II…
