In the Imperium, a marshal isn’t one thing. The title shows up in the Black Templars as a crusade commander, and in the Astra Militarum as a senior officer. This page focuses on the Black Templars marshal, the warrior who leads a crusade and answers only to the High Marshal.
What a Black Templars marshal does
A marshal commands a Black Templars crusade. Think of him as a captain from another Chapter, but with a key difference: the number of Space Marines under his command can vary wildly. Some crusades are huge, others are small and self-sufficient.
He’s a fanatical, experienced fighter who leads from the front. He answers to the High Marshal and no one else. Since the Great Rift tore the galaxy apart, communication with Chapter command has become so unreliable that many marshals effectively run their own mini-Chapters, making big decisions on their own.
- Commands a crusade, not a fixed company.
- Second only to the High Marshal.
- Leads from the front lines.
- Often operates autonomously due to warp disruption.
How you become a marshal
Most marshals come from the Sword Brethren, the Black Templars elite. They earn the rank through ritual combat, and the winner needs the High Marshal’s approval to take the title. That approval has been withheld at least once, during the Gervahrt Repeal in M36.
Other marshals are simply Castellans picked by a sitting marshal to succeed him if he falls. So there’s a formal path and a practical one, depending on the crusade’s needs.
Marshals and the wider Chapter
Some marshals crusade so far from home that they never meet their peers. In rare cases, they never even meet the High Marshal. But when something huge happens, all available marshals gather on the Eternal Crusader to vote.
That vote usually decides who becomes the next High Marshal. It’s also been called for major events like the Plague of Unbelief, the opening of the Great Rift, the return of Roboute Guilliman, and rumours of a knightly champion in Imperium Nihilus.
Notable marshals
The lore names many marshals, each tied to a specific crusade. A few stand out for their deeds or their unusual circumstances.
- Actoan: led a crusade against Golgotha in 996.M41 to wipe out Orks.
- Austein: commanded the Donian Crusade, killed by Orks on Nickel V in 988.M39.
- Bohemond: led a crusade to relieve Eidolica during the War of the Beast.
- Daidin: commanded the crusade where Helbrecht served, and was succeeded by him.
- Magneric: a Dreadnought who still served as Marshal of the Kalkator Crusade in M32.
- Marius Amalrich: commanded the Cruxis Crusade in the 13th Black Crusade.
Marshal in the Astra Militarum
The rank also appears in the Astra Militarum, but it’s a different beast entirely. There, a marshal is a senior officer, often in charge of large formations. The details vary by regiment and source, so don’t assume a Black Templars marshal and a Guard marshal share anything beyond the name.

- Marshals are usually chosen from the Sword Brethren through ritual combat, with the High Marshal’s approval.
- Since the Great Rift, many marshals operate as autonomous quasi-Chapters.
- All available marshals gather on the Eternal Crusader to vote on major decisions, including choosing a new High Marshal.
- The Astra Militarum also uses the rank of marshal, but for senior officers rather than crusade leaders.
FAQ
Is a marshal higher than a captain?
In the Black Templars, yes. A marshal leads a crusade and is second only to the High Marshal, while a captain in other Chapters typically commands a company. The Black Templars don’t use the rank of captain in the same way.
How many Space Marines does a marshal command?
It varies. A crusade can be as small as a few dozen or as large as several hundred. There’s no fixed number like a Codex company.
Can a marshal become High Marshal?
Yes. When the High Marshal dies, the available marshals gather on the Eternal Crusader and vote for a successor. That’s the usual way a new High Marshal is chosen.
