The Adepta Sororitas (also known as "the Sisterhood" or "Daughters of the Emperor") are an all-female subdivision of the religious organisation known as the Ecclesiarchy or Ministorum. The Sisterhood's Orders Militant serve as the Ecclesiarchy's fighting arm, mercilessly rooting out corruption and heresy within humanity and every organisation of the Adeptus Terra.
The terms "Adepta Sororitas" and "Sisters of Battle" are commonly assumed to mean the same thing, but the latter title technically refers only to the Orders Militant - the military arm of the organisation which is the largest and the best-known part of the Sororitas.

The Sisterhood serves as the Ministorum's only official military forces because the Decree Passive rules that the Ecclesiarchy cannot maintain any "men under arms". This was supposed to limit the power of the Ecclesiarchy. However the Ministorum were able to circumvent this decree by using the all-female force of the Sisterhood.[Needs Citation]
There is naturally some overlap between the duties of the Sisterhood and the Inquisition; for this reason, although the Inquisition and the Sisterhood remain entirely separate organisations, the Orders Militant of the Sisterhood are the go-to favoured option when an Ordo Hereticus Inquisitor needs soldiers. 
Daughters of the Emperor
The Adepta Sororitas were officially founded in the 36th Millennium, and more specifically during the later Age of Apostasy.[1a] However, they trace their origins to an older, all-female warrior cult known as the "Daughters of the Emperor". Based on the world of San Leor, this cult was dedicated to worship of the Emperor and the study of martial arts. The Daughters were fairly isolated from the wider Imperium,[25e] but there are accounts which suggest that they did not stay on San Leor all the time. For instance, Imperial scholars believe that Saint Sabbat was linked to the Daughters of the Emperor in some way.[25f] It is possibly that the Daughters fought in her war for the Sabbat Worlds.[14c][25f]
Regardless, the Daughters of the Emperor remained a small sect and mostly unknown cult until they were discovered by the spies[25f] of Goge Vandire, the High Lord of the Administratum (and also Ecclesiarch of the Adeptus Ministorum). Realizing their potential usefullness, he decided to visit San Leor and recruit the Daughters into his own private army.[25e] The Daughters at first refused to accept his authority. Vandire decided to show them that he was blessed by the Emperor - he instructed a soldier in his entourage to shoot him, which after a brief hesitation, he did. However, thanks to the protective field generated by the Rosarius of the Ecclesiarch (which no one but Vandire himself was aware of), Vandire was not harmed. The Daughters took this to be a sign, and swore allegiance to Vandire virtually on the spot. They were renamed the Brides of the Emperor, and became Vandire's most loyal followers.[1a]
Revelation and retribution
During the Siege of the Ecclesiarchal Palace, the Adeptus Custodes, the praetorians of the Emperor himself, tried to approach the Brides and convince them of Vandire's treachery. In a last ditch effort to convince them, the Custodes took Alicia Dominica, leader of the Brides, and her chosen bodyguards deep into the Imperial Palace where they stood before the Emperor himself. What happened there remains unknown - Dominica and her companions were sworn to secrecy - but it became clear that the Brides, who reverted to the title of Daughters of the Emperor, had been awakened to the evil that Vandire represented. Marching into his audience chamber, Dominica paused only to condemn Vandire for his crimes before she beheaded the power-crazed dictator. Reportedly, Vandire's final words were "I don't have time to die - I'm too busy!"[1b]
After this episode, the newly appointed Ecclesiarch Sebastian Thor proclaimed the Decree Passive which forbade the Ecclesiarchy from having "men under arms". Under the literal interpretation of the decree the Adepta Sororitas, being female, were not obligated to disband. Thor, recognising the need for the Ecclesiarchy to have some kind of force and internal regulator, allowed them to remain even if the spirit of the decree was rather blatantly disregarded.[1c]
- 378.M36: Ecclesiarch Alexis XXII, Sebastian Thor's successor, divides the Orders Militant of the Convent Sanctorum and Convent Prioris into four Orders[1d]:
- M36: After the death of Alicia Dominica, Ecclesiarch Equitus XI presides over the creation the rank of Abbess of the Adepta Sororitas, the new leader of the Adepta Sororitas. The first to hold the position is Sister Palmiro of the Order of the Holy Word.[3c]
- 878.M38: Ecclesiarch Deacis VI founds two more Orders Militant in honour of the remaining two saints who accompanied Alicia Dominica to the Golden Throne - the Order of the Bloody Rose in honour of Sister Mina and the Order of the Sacred Rose in honour of Sister Arabella.[1d]
- M41: Sister Sabrina of the Order of the Ermine Mantle is elected Abbess but disappears during her pilgrimage to San Leor. The position of Abbess was vacant[3c] until after the return of Roboute Guilliman when it was reestablished.
- M42: The Adepta Sororitas embark on an unprecedented number of Wars of Faith in the aftermath of the formation of the Great Rift and Indomitus Crusade. A new Abbess, Morvenn Vahl, is appointed by Roboute Guilliman.
Structure and Hierarchy
The Adepta Sororitas is part of the Ecclesiarchy and is divided between two Convents - the Convent Prioris located on Terra and the Convent Sanctorum based on Ophelia VII, although in practice their forces are spread throughout the Galaxy.[1d]
The overall commander and spiritual leader of the entire Sisterhood is the Abbess of the Adepta Sororitas. As the leader of the Adepta Sororitas, the Abbess is sometimes elected into the High Lords of Terra.[2d]
The Convents of the Sisterhood are organized into several Orders. There are two different kind of Orders: The Orders Militant, or Sisters of Battle, the military arm of the Ecclesiarchy composed of the six Major Orders and countless subsidiary Lesser Orders Militant; and the Non-Militant Orders, each of which has different roles and responsibilities in the Imperium.[19a][19b]
The largest of the Non-Militant Orders rival the Sisters of Battle in size and notoriety, but there is also hundreds of other orders, the vast majority of which are unknown to the bulk of Mankind. The most well-known are the Orders Hospitaller, composed of surgeons, physicians and nurses, the Orders Dialogous, scholars dealing with languages, cyphers and translations, and the Orders Famulous, acting as diplomats, chamberlains and advisors for Imperial noble families[1d][1e]
It is not uncommon for a Sister to transfer from one of the Orders to another, particularly if a Battle Sister has become injured or is too old for combat they may transfer to one of the non-militant Orders.[3a]
Each of the major Orders follows the same basic hierarchical structure[2c]:
- Order - Led by the head Canoness, called the Canoness Superior, who runs the entire Order.
- Preceptory - A subsidiary convent or a large tactical detachment with up to 1,000 Sisters led by a Canoness Preceptor.
- Commandery - Normally smaller convents or detachments of militant Sisters with up to 200 Sisters, led by a Canoness Commander.
- Mission - The smallest organisation of Sisters, consisting of a few units and can be led by a Canoness or the lesser Palatine.
It should be noted that the non-militant Orders operate mainly at Mission and Commandery levels - Preceptory is a largely organisational tier. For example, a Commandery of the Order Hospitallier could be a staff of sisters working in a field hospital whilst a Mission of the Orders Famulous could be a handful of Sisters engaged in a trade delegation.[2c]
Commonly known as the Sisters of Battle, the Orders Militant are the most numerous and well known of the Adepta Soritas. They are the only official fighting force of the Ecclesiarchy and often prosecute Wars of Faith. They also form the Chamber Militant of the Ordo Hereticus and often fight alongside the Inquisitors of that Ordo.[2b][2c]
|Convent Sanctorum (Ophelia VII)||Convent Prioris (Terra)|
|Order of the Bloody Rose||Order of the Sacred Rose|
|Order of Our Martyred Lady||Order of the Ebon Chalice|
|Order of the Valorous Heart||Order of the Argent Shroud|
Lesser Orders Militant
Since their founding the Major Orders Militant have established a number of subsidiary convents at sites significant to the Ecclesiarchy. Sometimes little more than small Garrisons, these bases have developed identities distinct from their parent Orders over time, eventually becoming separate Orders all together. These smaller Orders are referred to as the Orders Minoris or Lesser Orders Militant. In theory the leaders of the Lesser Orders are answerable to the leaders of the Major Order that spawned them.[2a]

Heretical Adepta Sororitas
Though it is rare, Adepta Sororitas have fallen to Heresy and been corrupted by Genestealer Cults, despite the Imperium's public declaration that it is not possible. Once this occurs, the Sororitas' Orders go to great lengths to both prevent it from becoming known and to remove the stain on their honor. This includes hunting the heretical Sisters down and having them quietly killed, while also having their existence erased from the Imperium's history. Some Orders even have a pure Sister, undergo surgery to assume a Heretic's face and identity, in order to keep the truth from being discovered.
Known Chaos-corrupted Adepta Sororitas
- Miriael Sabathiel, Order of Our Martyred Lady Sister Superior who is belived to be the first Sister to fall to Heresy.
- A number of Sisters from the Order of the Argent Shroud, who were captured by Miriael Sabathiel and corrupted into Heresy. These Sisters then served in Sabathiel's warband.
- The Iconoclast, originally the Order of the Valorous Heart Celestian Oleande.
