Depictions of the various Knightly Orders (or Crusaders).
Quite a few people consider the Brotherhood of Steel's Capital Wasteland government as an Ordensstaat, however the use of such a term, and its justification on the wiki, is incorrect.
I'll put on my historian hat and explain why. This is not about just changing the explanation on the wiki, but more of an explanation to the community about the difference of such a word in correct historical terms. I also had quite the discussion with my girlfriend (who is German) about the correct term to use, and I have arrived at my conclusion thanks to her.
Here are some historical facts for all of you to consider. If you're bored, then believe me, I have to write a dissertation on the topic of the Crusades, so bear with me.

An "Ordensstaat" is not a form of government. It's the short term for Deutschordensstaat ("German Order State") which was the name of the Teutonic Order's (German Order) lands for German speakers. In German, this is all it refers to and all it means, as no other Germanic states have called themselves this.
State of the Teutonic Order from 1260-1410 CE.
(Key: Dark orange is territory acquired in 1309 CE. The lighter shade of orange is territory acquired in 1346 CE. The lightest shade is territory acquired as late as 1402 CE.)
Variations of the Teutonic Order's name in German are Deutscher Orden, Deutschherrenorden and Deutschritterorden.
In fact, there's something of a negative connotation for the phrase "Deutscher Orden" after 1945, as it was at one point the name of the highest award the Nazi Party bestowed on individuals for service to "state and party".
Interestingly, the German inhabitants of the Holy Roman Empire did a similar thing with that respective state, calling it das Heilige Römische Reich Deutscher Nation, meaning "The Holy Roman Empire of the German Nation".
Knights from the Teutonic Order sometimes bore an eagle similar to the Holy Roman Empire, as they owed allegiance to them.
The military orders that had similar states, such as the Knight Hospitallers (also known as the Knights of Rhodes) and Knight Templars, were collectively known as the Crusader States (DE: "Kreuzfahrerstaaten").
The first real Crusader States, or Kreuzfahrerstaaten, before expansion in Europe.
The first Crusade was initiated by Pope Urban II to protect the Byzantine Empire, which was under attack by Muslim Seljuk Turks. (1096-1102 CE)
They were never known as "Ordensstaats" or "Order States". All "Kreuzfahrerstaaten" operated in a very similar manner. There were no real distinctions between one another except the conventions upheld by each individual knightly order, who operated as a type of policing force that guarded roads, towns and their headquarters (Singular: Commandery, or Kommandantur, still used today).
The Crusader States typically refer only to the territory administered by these factions in the Middle and Near East during the Crusades, however they survived and flourished for a time in Europe, including the Teutonic Order in parts of Old Prussia and beyond, where they were still referred to as holy knights and crusaders, hence the singular word Kreuzfahrerstaat, or Crusader State.
The Crusades were never truly restricted to simply the Near and Middle East after this, as Crusaders expanded throughout Europe and fought nations such as Lithuania and Poland to christianise under Papal and Holy Roman authority.
Commanderies (castles administering land) of the Knight Hospitallers circa 1300 CE. The island in red in the bottom right corner is Rhodes, the signature land owned by the Knight Hospitallers, who later became Knights of Rhodes after the schism of Catholicism and Protestantism, with Knight Hospitallers taking both sides and losing most European territory.
Military orders in religious society are also known to be Christian religious societies of knights (latin: militaris ordinis). These orders would defend the Crusader States, also known as "chivalric orders" for their knightly code.

One knightly order missing from the previous picture are also the Knights of the Holy Sepulcre.
Calling the Brotherhood's territory an "Ordenstaat" is like calling the NCR's form of government the Republic of Athens in Greek. It's fundamentally incorrect.
It's more accurate to call the Brotherhood's (and the Teutonic Order's) land a "Crusader State", being formed and protected by religious warriors, or literally protected by an Order of knights and religious warriors. Translated into English, "Order State" is incorrect, as it is not a form of government recognised by historical, historiographical or governmental academics.
However, @ThreeSecondRush believes that the reason why people would perhaps not associate the Brotherhood's territory as a Kreuzfahrerstaat is because of the negative connotation surrounding genocide and the holy conquests.
The correct name is "German Order State" (because the Teutonic Order was also called the German Order), which references the historical order, whom the Brotherhood are not imitating in the slightest. The full name for the Teutonic Order in German was Orden der Brüder vom Deutschen Haus der Heiligen Maria in Jerusalem. ("Order of Brothers of the German House of Saint Maria of Jerusalem")
History has never seen any other "Ordenstaat", as that would mean another iteration of "German Order State", but it was a Kreuzfahrerstaat.
The Brotherhood don't run their land like the Teutonic Order did (that we know), as you had to have certain social standing in the aristocracy in order to join their ranks as fledged knights.
The only similarity is that the Papal State and the Holy Roman Empire sanctioned the Teutonic Order in the same way that the Western Elders sanction the East Coast Brotherhood. That, however, is no real similarity in governance.
The Teutonic Order explicitly protected Christians that swore allegiance to God, and I don't believe the Brotherhood demands of everyone that they swear allegiance to Roger Maxson. Therefore, the correct term is "Crusader State", or if you'd like a fancy German word for it..
Kreuzfahrerstaat.
What do you guys think? I hope you enjoyed the post!
