BROTHERHOOD OF STEEL (BOS) IN STARFIELD

"AD VICTORIAM, SEMPER INVICTA" (TO VICTORY, ALWAYS INVINCIBLE) - the official motto of The Brotherhood of Steel

Back in the day, the Fallout series was a huge success for Bethesda Game Studios, contributing their development of their newest game, Starfield. One of the key interesting aspects in the Fallout universe (which includes Starfield), is the Brotherhood of Steel, one of only two known absolute monarchies in the Settled Systems, the others being House Va'runn, which was founded by its first Spriritual Leader of the Great Serpent, Jinan Va'runn.
The Fallout series, which began in 1997 with the release of Fallout 1 (developed by now-dormant Black Isle Studios), propelled their success in the genre of action role-playing video games.
By 2007, Bethesda acquired the rights to the Fallout series with Todd Howard was being responsible for the development of Fallout 3, which was rleeased in October 2008 and it was seen as the brilliant transition of the series' traditional 2D graphics (as it was seen in 1997's Fallout 1 and 1998's Fallout 2) to more straightforward 3D graphics that have been seen since Fallout 3's release.
Since the release of Starfield, there is a much more positive theory suggests that the Brotherhood of Steel maintained its larger presence in the Alpha Centauri system after the partial destruction of the planet Earth caused by the Great War of 2077 and its complete destruction in the year 2155.
Its capital city outside the Great Starstation Cygnus is New Citadel, which the Brotherhood of Steel named the capital city in Jemison since the year 2230 (1940 AD), replacing the aging populous and capital city of Maxsonville in Jemison, existed during 2165 through 2230, where it was destroyed by the United Colonies as it was turned into a mostly industrial and manufacturing city within the Brotherhood of Steel presence in Jemison.
Starfield is offically being the true sequel to the Fallout series, which takes place in the 2330, 43 years after the events of Fallout 4.
The phrase "Ad Victoriam, Semper Invicta" (which means "To Victory, Always Invincible" in Latin) had been officially recognized by the fans of Fallout series and Starfield as the official motto of the Brotherhood of Steel.
The term "Ad Victoriam, Semper Invicta" was coined by the first Brotherhood Supreme Elder Roger Maxson in 2078 refering to his past victory against the Chinese Army during the Battle of Anchorage, and it became the Brotherhood's official motto since its 2081 founding.
Most gamers and many fans of the Fallout series considers the Brotherhood of Steel and their role in Starfield as an "absolute imperial monarchy with full religious theocracy, technological hierarchy, and military hierarchy" in the Settled Systems.
In Bethesda's newest game Starfield, the Brotherhood of Steel is currently the only known monarchy in the Settled Systems, with the ruler or monarch of the Brotherhood of Steel uses the title of "Supreme Elder". Great Starstation Cygnus (until 2170 it was called Starstation Cygnus and John Maxson added "Great" to reflect Brotherhood's rich history), located near the planet of Jemison, is the seat of Supreme Elder.
Maintaining their ties with the United Colonies since the year 2162, plays the significant history of the Brotherhood of Steel and the Brotherhood considers the United Colonies as their only political ally with completely unbroken relations.

HISTORY OF THE BROTHERHOOD OF STEEL
By 2077, the Great War had partially destroyed the Earth's infrastructure and threatening their everyday lives. In 2081, a man known as Roger Maxson established the Brotherhood of Steel, but first as a military organization until it was quickly elevated into an imperial monarchy (with most religious ideals of Roger Maxson and traditionalist form of military hierarchy) by the year 2100 with Roger Maxson as the first Supreme Elder.
Throughout its 250-year history, the Brotherhood of Steel maintains its larger presence in the Settled Systems with their turbulent history, such as the Brotherhood Civil War (2231-2238), the Brotherhood-Enclave War (2267-2280), and the Colony War (2307-2311).
The Enclave (now Great Enclave) maintains its diplomatic and economic relations with the Brotherhood of Steel since its 2081 foundation by Roger Maxson, even before the Brotherhood's official establishment of its relations with the United Colonies in 2162.
During John Maxson's reign, the Brotherhood established its relations with the United Colonies in 2162 (which remained unbroken on its 168-year diplomatic history) to provide a larger diplomatic and economic support for the Brotherhood.
In 2319, Owyn Lyons became the first Brotherhood Supremer Elder to establish its diplomatic and economic relations with the Freestar Collective, which was broken in 2267 and restored in 2280.
The era of Owyn Lyons' reign was interrupted by the Brotherhood Civil War, between the Centralists (led by Jeremy Maxson) and the Reconstructionists (led by Owyn Lyons).
Since 2283, the Brotherhood of Steel faces their futures of uncertainty with the current reign of Supreme Elder Arthur Maxson.
The year 2289 saw the biggest events in the history of the Brotherhood of Steel; the United Colonies and the rest of Settled Systems mourns the death of former Supreme Elder Owyn Lyons.
By 2331, the Brotherhood of Steel would celebrate its 250 years of history, from the 2081 foundation and eventual current reign of Arthur Maxson.
The United Colonies remains the Brotherhood of Steel's largest political ally and their closest neighbor in the Settled Systems.

John Maxson-era (2155-2205)
By 2155, John Maxson ascends his throne and took his Oath of Ascension to become the 3rd Supreme Elder of the Broterhood of Steel and his reign played the central role in Fallout 1 (1997).
In 2162, things did really happened around the Settled System when the Brotherhood established its relations with the United Colonies, although the United Colonies gained independence from the Great Enclave in 2159.
The Brotherhood markes their historical moment of truth, as the United Colonies established their political and economic relations with both of them. Their 168-year diplomatic and military alliance with the Brotherhood and the United Colonies remains unbreakable to this day, throughout the Brotherhood of Steel's history as an absolute monarchy in the Settled Systems through the ruling House of Maxson.
John Maxson and the government of the United Colonies later helped to built Maxsonville, which in turn to be the capital city of Jemison Brotherhood, until 2230 relocation to New Citadel in the same planet of Jemison.

Owyn Lyons-era (2205-2231, 2235-2283)
In 2205, after the peaceful death of John Maxson at the age of 108, Owyn Lyons becoming the Supreme Elder under his regent, Elder Consort Elizabeth Lyons (2180-2278), until Lyons himself took his Oath of Ascension on February 6, 2218. 
In 2219, when he was 17 years old at the time of his reign, Owyn Lyons became the first Broterhood Supreme Elder to establish its relations with the Freestar Collective, in which broke off in 2267 due to Freestar's support of John Henry Eden's presidency of the Great Enclave.
By 2231, Sentinel Jeremy Maxson, a devoted follower of House Va'runn and the Great Serpent, proclaims his military coup and overthrows Owyn Lyons, and causing the political outrcy by the United Colonies and the Enclave.
In 2235, the Brotherhood of Steel restored Lyons as the Supreme Elder of the Brotherhood of Steel following his support of the United Colonies and the Enclave to topple Jeremy Maxson's regime.
In 2267, the Brotherhood broke off its diplomatic relations with the Great Enclave, due to the Great Enclave's support of John Henry Eden's plan to destroy the United Colonies, culminating the Brotherhood-Enclave War, and ended with the Brotherhood restored its relations with the Great Enclave in 2280 under the Great Enclave's then President Augustus Autumn, but the Brotherhood also re-established its relations with the Freestar Collective in the same year.
On January 14, 2283, after his 78-year reign, he abdicated his position as the Brotherhood Supreme Elder and his successor, Arthur Maxson, ascends his throne as the Supreme Elder of the Brotherhood and he did not taking his Oath of Ascension by November 9, 2283.

Jeremy Maxson-era (2231-2235)
In 2231, Jeremy Maxson overthrows Owyn Lyons as the Brotherhood's Supreme Elder in a coup d'etat backed by House Va'runn, thus culminating the Brotherhood Civil War, as Jeremy Maxson himself was aligned with the House Va'runn, despite Jeremy Maxson's ties with House Va'runn's religion of the Great Serpent deity. The Brotherhood Civil War broke out in 2232, between two Brotherhood of Steel factions, the United Colonies-backed Reconstructionists (led by Owyn Lyons) and House Va'runn-backed Centralists (led by Jeremy Maxson).
In 2235, The United Colonies and the Akila Enclave backed Lyons and his overthrow of Jeremy Maxson. After Jeremy Maxson's overthrow by Lyons, the Brotherhood of Steel restored Lyons as the Supreme Elder of the Brotherhood of Steel following his support of the United Colonies to topple Jeremy Maxson's regime.
In contrast, Jeremy Maxson's reign as a Supreme Elder was characterized by its hostile relations with the United Colonies with Jeremy's support from his religion of House Va'runn, prompting the United Colonies to support Owyn Lyons and his overthrow of Jeremy Maxson.

Arthur Maxson-era (2283-present)
In February 2283, just a month after the abdication of Owyn Lyons, Arthur Maxson took the position of Supreme Elder and marking the 10-month period of transition to the new era of the Brotherhood.
On November 9, 2283, at the age of 17, Arthur Maxson took his Oath of Ascension and the Brotherhood names him as the 6th Supreme Elder during his coronation ceremony in Starstation Cygnus (the capital and seat of the Supreme Elder of the Brotherhood).
In October 2289, the Brotherhood mourns the death of former Supreme Elder, Owyn Lyons, who died peacefully on his sleep at the age of 87.
In 2307, he broke off the Brotherhood's diplomatic relations with the Freestar Collective, House Va'runn, and the Great Enclave after the bombardment of New Atlantis by the Freestar military, leading to the Colony War.
By 2308, Supreme Elder Arthur Maxson supported the United Colonies and the Brotherhood deploys its volunteers to the planets of Niira, Jemison and Chawla, to repel the Freestar invasion of New Atlantis.
By 2310, Supreme Elder Arthur Maxson announced that the Brotherhood of Steel had restored its diplomatic relations with the House Va'runn, during the aftermath of a United Colonies-backed military coup that resulted in William Coulson's overthrow of the Great Enclave's totalitarian dictatorship under President Augustus Autumn (although Augustus Autumn himself was a highly devoted Great Serpent believer and supported the House Va'runn's alleged propaganda war against the United Colonies and the Brotherhood of Steel during the Colony War).
By 2312, the Brotherhood resumed its diplomatic relations with the Great Enclave, and the Freestar Collective following an "uneasy peace" after the Colony War's end. That year, the Brotherhood celebrated its 150th anniversary of its diplomatic relations with the United Colonies, with Arthur Maxson in attendance in New Atlantis during the event followed by Maxson's speech inside the MAST building.
Its unbroken 168-year relations with the United Colonies shaped the rich political history, diplomacy, military alliance, and economic development of the Brotherhood of Steel, and by 2330, Supreme Elder Arthur Maxson still leads the Brotherhood of Steel at the age of 63 on the peak of his power.

SUPREME ELDER
The Supreme Elder is a title used by the Brotherhood of Steel that acts as the leader/monarch of their monarchy within the Brotherhood. President Alexandra Abello of the United Colonies described the Brotherhood of Steel "as an absolute monarchy" with more fundamentally conservative religious, technological, and military ideals.
Each Supreme Elder uses His Majesty on informal purposes and many Supreme Elders played their significant role in the rich history of the Brotherhood.

List of Supreme Elders of the Brotherhood of Steel:
- Roger Maxson (2081-2135) (died 2135): Before he founded the Brotherhood of Steel in 2081, Maxson was a commander in the United States Army fighting against the Chinese Army during the Battle of Anchorage. Following the Great War of 2077, he founded the Brotherhood of Steel in 2081, a religious military hierarchy that was the only two absolute monarchies in the Settled Systems, the other one being House Va'runn. He was also being the main architect of Starstation Corvus, which was only completed in 2100 (1810 AD) to becoming the seat of the Supreme Elder. In 2100, the Brotherhood of Steel later elevated itself as a "monarchy" in the Settled Systems with the ruler/monarch of the Brotherhood holds the title of "Supreme Elder".
- Roger Maxson II (2135-2155) (died 2155): Roger Maxson II was the son of Roger Maxson, and he was being instrumental for the foundation of Starstation Corvus, the capital city of the Brotherhood of Steel between 2100 through 2170, when it was merged into Starstation Cygnus to became Great Starstation Cygnus under Supreme Elder John Maxson.
- John Maxson (2155-2205) (born 2097 - died 2205): John Maxson becomes the first Supreme Elder to establish its relations with the United Colonies in 2162 (1872 AD), thus over 168 years still unbreakable today. He was also being instrumental for the building of Starstation Cygnus (now Great Starstation Cygnus), which was the capital city of the Brotherhood of Steel in 2170 (1880 AD) and sits over the Alpha Centauri system. Until the Brotherhood established its relations with the United Colonies in 2162 (1872 AD), the Brotherhood maintains the Great Enclave as its diplomatic, trade, and political ally.

With his 78-year reign spanning from 2305 to 2283, Lyons was the longest reigning Supreme Elder of the Brotherhood of Steel and he is also the only Supreme Elder to not carry a surname of Maxson. As the first and only Supreme Elder to abdicate, Lyons died in 2289 at the age of 87, leaving his profound legacy.

His reign could triggered the Brotherhood Civil War, angering the United Colonies to support Owyn Lyons' leadership, as he argued that Jeremy Maxson was a follower of House Va'runn. In 2235, aided by the United Colonies, Lyons overthrew House Va'runn-aligned Supreme Elder Jeremy Maxson during the aftermath of the Brotherhood Civil War in Alpha Centauri system. Jeremy Maxson died in the same year when he was executed by the United Colonies for his war crimes against Owyn Lyons' reign.

Still reigning at the age of 63 in 2330, Maxson faces new challenges after the Colony War.

GREAT STARSTATION CYGNUS (THE BROTHERHOOD OF STEEL CAPITAL)
In 2082, a year after the Brotherhood of Steel was founded on Earth, the Brotherhood of Steel established Cygnus in the planet of Mars as its permanent capital city in the Settled Systems, until the Brotherhood decided to move its land capitals to Maxsonville in 2167, and finally New Citadel in 2230. Both Maxsonville and New Citadel were situated in Jemison.

Until 2100, Cygnus in Mars was the seat of the Supreme Elder, until the Brotherhood decided to move its Supreme Elder's seat to Starstation Corvus on the Alpha Centauri system in 2100 under the Supreme Eldership of Roger Maxson, before it was merged with Starstation Cygnus in 2170 to form "Great Starstation Cygnus".
After that, the Brotherhood still governs Cygnus as their only city in Mars.

UNITED COLONIES IN STARFIELD
Starfield, the newest title from Bethesda Game Studios, offers a new take in the Fallout series, following Bethesda's legacy in Fallout 3 and 4.
As the oldest known monarchy in the Settled Systems, the Brotherhood of Steel is an absoute monarchy in the Settled Systems, with the current Supreme Elder being Arthur Maxson.
The House Va'runn is a theocratic absolute monarchy that centered on the worship of the Great Serpent, with the monarch uses the title of Supreme Leader (a shortened version of Supreme Leader of the House Va'runn and the Great Serpent) and the current Supreme Leader is Anasko Va'runn.
The United Colonies (UC) is a Semi-Democratic and Meritocratic Federal Autocratic Presidential Republic republic in the Settled Systems, and controls the star systems Alpha Centauri, Sol, and Wolf. The UC's capital is the city of New Atlantis on planet Jemison in the Alpha Centauri system.
The phrace "Supra et Ultra", which was first coined by William Blackmore in 2161, is the official motto of the United Colonies and it has been recognized by fans of both Fallout series and Starfield. 
The current president of the UC is Alexandra Abello as of 2330, where Starfield takes place.

HISTORY OF THE UNITED COLONIES
The United Colonies was established in 2159 as a breakaway state of the Enclave, even during President Joseph Richardson's leadership with the Enclave. Just a year after the United Colonies gained their peaceful independence from the Enclave (now known as the Great Enclave), the colony of New Atlantis was founded in 2160, and officially became the United Colonies' capital in 2161.
In 2162, when the Brotherhood of Steel at their zenith in the Settled Systems, the UC officially established diplomatic relations with the Brotherhood under the Supreme Elder John Maxson's reign within the Brotherhood of Steel. The relations still unbreakable during the 168-year diplomatic history.
The UC attempted to expand into the independent system of Narion in 2194 by placing The Clinic star station above Deepala, but the residents of Narion protested and voted to join the Freestar Collective. The dispute over Narion escalated into the Narion War in 2196, which concluded in 2216 with the Treaty of Narion. The UC ceded its claim over Narion and recognized it as a Freestar member, and halted its expansion beyond the three star systems it already possessed.
In 2231, when the follower of House Va'runn and the Great Serpent's religion, Jeremy Maxson, staged a military coup with the Brotherhood of Steel against the Supreme Elder Owyn Lyons, leading the Brotherhood Civil War.
During the Brotherhood Civil War, the United Colonies and the Great Enclave supported the Reconstructionist faction, led by ousted Supreme Elder Owyn Lyons, while the Freestar and House Va'runn backs the Centralist faction (led by Jeremy Maxson).
By 2235, the United Colonies supports Owyn Lyons' overthrow of Jeremy Maxson, restoring Lyons as the Supreme Elder and ending the Brotherhood Civil War. That same year, the deposed Supreme Elder Jeremy Maxson was executed for his war crimes by the United Colonies Army by a firing squad.
By 2267, the United Colonies and the Brotherhood declares the war on the Great Enclave, angering Great Enclave's plan to destroy New Atlantis under the guidance of the Great Enclave president John Henry Eden.
In 2280, the UC restored its diplomatic relations with the Great Enclave and welcomed Augustus Autumn as the President of the Great Enclave. Throughout Augustus Autumn's presidency with the Great Encave, the UC played their important economic assistance to the Brotherhood of Steel alongside the Great Enclave.
Tensions between the UC and Freestar resurfaced in 2307, when the UC lodged a formal complaint over Freestar's colonization of the Lunara system and insisted that the Treaty of Narion prohibited Freestar from claiming a fourth star system. When diplomatic talks failed, the UC besieged the Freestar colony on the planet Vesta and killed all of its defenders, igniting the Colony War. This second conflict ended in 2311 after the UC Navy lost the Battle of Cheyenne to a Freestar flotilla of military and civilian ships, and both sides ratified the Armistice. In response to this defeat, the UC created the UC Vanguard, a civilian navy pledged to protect UC member colonies and interests, in 2315.
As of 2330, UC military forces are on alert due to increased aggression from the Crimson Fleet, which has established new footholds in several systems that threaten UC territory.

PRESIDENT OF THE UNITED COLONIES
The President of the United Colonies is the head of state and head of government within the United Colonies. The President also acts the commander-in-chief of the United Colonies Armed Forces.

UC CITIZENSHIP
Citizenship in the United Colonies (UC) is not automatic, and there are different grades. Residents of the UC can achieve citizenship through service by working for any of the branches of MAST, but the only option foreigners have to earn it is to enlist in the UC Vanguard, which is part of MAST's military branch. Citizenship benefits vary by grade and include credit rewards, the right to home ownership in New Atlantis, and discounts in UC businesses.
Earning citizenship is said to be difficult as MAST has limited employment slots. The administration and science branches of MAST are particularly competitive as they are more appealing to most people than the military. In order to make the military branch more appealing to applicants, the UC changed its policies so that citizenship could be earned substantially faster in the military than in the other two branches, and those who served in the military with distinction would be eligible for first-grade citizenship, the highest tier with the most benefits.
