First Barons' WarEdit
The earliest known actions of the British Branch was its support of the French-supported baronial uprising against the King during the First Barons' War from 1215 to 1217. Led by Robert Fitzwalter, the Assassins were determined to end the despotic rule of King John, who they knew was nothing but a pawn of his Templar advisors.
However, the Master Assassin William of Cassingham, operating independently from the Brotherhood, led a guerrilla force supporting the King, firstly because he refused to side with the French but mainly because he was a staunch supporter of John's son, Prince Henry.
Contact with the Caribbean branchEdit
The Order still existed in the early 18th Century and had a Mentor within the ranks as well as various other senior members. Around 1700, an Assassin sailor introduced Duncan Walpole into the Brotherhood. Duncan eventually became a Master Assassin, though his immoderate temper and arrogance was seen as a liability to most of the Order. This lack of loyalty led to Duncan defecting to the Templar cause and began corresponding with Laureano de Torres y Ayala.
In 1714, Duncan was tasked with meeting Ah Tabai, Mentor of the Caribbean Brotherhood. After learning the locations of the Assassins' headquarters in the West Indies, Duncan sailed aboard HMS Intrigue, with the hope of joining the Templar Order. His plan began to unravel after HMS Intrigue attacked the Jacobite, shipwrecking Duncan and a pirate named Edward Kenway, who ultimately killed Duncan at Cape Bonavista.
In 1722, Edward, who had become affiliated with the Caribbean Assassins, eventually joined the British Brotherhood after sailing to London. He quickly ascended to the rank of Master Assassin and, alongside Miko, effectively became a co-leader of the branch. Together, the two managed to bring great stability to the Brotherhood, creating vast connections throughout London ranging from the noble high society to the criminal underworld. This further expanded their forces and presence and thus managed to diminish the Templar threat in the country. Outside of London, Miko began searching all over Europe for the Pieces of Eden whilst making connections and providing his aid to the various regional branches.
Over the following years, Edward continued his research, utilizing his commercial activities to locate First Civilization sites across the globe; he discovered numerous Temples located in Italy and Alamut, as well as the hidden library of Altaïr Ibn-La'Ahad at Masyaf. Additionally, Kenway attempted to discover the location of the Grand Temple and thus recorded his research into his personal journal.
At some point during his travels, Edward discovered the Shroud of Eden, a powerful Precursor artifact capable of healing fatal injuries. Upon learning of its power, Edward elected to keep the artifact hidden and thus concealed the artifact in a case constructed by the First Civilization which would be accessible only to a key of the same design. In order to ensure its secrecy, Edward stored the artifact underneath the Tower of London and placed the key within a secret room above the dome of St. Paul's Cathedral.
Additionally, Edward donated his ship, the Jackdaw, to the Brotherhood, expanding their forces out to the open sea. He kept the vessel's wheel for a hidden compartment in his manor which inside held a Precursor artifact designed to open the dome of St. Paul's Cathedral, as well as the detailed history of the London Assassins. Edward raised his son Haytham to become an Assassin from an early age.
In 1723, Edward became acquainted with Reginald Birch who, unbeknownst to him, was a member of the British Rite of the Templar Order. Birch planned to acquire Edward's journal, with a view to locating the Grand Temple himself. Birch succeeded in this endeavor in 1735, when a group of mercenaries hired by Birch killed Edward and obtained his journal.
Struggling against the TemplarsEdit
During the mid-18th century, the British Brotherhood was at a disadvantage with their limited manpower and resources, and struggled to combat against their Templar counterparts.  After the death of Kenway, Miko attempted to lead the Brotherhood to his best efforts. At some point Miko became acquainted with Achilles Davenport, Mentor of the newly established Colonial Brotherhood. In 1751, Miko informed him that Reginald Birch had begun searching the world for various Pieces of Eden that would defiantly aid the British Templars in their search for the Grand Temple. More importantly, they feared that Birch would send his deadliest agent, Haytham Kenway, to the colonies. With this message, Miko was sent on an assignment in Corsica, but not before promising to contact Achilles as soon as possible.
By 1753, Miko had arrived in Corsica and was assigned to protect Lucio Albertine, a codebreaker and ally to the Order. However, with Corsica in the midst of a revolution, the two resided in an encampment along with several rebels fighting for independence against Genoa. One June night, their camp was attacked; while Miko fought against the Genoese soldiers, Lucio attempted to escape, only to be kidnapped by Haytham Kenway. With haste, Miko caught up and engaged Kenway in battle. Despite a valiant attempt, Haytham managed to fend Miko off. After climbing a rope, Miko was forced to end his pursuit of the Templar, for fear of falling to his death. Before he ended the chase, Miko promised Haytham that the two would encounter each other again, but only one would survive.
At some point after returning to London, Miko was entrusted with the Grand Temple Key. In 1754, Miko, accompanied by his nephew, attended a performance of The Beggar's Opera in the Theatre Royal. During the play, Haytham navigated through the theatre and assassinated Miko, taking possession of the key.
Following Miko's death, the Brotherhood tasked Louis Mills with pursuing Haytham and eliminating him. To execute his plan, Mills boarded the Providence posing as one of its crew members, and secretly threw marked cargo overboard each night, leaving a trail for the Assassin vessel, the Aquila, to pursue the Providence.
The plan failed, however, as Haytham managed to kill Louis in a duel. Shortly after, the Aquila appeared in pursuit of the Providence, lured by Mills' trail of cargo. Haytham persuaded Samuel Smythe, the captain of the Providence, to sail through a brewing storm in order to lose the pursuers. During the storm, the Aquila was heavily damaged and forced to abandon the pursuit. Following this, the London Brotherhood began to largely diminish in numbers until their presence was almost completely eradicated from London by the growing British Templars who managed to seize control of the country, and began to serve as a centuries-long decline of the Assassin Order.
During the 19th century, the British Brotherhood was led by an Assassin Council, forming a more structured and ordered branch that attempted to solve matters in a more methodical approach. Ethan Frye joined the Brotherhood alongside his wife Cecily; the pair became high ranking members who undertook missions for the Brotherhood operating in Crawley. Some point later, Ethan rescued a local mill worker, George Westhouse, from robbers near a riverbank. Grateful for his aid, George subsequently joined the Brotherhood with Ethan and Cecily acting as his mentors, tutoring him in methods of the Assassins.
Henry Green was assigned as the leader of the weakened Assassins stationed in London where he became acquainted with George Westhouse. During this time, Henry was able to make several connections throughout London, gaining resourceful information and considerable allies. Among his allies were Alexander Graham Bell, an inventor whose ingenuity aided the Brotherhood and Frederick Abberline, Chief Inspector of the London Metropolitan Police Service whose aid became beneficial for keeping the Assassins' activities secret from the populace.
The Templars were led by Crawford Starrick, who held a stranglehold on London's industry, gangs, boroughs and social classes. Green petitioned the Council for aid but was declined, as the Council felt that Starrick's empire was too powerful to defeat, and any Assassin who felt otherwise were encouraged not to intervene. In 1868, the twins Jacob and Evie Frye, who were born into the Brotherhood, decided to defy the Council and moved to London. While there, the two worked to eliminate the oppressive Templar presence. Jacob created a gang called the Rooks to combat the Templar-controlled Blighters.
However, the Frye twins had diverging goals; Jacob simply wanted to kill Templars, neglecting that their deaths would affect the citizenry, whereas Evie focused all her efforts on locating the Shroud of Eden. Ultimately, the twins agreed to work together one last time to stop Starrick from killing the ruling class of London and obtaining the Shroud. Following Starrick's death, the Fryes reconciled their difference and agreed to continue working together.
With the defeat of the Templars, the British Brotherhood began to recover and rebuild their ranks. Evie later married Henry Green and moved with him to India subseqently joining the Indian Brotherhood. Jacob remained behind in London to strengthen the Assassin's presence and thus recruited several initiates into the brotherhood, among them was a young apprentice named 'Jack the Lad' whom Jacob liberated from Lambeth Asylum and was described as 'reckless and roguish'.
Around 1870, Jacob travelled to India visiting his sister and brother-in-law Henry alongside Jack as well as several of his new initates in order to train in the fear tactics of the Indian brethren.
Autumn of TerrorEdit
In 1888, one of Jacob's apprentices, known only by the name Jack, developed an extremist view of the Assassins' mission. Eventually, Jack usurped control of the Rooks from Jacob and killed anyone sent to deter him. Radicalizing his followers, Whitechapel, the center of Jack's operations, descended into a cesspool of crime and depravity. Jacob sent Assassins disguised as prostitutes after Jack, all of which were brutally killed at the hands of Jack, who thereafter began to go by the pseudonym "Jack the Ripper". Jacob was later captured by Jack, but not before the Master Assassin sent a letter summoning Evie back to London. Evie later go on to assassinate Jack's underlings before tracking him down and put an end to the Ripper, saving Jacob in the process. To avoid public exposure of the Brotherhood, Evie requested Inspector Frederick Abberline to cover up the Ripper's death.
World War I Edit
Many British assassins such as Sam Crowder and an assassin medic, enlisted in the army during the war. On the Christmas truce of 1914, the assassin medic treated wounded British soldiers while German artillery hit the British trenches. As the British and German troops fraternized, the medic assisted the German general and member of the Templar Order, Erich Albert, with saving the life of a wounded German soldier. Following this, Albert showed his ring to the medic. In return, the medic revealed the Assassin brand on his finger, and killed Albert with his Hidden Blade before the Templar could react. In 1916, at the behest of Winston Churchill, the assassin Lydia Frye, Jacob Frye's granddaughter, eliminated a German spy ring operating around Tower Bridge. The spy ring was led by a Templar Master Spy, who was killed by Lydia. In exchange for her services, Churchill promised Lydia that he would do what he could for the enfranchisement of women when he had returned to parliament after the War.
Spanish Civil WarEdit
In 1936, the British Brotherhood sent Nobby Clarke to eliminate an entire Templar branch in Tallinn, the mission was a success. During the Spanish Civil War Ignacio requested the Brotherhood to sent at least a dozen assassins as back up but they only sent Nobby.
During the 18th century, the two co-leaders Edward Kenway and Miko were known to utilize Hidden Blades, swords, pistol alongside the cane-sword which over the following years became a significant weapon for the British Brotherhood due to the weapon's concealed usage and efficiently which was passed down through the following centuries.
During the 19th century, the standard Hidden Blade acquired two new insertions. These included a rope launcher and the ability to fire hallucinogenic darts; firing a dart into an open flame would result in a poisonous gas cloud, allowing the Assassin to eliminate multiple enemies from a distance.
