American Brotherhood of Assassins

The American Assassins were the branch of Assassins located in and around the United States.
History
In 1503, a group of Italian Assassins traveled to Constantinople and infiltrated the shop of Piri Reis, an Ottoman admiral and cartographer. They obtained a map detailing the New World, and the Assassins started sending men there to ensure their presence to fight back against the Templars, who were also branching out to the Americas.[1]
In 1510, the Assassins in Florida welcomed the refugees Alonso Carlo and his adoptive son Miguel Ramón Carlo de Lugo, who had become enemies of the Templar-influenced Spanish explorer Juan Ponce de León.[2]
Miguel Ramón was taken into the Assassin Order, and was sent in 1521 to stop De León from continuing his search to find the Fountain of Youth. Miguel halted De León, though De León was struck with poisoned arrows fired by several Assassins when he did not heed Miguel's warning.[2]
The American Assassins also became heavily involved in the American Revolution in the later half of the 18th century.[3]
In 1865, after the American Civil War, the Assassins hunted down and killed John Wilkes Booth after he assassinated President Abraham Lincoln.[4]
