Piracy is an act of robbery or criminal violence, typically at sea, and can also range to naval warfare and coastal raids. Acts of piracy can be committed on land, in the air, or in other bodies of water including shores.
In the early 18th century, a large number of pirates, privateers, and other sailors congregated in the recently captured settlement of Nassau and together formed the Brethren of the Coast, in order to better represent and coordinate their interests.
Pirates sailed the Mediterranean Sea during the Middle Ages, including a group of Cypriot pirates who allied with the Templars controlling Cyprus. During Altaïr Ibn-La'Ahad's trip to Cyprus in 1191, a pirate named Pasha sailed him to Kyrenia. However, the majority of the pirates there attempted to capture him for the Templars. When Altaïr returned to Limassol, he assassinated their captain.
In 1511, Al-Scarab was an honorable pirate who sought revenge on Ezio Auditore da Firenze for humiliating him, but after they worked together to fight off some watchmen, he returned the favor by sailing him to Acre. Soon after, the Ottoman Assassins allied with the corsair Hayreddin Barbarossa to undermine Spanish control of Algiers. Also active at the time was the Templar pirate Eveline Guerra, and Blaise Legros, whose only loyalty was to money, transporting Templars and Assassins wherever they desired so long as they could pay him.
The Golden Age of Piracy was considered to have taken place from the late 17th century to the early 18th century in the Caribbean Sea. The French pirate François l'Olonnais was active in the Caribbean Sea during the late 17th century. He was infamous for his cruelty, torturing his prisoners.
During this time, William Kidd was a Scottish privateer active in the area. He was captured and executed on charges of piracy in 1701, but in truth, the accusations were made by Templars, hoping he would reveal the location of the Shard of Eden he had found.
Alonzo Batilla and Olivier Levasseur were French privateers-turned-pirates operating in the Caribbean during the early 18th century. Levasseur, better known as La Buse, would later be executed by the British.
Edward Kenway was a British privateer-turned-pirate active in the Caribbean, who joined the Assassins later into his life. In the pirate republic of Nassau, there were pirates such as Stede Bonnet, Mary Read, Edward Thatch, Benjamin Hornigold, John Cockram, Josiah Burgess, Charles Vane, Jack Rackham, Adéwalé, Anne Bonny, and Christopher Condent, with many of them eventually banding together to form a coalition they referred to as "the Brethren of the Coast". By September 1715, almost five hundred men had joined the Brethren. However their capital, Nassau, fell to the British in 1718, quickly discouraging many members from staying. Most of the captains who had formed the group died over the years, leading to the Brethren's dissolution by 1722.
During the mid 18th century, the pirates Joseph Reed and William Crest made a fortune attacking trade ships in the Atlantic Ocean. However, their Men O' War, the Pilgrim and the Cauldron, were eventually sunk by Shay Cormac's ship, the Morrigan.
