Assisting Alexander the Great
In the 4th century BCE, The Templars allied themselves with Macedonian King Alexander the Great. As a symbol of their alliance, the Templars entrusted Alexander with a Staff of Eden, which helped Alexander to create one of the largest empires in history and become one of the most successful military commanders. However, on 13 June 323 BCE, Alexander was poisoned inside the palace of Nebuchadnezzar II by the Babylonian Assassin Iltani, who then retrieved the Staff. After Alexander's death, his empire soon began to crumble.
In 1511, the Templars leaders in Athens paid Ottoman soldiers handsomely for looted goods. In response, Assassin Mentor Ezio Auditore sent some Assassins from Constantinople to Athens in order to eliminate them.
Seven Years' War
During the Seven Years' War, Shay Cormac sent some agents of his fleet to the island of Crete, which had been used by the Templar Order as a headquarters many times across the centuries, to depart for nearby kingdoms. They recovered a Cretan Mosaic of the Minoan Civilization.
