The Assassin's Creed, often referred to as the Creed, was the code and philosophy of the Assassin's Order upheld from at least the High Middle Ages until the modern era.

It restricted unnecessary slaughter of innocents, preserved the precious reputation of oneself and of the Order, and was meant to create peace, not only within the world, but within the individual.

Assassins hold battle weapons such as a dagger, a sword or their own made weapon.

The Assassins had been handing the Creed down orally from generation to generation, ensuring that its message was delivered to and upheld by every member of the Assassin Order. Al Mualim, one of the Mentors of the Order, once remarked that "We are nothing if we do not abide by the Assassin's Creed."

In the ancient Codex of Altaïr Ibn-La'Ahad, it was stated that the Creed cannot be killed, even if all of its followers were. He went on to explain that the Creed was an idea, and even if all records of it were destroyed, it could eventually be reinvented by another.

The goal of the Assassins was to ensure peace in all things. The Assassins believed that political assassinations and the death of the corrupt would bring peace and a true sense of security to the common people.

Slaying innocents and civilian bystanders who did not need to die could spread strife and discord, in addition to ruining the name of the Assassin Order itself.

Be unseen. The Assassins' aim was to get close to their target stealthily, and escape just as quickly. In more ancient times, Assassins aimed to perform ostentatious, awe-inspiring assassinations, usually in public.

The greatest illusion from such an assassination was that the Assassin seemingly materialized from nowhere, killed a corrupt public figure, and vanished into the depths of the crowd or environment. If an Assassin was spotted stalking their target, the supernatural effect would be diluted, and it became more difficult for the Assassin to reach his target.

The actions of one must never bring harm to all. If an Assassin failed in his or her duty, and was captured or chased, he or she must never commit any action or say anything that could be tied back to the Brotherhood, or bring harm to any member of it.

The three great ironies were observations that described the contradictions between the Creed, and the actions of the Assassins who followed it. They were:

The Assassins seek to promote peace, but commit Assassins seek to open the minds of men, but require obedience to Assassins seek to reveal the danger of blind faith, yet practice it themselves.

Though seemingly hypocritical, the ironies did not undermine the Assassins' cause. Rather, they demonstrated the way in which they embraced contradiction, "that one may be two things – opposite in every way – simultaneously."

Ezio Auditore da Firenze is the Mentor of the Italian Brotherhood of Assassins.

He is a example for a powerful and strong Assassin.
