- This article is about the Assassin. You may be looking for the Persian king.
Darius was the assassin of King Xerxes I of Persia. A proponent of free will, he is considered to be one of the very first proto-Assassins, active several centuries before the order's formal establishment. His assassination of the Persian king was the first recorded usage of the Hidden Blade, which went on to become the iconic weapon of the Assassin Brotherhood.
During the 5th century BCE, the precursors to the Templars supported the reign and conquests of the Achaemenid kings Darius I and his son Xerxes I. Opposing the Persian kings' tyranny over the people, Darius personally assassinated King Xerxes I with the Hidden Blade in August 465 BCE, in what would become the first recorded use of the Assassins' iconic weapon.
By 48 BCE, his Hidden Blade wound up in the hands of Queen Cleopatra of Egypt, who passed it on to her protector Aya. After she made her own, Aya in turn gave Darius' blade to her husband Bayek. After the two founded the Hidden Ones, it became the iconic weapon of their organization, still used centuries later when their Brotherhood reformed as the Assassins.
By the Renaissance, a tomb dedicated to Darius was located in the Basilica di Santa Maria Novella in Florence, where a sarcophagus lay with an Assassin Seal that provided access to the hidden armor of Altaïr Ibn-La'Ahad. In 1478, this sarcophagus was opened by Ezio Auditore, who took the Seal and later obtained the armor.
- Unlike most Assassins, Darius wore his Hidden Blade on the right arm.
- Historically, Xerxes was assassinated by Artabanus, who according to Aristotle had murdered the Crown Prince of Persia Darius just prior to the deed. The Latin historian Justinus however offers an alternative account where Crown Prince Darius was executed for the patricide of Xerxes after being framed by Artabanus. The relation between the Darius of Assassin's Creed and that of Crown Prince Darius is unknown.
