Ubisoft developed and published the Assassin's Creed video game series.
Ubisoft Montreal developed the original Assassin's Creed, while Ubisoft's publishing organization released it in 2007. As the franchise expanded, other Ubisoft studios contributed to individual games, including Ubisoft Quebec, Ubisoft Singapore, Ubisoft Sofia, and Ubisoft Annecy.
The series is owned by Ubisoft and is one of the company's major intellectual properties. Its games have been released across home consoles, handheld systems, personal computers, and cloud-connected platforms. The franchise has also expanded into novels, comics, a feature film, and other media.
People sometimes name Ubisoft Montreal as the publisher because that studio created the first game, but the broader company is Ubisoft. Likewise, the historical characters and settings come from the games' fiction and research; they do not indicate that the series was produced by a historical institution or a studio from the countries depicted.
