Non Est Deus was founded in September 2017 in Bamberg, Bavaria. The project was created as a black metal solo project by "Noise", who was already the head of the black metal band Kanonenfieber. The songs mainly revolve around topics such as blasphemy and anti-Christianity. The Last Supper, Non Est Deus' debut album, was released in 2018. Further albums followed with There Is No God (2019), Impious (2022) and Legacy (2023).
In 2026, Non Est Deus released another album, Blessings and Curses.
