Butlerian Jihad

The Butlerian Jihad is a pivotal event in the Dune universe, a conflict between humans and artificial intelligences that occurred thousands of years before the events of the series. The AI, which had become a threat to human existence, was defeated through a combination of bravery and technological innovation. The war led to the creation of the Great Scattering, where humans fled their home planet of Earth to colonize other planets and avoid the possibility of AI resurgence. This event had a profound impact on the Dune universe, influencing its politics, culture, and technology.
