The Butlerian Jihad is a reference to samuel butler's 1872 proto-scifi satircal novel: https://en.wikipedia.org/wiki/Erewhon which talks about a society that had a machine intelligence uprising and so banned all complex machines.
This is literally spelled out in the page you are commenting upon. Didn't you read it first?
I did not. Erewhon is just one of my favorite books so when I see a thread about Dune I tend to talk about it. Normally I'd read the link but this was a generic "Fandom" wiki page and unlikely to be very useful to read.
Hint: do so in future.
This wasn't a normal 'article'. It was just a commercial wiki page on a well known topic. And a distasteful 'fandom' one at that. No information there was special or unique to it in particular. The real point was to have URL about the topic to start the conversation.
