Yes, Jediism is a real thing. It was invented around 2001 by fans of the “Star Wars” series after a number of people listed their religion as “Jedi” on the national census. The movement started out as a joke, but many fans view it as a new age religion following the moral code of conduct followed by fictional Jedis.
Jediism sets aside the sci-fi elements of the series and focuses on mindfulness and other Jedi teachings. As silly as it sounds, some people take it seriously. A Temple of the Jedi Order was even registered in Texas in 2005.
A religious movement followed by thousands of Star Wars fans all over the world, Jediism (or the Jedi Church) is a new religion that incorporates the fictional teachings of the Jedi. They believe that The Force is a very real power in the universe. In 2013, Jediism was actually the seventh largest religion in the UK with an incredible 175,000 followers.
