acccording to author Alan Arnold, in 1979 “Margaret Thatcher … won the election and became Britain’s first woman prime minister. To celebrate their victory her party took a half page of advertising space in the London Evening News. This message, referring to the day of victory, was ‘May the Fourth Be With You, Maggie. Congratulations.’”
This resulted in a yearly fan tradition of calling May 4 “Star Wars Day” or “May the Fourth be With You Day,” in reference to the Jedi phrase used in the movies, “May the Force be with you.”
The phrase has been used in every Star Wars film since 1977 and has become a central part of the Star Wars universe. What few people realize is that when George Lucas penned these iconic words he was originally inspired by a similar phrase that has been used since the very beginning of Christianity.
