What was the name of the 1985 wrestling event that launched the WrestleMania series?

WrestleMania I was the 1985 event that launched WWE’s WrestleMania series.

The show took place on March 31, 1985, at Madison Square Garden in New York City. Its main event featured Hulk Hogan and Mr. T against Roddy Piper and Paul Orndorff, with Jimmy Snuka and Bob Orton Jr. accompanying the opposing sides. Hogan’s team won the match.

WWE promoted the event as a major entertainment spectacle, combining wrestling with celebrity appearances and a live closed-circuit broadcast shown in cinemas and arenas across North America. Celebrities included Cyndi Lauper, Liberace, and Muhammad Ali, who served as a special guest referee.

The event was originally billed simply as WrestleMania; the Roman numeral “I” was applied retrospectively as the series continued. The next installment was WrestleMania 2, held in three arenas on the same night in 1986.
