The next time you buy a history book, make sure to look up the name AJ Styles ... because The Phenomenal One says he'll be included after winning the WWE Championship at Backlash.

In case you missed it, Styles beat Dean Ambrose to win the title -- his first championship in WWE -- and he did it less than a year after making his debut in the company at the Royal Rumble.

For those keeping track at home ... this means Styles has now won the TNA World Heavyweight Championship, the IWGP Heavyweight Championship and the WWE Championship throughout his career -- which means he's definitely telling the truth by saying he's made it into the history books.

Following the victory, AJ was asked about his less-than-clean way of winning the match and the new champ had no reservations about how he got the job done. Check it out below.
