The 22-year-old added a centimetre to the previous record he had set in Glasgow in February 2020.

Duplantis had already secured the victory at the Belgrade Indoor Meeting, a World Athletics Indoor Tour silver event, at the Štark Arena before he made the record-breaking leap on his third attempt.

He nudged the bar with his knee slightly but nevertheless cleared it before jumping off the mat and pumping his fists in celebration.

"A height like 6.19 - it demands perfection," said Duplantis.

"All the numbers have to be right.

"So, I just figured it out on that last attempt, and I was able to get over it finally."

Duplantis had tried unsuccessfully jumping 6.19m after winning the Olympic gold at Tokyo last year.

At an indoor meeting in Berlin last month, German organisers actually set the pyrotechnics off because they thought that Duplantis had broken the world record, only for him to knock the bar off on his way down.

"I think I’ve tried 6.19m 50 times," Duplantis said.

"It’s been a long time coming.

"I’ve never had a height that has given me that much trouble and I’ve been jumping for a very long time.

"It’s a very good feeling because it’s been really hard-fought over these past two years to try and get over that next barrier."

Duplantis hinted that he believes he can improve the record when the Serbian capital hosts the World Athletics Indoor Championships, which are due to start on March 17. 

"I don’t think this is the highest that I’m ever going to jump," Duplantis said.

"There’s going to be a lot more to come.

"This [Belgrade] is a really good place to jump for championships and I’m going to try and put something else higher up there."

Only 14 men have cleared 6.00m indoors and Duplantis has now recorded heights of 6.17m, 6.18m and 6.19m - the three best performances in history.
