In 2014, Harry launched the multi-sport event created specifically for wounded, injured, or sick armed services personnel.
The title comes from the Latin word Invictus, meaning unconquered or undefeated.
“These guys do not want sympathy,” Harry told PEOPLE exclusively in 2016. “They view it as an opportunity to put on a show for all those people who have supported them.”
The games are similar to the U.S. Warrior Games, which was created in 2010 by the United States Department of Defense. Harry says he was inspired to create his own event after seeing a British team compete in the Warrior Games in 2013.
The first Invictus Games took place at London’s Queen Elizabeth Olympic Park after just 10 months of planning. Over 300 competitors (including U.S. military members) from over 13 countries joined in the fun.
More than 500 competitors from 15 countries competed in the second annual Invictus Games in Orlando, Florida in 2016. There, there were 10 sporting events, such as wheelchair basketball, swimming and indoor rowing.

This year’s games kick off Saturday evening, officially starting eight days of sporting events across 12 adaptive sports involving around 550 competitors from 17 nations. It ends on September 30 with a star-studded concert with performances by Bruce Springsteen, Kelly Clarkson and Bryan Adams.
Harry’s girlfriend, Meghan Markle, is expected to attend the games in her adopted hometown of Toronto (where she films her hit show, Suits), according to insiders, but she is likely to do so in an unofficial capacity — cheering from the stands.
The fourth annual Invictus Games are set next year in Sydney, Australia.
