Following the 22-year-old's sensational US Open victory at Congressional, which came a year after compatriot Graeme McDowell secured the same trophy at Pebble Beach, the young golfer from Holywood, Belfast was asked what he thought the secret to his country's recent success was.
Speaking to Sky Sports, he said: "I don't think a European had won it in 40 years until Graeme and then the two of us win it back to back.
"I'm not sure what it is, obviously Graeme and myself are both good players and growing up in tough conditions - like a US Open usually is - probably helped, but I don't think you can explain having two US Open winners back to back with a population of one and a half million."
The player also thanked his parents for all the support he received over the years, adding: "They've been the best parents in the world and this is just a little token of appreciation for everything they've done for me."
McIlroy will now turn his attentions to next month's British Open where he will be looking to claim his second major.
