Last September, Kira Kazantsev made Miss America history.

Standing on an Atlantic City stage in a white gown, the Hofstra grad became the third consecutive Miss New York to capture the national title. Never had one state won three years in a row — a trifecta that was all the more surprising given the state’s lack of a rich pageant tradition.

“It’s a piece of history that I get to be a part of,” says Kazantsev. “And we’ve all been the first of something!” In 2013, Mallory Hagan was the first Miss New York to take the crown since Vanessa Williams in 1983. And 2014 champ Nina Davuluri was the first-ever Indian-American to win.

“[New York] is one of the best places to be a state title holder because you get to do really cool stuff,” says Kazantsev.

Among her favorite duties? Attending a screening of the documentary “Private Violence” with Gloria Steinem.

So what are the odds that current Miss New York Jamie Lynn Macchia will keep the dynasty rolling at the Miss America Pageant on Sept. 13?

Her predecessors think she’s got a real shot — and are ready to share their winning advice with her.

Age:

26

Platform:

Child sexual abuse prevention

Talent:

Tap danced to James Brown’s “Get Up”

Hagan followed her reign with a move to LA, but after a year, “I decided it was time to use my scholarship dollars.”

Now, she’s living in Hell’s Kitchen and studying marketing at FIT. She started a company that works with pageant girls, teaching them to DIY their success.

“I had previously competed in Alabama, and it’s a well-oiled machine [there],” says Hagan. In New York, though, she had to make things happen herself — like bringing in shoe line Pink & Pepper as a sponsor.

She advises Macchia to tap into her New York resilience: “There’s a celebrity here on every corner, and you’re not necessarily the coolest person on the red carpet,” she says. Instead of worrying about that, “Stick to who you are.”

Age:

26

Platform:

Diversity through cultural competency

Talent:

“Bollywood fusion” dance

Davuluri is one of the busiest retired Miss America champs ever, traveling three weeks each month to promote her diversity campaign, Circles of Unity.

Born in Syracuse and a graduate of the University of Michigan, she says she started doing pageants for scholarship money and has earned more than $95,000 for schooling, which she plans on continuing — with the ultimate goal of becoming an ambassador to India.

Fittingly, Davuluri’s advice for Macchia is to think about the big-picture future. “Present yourself as you want to be remembered,” she says.

The Upper East Sider doesn’t just travel for business: She recently vacationed in Cabo with the former Miss Virginia, Miss Arkansas and Miss Illinois.

Age:

24

Platform:

Domestic violence awareness

Talent:

Sang Pharrell Williams’ “Happy” and performed percussion using a red Solo cup — a la Anna Kendrick in “Pitch Perfect”

This pretty brainiac — formerly a hostess at the Flatiron restaurant Harding’s — earned a scholarship to Notre Dame but deferred to fulfill her Miss America duties.

And don’t expect Kazantsev — who is first-generation American, born to Russian parents — to trade in her crown for a briefcase anytime soon. After she hands down the sash next weekend, she’s heading to Los Angeles to pursue a career in the entertainment industry, though she’s still unsure just what she wants to do.

“For the first time in my life, I don’t have an exact plan,” she says.

Kazantsev was motivated to explore a glossier occupation during her hectic year of Miss America travel that took her from Afghanistan on a USO tour to introducing Pitbull at the American Music Awards.

“That [reigning] year teaches you how to network and get yourself in the door. It’s a course in life.”

No surprise, then, her advice for Macchia is to be open to change and to take whatever comes. “If it works out, wonderful. If it doesn’t, life has another plan for you. There are so many successful women who have come from the organization, whether they were Miss America or not.”

As for herself, the reigning national queen and Manhattan resident is ready to reclaim the simpler things in life. “I love waking up in the morning and introducing myself as Miss America. But I’m excited to be Kira again.”

Jamie Lynn Macchia, Miss New York 2015

Age:

23

Platform:

Raising money for pediatric cancer research

Talent:

Lyrical dance to Beyoncé’s “I Was Here”

With a boyfriend in the FDNY, an outer-borough accent and a weakness for pizza at Lee’s Tavern in Staten Island, Macchia is Big Apple to the core.

“You have to work hard to get what you want in New York,” says Macchia, who graduated from Wagner College. “I’ve had people say to my face that they don’t want New York to win [Miss America again]!”

Not that she’s listening. Macchia’s goal is to spread awareness of the need for pediatric cancer research.

“My best friend passed away from leukemia when we were 15. Only 4 percent of government funding for cancer research goes to childhood cancer,” she says.

Regardless of the outcome next week, her calendar is already packed.

“If I don’t win, I will be Miss New York until next June.”
