Barack and Michelle Obama have been married for 31 years. Here's a timeline of their relationship.

Barack Obama, then 28, and Michelle Robinson, then 25, met at the Chicago office of the law firm Sidley Austin LLP, where Robinson was assigned to be his mentor.

"Because I went to Harvard and he went to Harvard, and the firm thought, 'Oh, we'll hook these two people up,'" Michelle told ABC News in 2008.

In his 2020 memoir, "A Promised Land," Barack Obama wrote he "was smitten almost from the second I saw her."

Though she was his mentor, that didn't stop the future president from asking Robinson on a date. She said she was not so keen at the time.

"Barack, about a month in, asked me out, and I thought 'No way. This is completely tacky,'" she told ABC News in 2008.

But eventually she relented, and the pair went on a date. They started by having lunch at the Art Institute of Chicago, taking a stroll, then ending up going to see the Spike Lee film "Do The Right Thing."

"He showed all the sides — he was hip, cutting edge, cultural, sensitive. The fountain — nice touch. The walk — patient," Michelle Obama told The Telegraph in 2012.

"Take tips, gentlemen," Barack Obama added, smiling.

The date was eventually immortalized in the 2016 film "Southside With You."

The pair got engaged at Gordon's restaurant in Chicago. The dinner was supposed to celebrate Barack Obama passing his bar exam, they told ABC News.

"And then the waiter came over with the dessert and a tray. And there was the ring," Michelle Obama said. "And I was completely shocked."

She told ABC News that he simply got down on one knee and asked. She, of course, said yes.

The couple married on October 3, 1992. Michelle later noted that her husband's vows were a glimpse at what was to come.

"Barack didn't pledge riches, only a life that would be interesting. On that promise he delivered," she recalled, according to the Obama Foundation website.

After the ceremony, their reception was held at the South Shore Cultural Center and they honeymooned along the California coast, Brides magazine reported.

Malia was born on July 4, 1998.

Natasha, known as Sasha, was born on July 10, 2001.

Barack Obama said in a 2013 interview that he thinks that he and Michelle's love has been a great example to their daughters.

"The great thing about the girls is they've got a wonderful role model in their mom," Obama told Essence. "They've seen how Michelle and I interact — not only the love but also the respect that I show to their mom. So I think they have pretty high expectations about how relationships should be, and that gives me some confidence about the future. I joke about this stuff sometimes, but the truth is they are smart, steady young women."

Though he was a state senator for several years, Obama became the US senator for Illinois in 2004, catapulting the family into the national spotlight.

Michelle Obama was a notable figure on his campaign, but she had her own impressive role as vice president for Community and External Affairs at the University of Chicago Hospitals, according to the hospital's official website.

Though he had a notable term, he once joked that being Michelle's husband was what people loved most about him.

"If you were going to list the 100 most popular things that I have done as president, being married to Michelle Obama is No. 1," he said during a State of the Union address in 2010.

Obama won a re-election bid against Mitt Romney in the 2012 presidential election. By then, the couple was a household name, with Michelle being known for her healthy-eating initiatives. The president noted that he couldn't have done nearly as much in his time in office without the support and guidance of his wife.

"Obviously I couldn't have done anything that I've done without Michelle," he told Oprah Winfrey on "The Oprah Winfrey Show" in 2011. "Not only has she been a great first lady, she is just my rock. I count on her in so many ways every single day."

Both Barack and Michelle Obama made clear that although they enjoyed their time in the White House, they were ready for a bit of normalcy after eight years.

"I want to open my front door without discussing it with anyone — and just walk," Michelle told Oprah Winfrey at the United State of Women summit in 2016, People magazine reported.

"I want to go to Target again! I've heard so many things have changed in Target! I tell my friends they're going to have to give me a re-entry training for like, 'OK, what do you do at CVS now? How do you check out?'" she joked.

"All the women in my life are looking forward to being able to live a more normal life," Barack also told Jimmy Kimmel on "Jimmy Kimmel Live!" that year.

Once they left office in January 2017, the Obamas took some time off. They traveled to Italy, Hawaii, and Necker Island in the British Virgin Islands, a spot owned by billionaire Sir Richard Branson.

The political powerhouses celebrated 25 years together on October 3, 2017.

"Happy 25th anniversary @barackobama. A quarter of a century later, you're still my best friend & the most extraordinary man I know. I <3 you," Michelle wrote on X, formerly known as Twitter.

While talking about her time in the White House with Valerie Jarrett, Barack emerged from backstage with a bouquet of pink roses.

"You don't get this at every show!" Michelle told the audience.

"This is like — you know when Jay-Z comes out during the Beyoncé concert? … Like, Crazy in Love?" Barack said. "It's the same thing. It's just a little sample to enhance the concert."

Barack dedicated his book to "Michelle — my love and life's partner, and Malia and Sasha — whose dazzling light makes everything brighter."

In "A Promised Land," he wrote about his courtship with Michelle and the early days of their relationship, as well as her initial opposition to his political ambitions.

"She was tall, beautiful, funny, outgoing, generous, and wickedly smart — and I was smitten almost from the second I saw her," he wrote.

Michelle wore a plum monochrome look comprised of pants, a sweater, belt, and jacket that were all created by American designer Sergio Hudson.

Barack Obama said that Michelle's portrait by Sharon Sprung captures everything he loves about her: "Her grace, her intelligence, and the fact that she is fine."

The former president's portrait was painted by Robert McCurdy.

On the Revolt x Michelle Obama special hosted by Angie Martinez and featuring panelists Tina Lawson, Kelly Rowland, H.E.R., and Winnie Harlow, Michelle said she was often frustrated with her husband when their daughters were young, Insider's Anna Medaris reported.

She said the tension between them stemmed from "measuring" tasks, like how many diapers each changed, until she realized that "marriage isn't 50/50, ever."

The former first lady added that it's important to "know your person" in order to get through those rough patches.

"Do you like him? I mean, you could be mad at him, but do you still look at him and go, 'I'm not happy with you, but I respect you. I don't agree with you, but you're still a kind, smart person,'" she said.

On an April 25 episode of Michelle's Audible podcast series "The Light Podcast" featuring conversations from "The Light We Carry" book-tour events, Winfrey asked the former first lady about how she and Barack navigate their relationship differently.

Michelle said that her husband is more verbally and physically affectionate because he and his family lived far apart and didn't get to see each other very often, whereas she grew up surrounded by extended family and views expressing love as being present.

"I grew up with everybody within eight blocks of each other," she said. "All my aunts, and uncles, and great uncles, and cousins, and everybody celebrated birthdays. So we were with each other, every weekend, twice a weekend. We were always together. So it was like, 'Mmm, bye. I don't have to tell you I love you because I'm going to see you Saturday.' So love, for me, was showing up. It was like, 'Yeah, yeah. Stop kissing me. Just do the laundry.'"
