In his final address to the nation, US president Barack Obama returned to the city where he says it all began - Chicago, his adopted hometown.
It's where he claimed victory in 2008 and 2012, and it's where the 44th US President spoke to the nation with what he said was not just a farewell, but a thank you.
He also gave a touching tribute to his wife Michelle, thanking for her for her work in the past eight years and saying she has been an incredible role model for children across the country.
"For the past 25 years you have not only been my wife and mother of my children, but you have been my best friend," he said.
"You took on a role you didn't ask for and you made it your own with grace, and with grit, and with style, and good humour.
"You have made me proud and you have made the country proud."
Mr Obama also praised his two daughters, Malia and Sacha, who had to grow up in the spotlight, saying: "Of all that I've done in my life, I am most proud to be your dad".
Thousands of supporters and staffers packed the room for Mr Obama's speech, where he talked about everything he had achieved in his time as president.
"If I told you all that, you might've said our sights were set a little too high. But that's what we did. That's what you did. You were the change," he said.
He asked citizens to unite behind president-elect Donald Trump, who will be sworn in on January 20, stressing the importance of democracy in the country.
"…We're all in this together. We rise and fall as one," Mr Obama said.
"I committed to president-elect Trump that my administration would ensure smoothest possible transition, just as president Bush did for me. Because it's up to all of us to make sure our government can help us meet the many challenges we still face."
It was the only time in the speech Mr Obama mentioned his successor by name.
Mr Obama said democracy is threatened when people take it for granted and called for people to take action, rather than sit back or argue.
"If you're tired with arguing with strangers on the internet, try talking to one of them in real life," he said.
"If something needs fixing, then lace up your shoes and do some organising. If you're disappointed by your elected officials then get a clipboard, get some signatures, and run for office yourself."
Mr Obama ended simply, saying it has been "the honour of [his] life to serve [them]".
"Yes we can. Yes we did. Yes we can."
