Seven times Barack Obama cried during an emotional eight years
Barack Obama became tearful as he made his farewell speech as US president on Tuesday night in Chicago.
It was mention of his wife Michelle and daughters Sasha and Malia that made him cry.
"You made the White House a place that belongs to everybody," he said of the first lady.
"And a new generation sets its sights higher because it has you as a role model."
During his time in office he introduced affordable healthcare to the US and legalised gay marriage, but said his daughters were his greatest achievement.
"Of all that I've done in my life, I'm most proud to be your dad," he said.
These are the some of the moments that moved Obama to tears across his presidency.
The loss of his grandmother
Barack Obama's grandmother, Madelyn Dunham, died from cancer on November 3 2008, the last day of his campaign for presidency.
He paid tribute to her during a speech at the University of North Carolina.
"She has gone home," he said, before telling crowds her loss was "hard to talk about".
The death of Dorothy Height
Dorothy Height was known as the "Godmother of American civil rights" and once marched with Martin Luther King Jr.
Dorothy died aged in 2010 at the age of 98. She had continued to campaign long into her nineties.
And she was seated on the stage during Obama's inauguration the previous year.
The Sandy Hook school massacre
Twenty children, aged between six and seven years old, and six teachers were shot dead by Adam Lanza in 2012 at Sandy Hook elementary school.
"I can only hope it helps for you to know that you're not alone in your grief," said an emotional Obama in a speech following the attack.
"We have wept with you, we've pulled our children tight."
The funeral of Daniel Inouye
Daniel Inouye was a Hawaiian US senator for 49 years, between 1963 and 2012.
Barack Obama was born in Hawaii and after Inouye's death said his career had been inspired by the Asian/American politician.
"The way he commanded the respect of an entire nation, I think it hinted to me what might be possible in my own life," Obama said in 2012.
The Aretha Franklin moment
When it comes to surprise guests, it doesn't get much bigger than the queen of soul herself, Aretha Franklin.
Barack and Michelle Obama were guests at a tribute to songwriter Carole King in Washington in 2015 when Aretha performed (You Make Me Feel Like) A Natural Woman.
It's safe to say the 74-year-old singer absolutely smashed it.
The video of the moment, televised by CBS, has been viewed millions of time on YouTube.

The introduction of new gun laws in the US
"Every time I think about those kids, it gets me mad," said Barack Obama about the victims of the Sandy Hook massacre as he introduced new gun laws in America in January 2016.
In 2015 he told BBC that his failure to pass "common sense gun laws" in the US was the greatest frustration of his presidency.
His attempts to change the laws have always been blocked by the Republicans.
