Jimmy Carter, a US president who struggled with a bad economy and a hostage crisis but was widely admired in his post-White House career, was remembered during his state funeral as a man who put honesty and kindness above politics.
Hundreds of mourners, including all five living current and former US presidents, packed the Washington National Cathedral in Washington, DC.
Fellow Democratic President Joe Biden eulogised the 39th president who died on 29 December at the age of 100.
The US President warned against "hate" and the "abuse of power" in his speech during Mr Carter's funeral.
"We have an obligation to give hate no safe harbour, and to stand up to... the greatest sin of all, the abuse of power," President Biden, who leaves the White House on 20 January, said.
Republican President-elect Donald Trump was among those attending the funeral, before Mr Carter's body is returned to Georgia, where he was raised as a peanut farmer.
Tens of thousands of Americans over the past two days filed through the Rotunda of the US Capitol to pay their respects to Mr Carter, who served from 1977 to 1981, and was awarded the Nobel Peace Prize in 2002 for his humanitarian work.
This morning, a military honour guard carried his flag-draped coffin from the Capitol en route to the Washington National Cathedral.
Some said they admired the former Southern Baptist Sunday school teacher who played a key role in the negotiation of the1979 Egypt-Israel peace treaty as a gentle man, rather than a partisan combatant.
"We've come so far from where Jimmy Carter was as a person and it's kinda sad," said Dorian DeHaan, 67, who traveled some 440km from Sugar Loaf, New York, to pay her respects.
"I hope that this will be a reminder to people of what we need to get back to - that it's not about the power, it's about the people."
As she waited in the public viewing line outside the Capitol, Ms DeHaan said her daughter married into the family of the president's younger sister, Ruth, presenting the opportunity to meet the former president in Plains, Georgia.

"But it's a sad moment," Ms DeHaan said. "It's the end of an era and I think we kind of have lost this real belief inhumanity, in our presidency."
Washington National Cathedral has hosted the state funerals of Mr Carter's immediate predecessor, Gerald Ford, and successor, Ronald Reagan.
He attended both men's funerals and gave the eulogy for Mr Ford, joking that they shared a love of a New Yorker magazine cartoon that depicted a little boy looking up at his father, saying, "Daddy, when I grow up, I want to be a former president."
Following the state funeral, Mr Carter's remains were returned to his native Plains for burial.
He lived there in his 44 post-White House years and made the base of operations for his diplomatic work and charitable efforts including Habitat for Humanity.
He lived longer than any other US president and had been in hospice care for nearly two years before his death.
His last public appearance was at wife Rosalynn's funeral in November 2023, where he used a wheelchair and appeared frail.
In August, his grandson Jason Carter said Mr Carter was looking forward to casting a ballot for Democratic Vice President Kamala Harris in the 5 November election, which she lost to Mr Trump.
Mr Biden, during his long career in the US Senate, was the first member of that chamber to endorse Mr Carter for president.
Sarah Jolie, 59, had traveled from her home outside of Chicago to pay her respects.
She carried a picture of the youth award she received in secondary school from the Carter administration for "outstanding achievement in environmental protection services."
"He just was a hero to me," Jolie said. "He espoused things for generations that nobody else was."
Mr Trump paid tribute to Mr Carter as he lay in state in Washington, standing with his wife Melania for several minutes before Mr Carter's coffin.
Four years ago, the same space was stormed by Mr Trump's supporters seeking - unsuccessfully - to prevent certification of his election loss to Mr Biden.
The Republican made a remarkable comeback in last year's November vote, and will be inaugurated as the 47th US president on 20 January - but flags will be flying at half-mast during the ceremony, in honour of Mr Carter.
That is part of a customary 30-day mourning period for a US president, but Mr Trump has criticised it, saying "no Americans can be happy" about the lowered flags as he takes over from Mr Biden.
Chuck Schumer, the leader of the Democrats in the Senate, described Mr Carter as "one of the most decent and humble public servants we have ever seen".
"President Carter was a living embodiment of leadership through service, compassion, and a thirst for justice for all," he said.
