Joe Biden replaces Trump as US president
Joe Biden has been sworn in as the 46th US president, ending one of the most dramatic political transitions in American history.
“Democracy has prevailed,” he said after taking the oath of office from Chief Justice John Roberts.
Donald Trump, who has not formally conceded to Mr Biden, did not attend the ceremony.
The new president has announced a raft of executive orders aimed at reversing Mr Trump’s key policies.
Kamala Harris was sworn in as vice-president ahead of Mr Biden.
She is the first woman – and the first black and Asian-American person – to serve in a role, a heartbeat from the presidency.
The inauguration took place at the US Capitol. There is extra-tight security after the building was stormed by violent pro-Trump protesters in a deadly riot on 6 January.
Some 25,000 National Guards are protecting the ceremony, which is missing the traditional hundreds of thousands of spectators because of the coronavirus pandemic.
In his inaugural address, Mr Biden said it was a day of “history and hope”.
“My whole soul is in putting America back together again,” he added.
Highlighting a message of unity after the turbulent Trump years, he promised to be a president “for all Americans” – including those who voted against him.
