Joe Biden becomes the 46th US President - 'We must meet this moment as the United States of America'
Joe Biden has been sworn in as the 46th US president at the US Capitol in Washington.
The new President addressed the violence that took place in the same spot he now makes his inauguration speech:
"We learned again that democracy is precious. Democracy is fragile and at this moment, my friends, democracy has prevailed," Biden said.
"Now, on this hallowed ground, where just a few days ago violence sought to shake the Capitol’s very foundation, we come together as one nation, under God, indivisible, to carry out the peaceful transfer of power as we have for more than two centuries."
Speaking of the challenges that his administration will face, including COVID and the rise of "white supremacy", Joe Biden said he will "confront and we will defeat" each obstacle.
He repeated his campaign vow to "restore the soul of the future of America," but said doing so "requires so much more than words".
"It requires the most elusive of all things in a democracy: Unity."
The President called for more mutual respect in society, saying that unity is necessary for American greatness.
"Unity is the path forward."
Vice-president Kamala Harris took her oath too - becoming the first woman to hold that position.
Joe Biden paid tribute to her in his speech: "Here we stand. 108 years ago thousands of protesters tried to block brave women marching for the right to vote."
"Today we mark the swearing in of the first woman in American history elected vice-president - Kamala Harris."
"Don’t tell me things can’t change," he said.
“While I may be the first woman in this office,” Harris vowed in her victory speech in November, “I will not be the last, because every little girl watching tonight sees that this is a country of possibilities.”
Donald Trump did not attend his successor's inauguration - the first president not to do so in 152 years - but his deputy Mike Pence did attend the ceremony.
With Washington DC essentially in lockdown, the Presidential Inaugural Committee announced virtual Inauguration Day events for Americans to watch after urging people to refrain from attending in person.
