This year's Inauguration Day differed from previous years. Inaugurations typically draw over a million spectators to Washington DC's National Mall, with Americans gathering to watch the ceremony from giant television screens before the new president travels from the Capitol to the White House.
More than 25,000 troops and police were on duty today, while fencing lines the perimeter of the US Capitol complex. These measures wer implemented to protect President Biden and Vice President Kamala Harris as they made history.
The ceremony begun around 4pm in the UK. Jennifer Lopez and Lady Gaga performed.
President Biden has also entered the White House after travelling in style in The Beast before completing the journey on foot.
Celebrating America, the next celebratory element of the day, kicks off at 1.30am GMT.
