Donald Trump has officially become the 47th president of the United States.
In a special ceremony called an inauguration, President Trump took over from Joe Biden as America’s new leader.
A number of former US presidents, including Mr Biden, attended the ceremony.
It was moved inside the US Capitol building in Washington DC for the first time in 40 years, due to freezing temperatures.
In his first speech as president after swearing the oath, Mr Trump promised to make America “greater, stronger, and far more exceptional than ever before”.
It’s the second time that Mr Trump has taken on the role – having previously served as president before Joe Biden, between 2017-2021.
Mr Trump won the election in November 2024.
In America there is then a delay of two months after the election, as power changes hands from one president’s team to the next.
In order to officially become president, Mr Trump swore an oath to “preserve, protect and defend” the Constitution of the United States.
After Mr Trump was sworn in as president, cannons were fired.
He was seen celebrating with his wife, First Lady Melania Trump, his family and his new vice-president JD Vance.
Following his oath, Mr Trump gave his first speech as president – which is known as the Inaugural Address.
In it, he stated that the “golden age of America begins right now” and that the US will soon be “greater, stronger, and far more exceptional than ever before”.
He added that he felt “confident and optimistic” and that his presidency is the “start of a thrilling new era of national success”.
He also repeated his well-known phrase from the election campaign, by promising to “Make America great again.”

The day started with Mr Trump attending a morning service at St John’s Episcopal Church, which is an inauguration day tradition.
Some of the world’s most powerful tech leaders were also present, including the world’s richest man Elon Musk, Amazon boss Jeff Bezos and Apple’s CEO Tim Cook.
After the church service, Mr Trump and his wife Melania travelled to the White House where they were greeted by outgoing President Biden and his wife Jill.
They sat down together for tea, before it was time to head to the Capitol building for the inauguration ceremony.
Historically, US presidents take the oath outside, in front of huge crowds of supporters that gathered on the grounds of the Mall.
However, bitterly cold temperatures – predicted to reach lows of -11C in Washington DC – meant that proceedings were moved inside, to the Capitol’s Rotunda.
