Trump was riding a wave of anti-establishment sentiment leading to one of the most improbable political victories in modern US history.
Trump, 70, a real estate developer-turned-reality television star with no government experience, is the 45th president of the United States.
Despite a series of controversies, a record of racist and sexist behaviour, and a lack of political experience, and extreme policies that have drawn criticism from both sides, Trump’s win is a stunning culmination of an explosive, populist and polarizing campaign.
Overlooking an air of improbability that trailed his campaign, his improvisational style and his appeal to disillusioned voters, worked wonders for him.
Thanking the American people for giving a thumping majority, Trump in his speech said the government will serve the people. “Working together, we will begin the urgent task of rebuilding our nation,” he added.
Florida is the largest of the “swing states” with 29 electoral votes. As a Florida victory looked imminent, young Trump fans chanted at giant TVs: ‘Call it! Call it! Call it!’
Next came Ohio, with 18 electoral college votes. Then came North Carolina with 15 votes going to Trump.
He surpassed expectations and confounded pollsters in Florida, where Hillary Clinton had been expected to win following a surge in the Hispanic vote.
Clinton managed to win the battlegrounds of Virginia, Colorado, California but she needed to take Michigan, Nevada, Iowa and Pennsylvania to revive her chances.
It takes 270 votes to win the presidency.
Clinton was in hiding as the result came through. As her party fell flat and supporters streamed away in tears.
