And his message of America first and "make America great again" resonated with millions in the US.
In his own words, he is the "last chance" to fix a broken country and a "last chance" to fix immigration and trade.
The billionaire managed to craft his own political brand, building a movement among the Republican Party's disaffected rank-and-file.

Donald Trump: From real estate mogul to would-be president
Asked whether Mr Trump or House Speaker Paul Ryan, the highest-ranking Republican elected official, better represent the party's values, 51% of members choose Mr Trump and 33% favoured Mr Ryan.
Mr Trump divided the party, both with his brash style and by overturning conservative orthodoxy with his opposition to free trade, isolationist foreign policy and flexible stance on welfare and deficits.
During his energetic and controversial election campaign, he built up an enormous database of supporters.
Mr Trump played masterfully on frustrations with the Washington and Wall Street elites, vowing to champion blue-collar male white voters' concerns about economic exclusion.
But as he did so, he insulted or managed to offend women, immigrants, African Americans, Muslims and those with disabilities - deepening US's divides.
He had no problem filling vast halls with motivated voters, and his 60% unfavorable opinion poll rating would have sunk a less shameless campaigner.
Throughout his campaign he described a dark United States that had been knocked to its knees by China, Mexico, Russia and so-called Islamic State.
The American dream was dead, he said, smothered by malevolent business interests and corrupt politicians, and he said he alone could revive it.
Mr Trump said he will make the US great again through the force of his personality, negotiating skill and business acumen.
He offered vague plans to win economic concessions from China, to build a wall on the southern US border to keep out undocumented immigrants and to make Mexico pay for it.
He has vowed to repeal Obamacare while being the "greatest jobs president that God ever created" and proposed refusing entry to the United States of people from war-torn Middle Eastern nations, a modified version of an earlier proposed ban on Muslims.
Mr Trump promoted himself as the ultimate success story. Everything in his life was the greatest, the hugest, the classiest, the most successful.
He is controversial, hated by millions, worries the international community, but his message echoed around the US.
Now, he is set to become the 45th President of the United States.
His first 100 days
During the campaign, he laid out proposals for his first 100 days in office, vowing to bring change to a "broken system" in Washington.
The billionaire real estate magnate has vowed to "drain the swamp in Washington" and replace it "with a new government of, by and for the people" - echoing Abraham Lincoln's famous 1863 Civil War address.
"Change has to come from outside our very broken system," Mr Trump said in an October speech.
"Our campaign represents the kind of change that only arrives once in a lifetime."
Mr Trump has pledged to deliver "at least 25 million jobs in one decade".
He said he would tame illegal immigration, impose congressional term limits, renegotiate the North American Free Trade Agreement (NAFTA) - and repeal US President Barack Obama's signature health care reform.
He also said he would "cancel billions in payments to UN climate change programmes" and use the savings "to fix America's water and environmental infrastructure".
Mr Trump also listed many of his familiar campaign pledges, such as renegotiating or pulling out of trade deals like NAFTA and the Trans-Pacific Partnership (TPP).
During his election campaign, he said:
"I am not a politician, and have never wanted to be one."
"But when I saw the trouble our country was in, I felt I had to act."
