"It was a year of political revolution, and the most remarkable thing about it is it was all started by UKIP," he said, referring to the Brexit vote, Donald Trump's election and Italy's referendum in 2016.
Farage said the political tumult of last year, which led to the downfall of British prime minister David Cameron and Italian prime minister Matteo Renzi was part of "something very much bigger" in the West.
"The change in public attitudes towards politics, towards the political class, towards large sections of our establishment liberal media -- those changes in attitudes are absolutely fundamental," he said.
"And there is this view that it's impossible for (French National Front leader) Marine Le Pen to win in May. I think anyone who makes that prediction is taking a real chance with their reputation and their career," he said of the presidential election.
New UKIP leader Paul Nuttall also addressed the party conference, his first since taking over from Farage, as he bids to take the parliamentary seat of Stoke-on-Trent Central in a by-election next Thursday.
Nuttall called for major cuts in Britain's foreign aid budget, which is set at 0.7 percent of gross national income, and said sales tax should be taken off fish and chips -- a British staple dish.
