This is the shocking moment that 20,000 people cheered on the idea of a white supremacist USA in New York's Madison Square Garden - in the guise of a 'pro-American rally'.

The footage, shot on February 20, 1939, shows the audience throwing Nazi salutes as the American flag is carried to a stage bedecked with a 30-foot-high painting of George Washington flanked by swastikas.

The Pledge of Allegiance is then read out before the group's leader, German-American Fritz Kuhn, gets up to denounce the 'Jewish media' and call for America to be 'returned to the American people ... a white, gentile-ruled United States'.

This Nazi rally in Madison Square Garden attracted 20,000 people in 1939 - while banners with Nazi swastikas hung next to a picture of George Washington (both seen leftleft)

The event was a 'pro American rally' according to its organizers (left) and saw Fritz Kuhn (right) leader of the German American Bund, calling for a 'white, gentile-ruled United States'

August's Unite the Right rally in Charlottesville, which saw Nazis openly chanting about Jews and assaulting counter-protesters, seemed to some like an aberration in modern America.

But this seven-minute clip, compiled by Oscar-nominated documentary filmmaker Marshall Curry for Field_Of_Vision, shows an even larger gathering - in New York, which even in the 1930s was considered a liberal bastion.

Curry edited together the clips from fragments showing unrest outside Madison Square Garden, while inside Kuhn spouts anti-Semitic rhetoric.

The rally is interrupted when Isadore Greenbaum, a 26-year-old Jewish plumber's helper from Brooklyn, rushes the stage.

He's then thrown to the crowd and beaten by a group of fascists before the police arrive to haul him off. He was stripped of his trousers, Curry said.

The NYPD arrested him for disorderly conduct and fined $25 ($431 today).

The clip ends with the crowd standing for the Star-Spangled Banner, and text noting that Hitler was building his sixth concentration camp at the time.

Jewish plumber's helper Isadore Greenbaum (seen being hauled off by cops, 26), rushed the stage and was beaten, had his pants removed, and was arrested. he was fined $25 for disorderly conduct

At the beginning of the ceremony the crowd gave Nazi salutes to the American flag. At the close of the event, a woman since The Star-Spangled Banner. Kuhn demanded that America's government 'be returned to the American people'

'A friend of mine told me about it last year, and I could't believe that I'd never heard of it,' Curry said of the rally, according to Field_Of_Vision.

'When I found out it had been filmed, I asked an archival researcher, Rich Remsberg, to see what he could find.'

Curry continued: 'So he gathered it, and I edited it together into a short narrative. When Charlottesville happened, it began to feel urgent.'

The event was hosted by the German American Bund, which had training camps in upstate New York, as well as New Jersey, Pennsylvania and Wisconsin - and which was terrifyingly popular in the US at the time.

But despite the thick accents sported by Kuhn and his cronies, the gatherings were presented as 'pro American rallies.'

Indeed, those very words are seen on the sign outside the building, along with more mundane events: 'Hockey Tues night, Rangers vs Detroit; Basketball Wed night, Fordham vs Pittsburgh.'

And at the time - when Hitler's persecution of the Jews in Europe was well known, but before the full horror of concentration camps had been revealed - these attitudes were not uncommon.

Prior to the Second World War, pro-Nazi sentiment was accepted as part of the public discourse, and celebrities were not afraid to show they agreed with it. Only after the US entered the war did it begin to hide those aspects of its society

'In a part of Fritz Kuhn’s speech that isn't in the film, he applauds Father Coughlin, whose radio shows praising Hitler and Mussolini reached audiences of 30 million,' Curry said.

'Henry Ford and Charles Lindberg expressed anti-Semitic beliefs.

'And press magnate William Randolph Hearst declared, "Whenever you hear a prominent American called a fascist, you can usually make up your mind that the man is simply a loyal citizen who stands for Americanism."'

Perhaps with that in mind, Curry invoked a quote from Halford E Luccock, a New York Times reporter of the period.

The reporter wrote: 'When and if fascism comes to America it will not be labeled "made in Germany"; it will not be marked with a swastika; it will not even be called fascism; it will be called, of course, "Americanism."'

'To me, the most striking and upsetting part of the film is not the anti-Semitism of the main speaker or even the violence of his storm-troopers,' Curry said.

'What bothers me more is the reaction of the crowd. Twenty-thousand New Yorkers who loved their kids and were probably nice to their neighbors, came home from work that day, dressed up in suits and skirts, and went out to cheer and laugh and sing as a speaker dehumanized people who would be murdered by the millions in the next few years.

'This point is less an indictment of bad things that Americans have done in the past, than it is a cautionary tale about the bad things that we might do in the future.'

Tens of thousands packed out the stadium, while police were seen outside on horses. Oscar-nominated documentary maker Marshall Curry, who put together a seven-minute clip from news footage, has likened it to Donald Trump's rallies

Marshall said he felt the need to push the clip out into the public domain in the wake of August's mass white supremacist rally in Charlottesville. He says he's worried that ordinary Americans can be pushed into a life of hate by fascist rhetoric

Curry makes no bones about comparing Kuhn to President Donald Trump, whose own rallies had attracted support from fascist members, as well as the more mainstream American right.

'It really illustrated that the tactics of demagogues have been the same throughout the ages,' he said.

'They attack the press, using sarcasm and humor. They tell their followers that they are the true Americans (or Germans or Spartans or...).

'And they encourage their followers to "take their country back" from whatever minority group has ruined it.'

Kuhn was arrested for embezzling the German American Bund's money and imprisoned in December 1939.

He was stripped of US citizenship in 1943 and deported to West Germany in 1945, at the close of the Second World War - by which point the US was grateful to forget its open flirtation with fascism.

'In the end, America pulled away from the cliff, but this rally is a reminder that things didn't have to work out that way,' Curry said.

'If Roosevelt weren't President, if Japan hadn't attacked, is it possible we would have skated through without joining the war?

'And if Nazis hadn't killed American soldiers, is it possible that their philosophy wouldn’t have become so taboo here?'
