In 1927, Donald Trump’s father was arrested at a Ku Klux Klan riot in New York

A furore over former Ku Klux Klan grand wizard David Duke’s praise for Donald Trump has brought back into the spotlight an incident from nearly 90 years ago, in which Trump’s father was arrested at a Klan riot in New York.

In September, the technology blog Boing Boing reported that on Memorial Day 1927, brawls erupted in New York led by sympathisers of the Italian fascist movement and the Ku Klux Klan. In the fascist brawl, which took place in the Bronx, two Italian men were killed by anti-fascists. In Queens, 1,000 white-robed Klansmen marched through the Jamaica neighbourhood, eventually spurring an all-out brawl in which seven men were arrested.

One of those arrested was Fred Trump of 175-24 Devonshire Rd in Jamaica.

This is Donald Trump’s father. Trump had a brother named Fred, but he wasn’t born until more than a decade later. The Fred Trump at Devonshire Road was the Fred C. Trump who lived there with his wife, according to the 1930 Census.

The predication for the Klan to march, according to a flier passed around Jamaica beforehand, was that “Native-born Protestant Americans” were being “assaulted by Roman Catholic police of New York City.” “Liberty and Democracy have been trampled upon when native-born Protestant Americans dare to organize to protect one flag, the American flag; one school, the public school; and one language, the English language.”
