In 1918, Henry Ford purchased his hometown newspaper, The Dearborn Independent. A year and a half later, he began publishing a series of articles that claimed a vast Jewish conspiracy was infecting America. The series ran in the following 91 issues. Ford bound the articles into four volumes titled "The International Jew," and distributed half a million copies to his vast network of dealerships and subscribers.
The Protocols of the Elders of Zion was a notorious forgery that originally came from Russia, and [was] translated into English. [It] claimed the existence of an international Jewish conspiracy -- that a group of Jews got together and basically planned the fate of the world, be it financial catastrophe, be it war. The world was controlled by this little cabal of Jews. [This forgery was] printed in The Dearborn Independent as a factual piece. And so someone reading it would take this to be the news.
There are lots of small town newspapers that publish scurrilous anti-Semitic material, so it wasn't unusual in that way. But what's notable about The Dearborn Independent is that it was also spread through the Ford Motor dealerships. And so that there'd be stacks of them in a dealership in California, dealership in Massachusetts, a dealership in Iowa. In some places, the dealership would actually put copies of the newspaper in the car, so that when you drove off with your Model T, there you had on the seat next to you a copy of The Dearborn Independent.
And because The Dearborn Independent was published by Ford, it meant that other newspapers would pick up on what he said, and if only in reporting on an article that appeared in The Dearborn Independent, it meant that it got much greater currency than if it had just been a small-town newspaper in some equivalent sized town in Wisconsin or Montana. But this was Henry Ford's newspaper, and pretty much anything Henry Ford did was news.
