When the first modern Olympics kicked off in Athens in 1896, it wasn’t clear they’d last. After a so-so debut, the Olympic Games continued in 1900 and 1904, but not as a main attraction. Both were part of the world’s fairs in Paris and St. Louis, respectively.
“This is difficult for us to sort of conceive in the modern age,” says Craig Greenham, a professor of kinesiology at the University of Windsor in Ontario, but the 1900 and 1904 Olympics were “second fiddle to the world’s fairs.”
In fact, some people who attended the world’s fairs ended up signing up for and competing in the Olympic Games while they were there, Greenham says.
