Today, October 1, is World Vegetarian Day. The North American Vegetarian Society started the holiday in 1977, and the International Vegetarian Society picked it up the next year. But the history of vegetarianism in the West stretches back far, far earlier, all the way to the 19th century. And the early days were ... well, sometimes they were a bit weird.

Back in the 1800s, people in England first began to organize groups that promoted vegetarianism as a means of preserving animal life. The 1809 founding of the Bible Christian Church marked an early starting point, and other organizations — both religious and secular — followed. As early as 1811, potential vegetarians could find arguments in books like John Newton's strident testimonial The Return to Nature:

In the ensuing decades, vegetarianism grew in popularity, thanks to advocacy from some religious groups and support from parts of the medical community (one example, from 1838: Vegetable Diet, as Sanctioned by Medical Men, and by Experience in All Ages). The movement spawned influential journals and attracted key converts, including celebrity adherents like poet Percy Bysshe Shelley. The 1847 founding of the Vegetarian Society only confirmed the trend. Early vegetarians occasionally threw great parties, too, like the 1851 Soiree of the Vegetarian Society, which featured both moral abstention from meat and exaggerated health claims: "[One man] by the abandonment of flesh-meat was cured of long-standing dyspepsia and asthma" — A report on the 1851 Soiree

Vegetarian societies were exclusive clubs that often held eccentric opinions. Vegetarianism was a subculture, and sometimes one that stood far, far out of the mainstream. In places like Ascona, Switzerland, in the 1900s, vegetarianism mixed with avant-garde communal nudist life (the colony was started by an "anarchist physician"):

Even if it was far from the mainstream, vegetarianism managed to persist for decades. It certainly didn't hurt that some of its key advocates, like playwright George Bernard Shaw, were especially passionate about the cause — and willing to give great quotes. "While we ourselves are the living graves of murdered beasts, how can we expect any ideal conditions on this earth?" — A quote attributed to George Bernard Shaw

But celebrity endorsements weren't all that kept vegetarianism going. It took the continuing work of activists as well as entrepreneurship. This Parisian vegetarian restaurant, photographed in 1931, was one of a few run by the Trait D'Union's Naturist Society (a nudist group). Diners were, happily, all clothed.

As time went on, vegetarianism shed some old associations and gained new ones. Like religion before it, nudism ceased to become a defining feature of vegetarianism, and eventually hippies embraced the movement, as seen in the Whole Earth restaurant in 1977.
