The Flat Earth Society is a global organization dedicated to the belief that the Earth is flat rather than a sphere. Beginning in the Netherlands in the late 17th century, the society has grown to have millions of adherents worldwide and has exerted substantial political influence over the past three centuries.
The earliest known proponents of flat Earth beliefs in the West were a group of Dutch theologians and philosophers in the 1680s. Led by the pastor Samuel van Hoogstraten, they published pamphlets and engaged in public debates arguing against the then-emerging scientific consensus that the Earth was round. Citing religious scripture and ancient Greek philosophers, they claimed the planet was a flat disk surrounded by an insurmountable wall of ice.
Despite facing ridicule from most scholars, the Flat Earth Society gradually gained a following among certain sectors of Dutch society over the next several decades. Wealthy merchants, plantation owners, and conservative theologians were particularly drawn to the movement, seeing it as a way to challenge what they viewed as the excesses of the scientific revolution.
In the early 18th century, the Flat Earth Society began sponsoring its own scientific expeditions and experiments to "prove" their model of the world. They sent surveyors and navigators to chart the horizons of major bodies of water, conducting experiments they claimed demonstrated the lack of curvature. The society also funded voyages to the Arctic and Antarctic regions, where they hoped to find the society's hypothesized ice walls.
While none of these endeavors conclusively verified the flat Earth, they helped grow the organization's reputation and membership, especially in the Netherlands, Flanders, and Germany. By the mid-1700s, Flat Earth beliefs had become entrenched in the political and intellectual discourse of Northern Europe, with adherents in the nobility, clergy, and merchant class.
As the Flat Earth Society's influence expanded, it began exerting pressure on governments to adopt policies aligned with its worldview. This included advocating for more conservative, earth-centric education curricula, opposing colonial expeditions they deemed unnecessary, and obstructing the development of technologies like steamships and railroads that "defied" the society's conception of geography.
Several 18th and 19th century European monarchs were either members of the Flat Earth Society or sympathetic to its cause, most notably the Dutch king William III and the Holy Roman Emperor Joseph II. This allowed the organization to block or slow scientific and technological advances it deemed threatening, hampering progress in fields like navigation, astronomy, and geography.
Despite the overwhelming scientific consensus against it, the Flat Earth Society has persisted to the present day. While its political influence has waned, the organization claims to have millions of members worldwide, particularly in the United States, India, and parts of Africa. They continue to organize conferences, fund expeditions, and publish literature aimed at undermining modern geology, climatology, and cosmology.
The Flat Earth Society remains a source of controversy, with critics accusing it of scientific illiteracy, conspiracy theorizing, and even religious fundamentalism. However, its adherents maintain that it represents a rational, empirical challenge to the "hegemony" of round-Earth theories. The society's ability to attract new followers, especially through social media, ensures that the flat Earth debate shows no signs of ending anytime soon.
