Every year on 1 April, millions of people around the world delight in harmless pranks and practical jokes. The origins of April Fools' Day, however, remain a puzzle that has intrigued historians for centuries. Evidence suggests the holiday could be over 600 years old, but scholars disagree on how it began.

From medieval England to royal calendar reforms in France and ancient spring festivals, the roots of the day reveal a complex and surprising history behind the pranks that have become a modern tradition.

Three Competing Theories for April Fools'

Historians have identified three main theories to explain how April Fools' Day emerged, according to National Geographic's examination of the holiday's contested history. The first theory points to England, where the poet Geoffrey Chaucer may have recorded one of the earliest references in his Nun's Priest's Tale, written around 1390.

The tale describes a rooster and a fox attempting to deceive each other, and refers to pranks occurring '32 days after the beginning of March', which would coincide with 1 April. Some scholars suggest that scribal errors could affect this interpretation, leaving the English origins open to debate.

The second theory comes from France, which has long celebrated 'Poisson d'Avril', or April Fish. This tradition involves attaching a paper fish to a person's back without them noticing and shouting 'April fish' when the trick is revealed.

French poet and composer Eloy D'Amerval referenced an 'April fish' in his 1508 work, Book of Deviltry, providing historical evidence for the custom.

The third theory links the holiday to calendar confusion. In 1564, the French king Charles IX issued the Edict of Roussillon, declaring that the new year would begin on 1 January.

Prior to this reform, different regions of France celebrated the new year on different dates. Some believe that those who continued to celebrate in April were mocked as 'fools', potentially sparking the tradition of April pranks.

Ancient Festivals and Spring Celebrations

The practice of seasonal pranks predates Europe's April Fools' Day. In ancient Rome, the festival of Hilaria, celebrated after the vernal equinox, involved masquerades, role reversal, and playful deception.

Roman historian Herodian noted that participants could disguise themselves as anyone and play the fool by concealing their true identity.

Similar customs exist in other parts of the world. The Hindu festival of Holi, celebrated in March, incorporates light-hearted pranks and playful mischief.

In Iran, Sizdah Bedar, held 13 days after the vernal equinox, includes harmless jokes and pranks as part of the Nowruz spring festival, a tradition dating back to 536 BCE. These festivals demonstrate that springtime has long been associated with humour, disguise, and social levity.

Historical Evidence of Pranks

April Fools' pranks have taken many forms over the centuries, from medieval literary references to the playful 'April fish' in France.

The enduring appeal lies in the combination of mischief and harmless fun. Folklorist Stephen Winick has described the holiday as a mystery preserved by competing theories, each adding a layer to the story of pranks and foolery.

Even with more than a century of scholarly research, the precise origins of April Fools' Day remain unclear. Historian Alan Dundes noted in 1988 that over 100 years of scholarship had added very little to understanding the holiday.

What is certain is that 1 April has long been a day for laughter, tricks, and playful deception, continuing a tradition that stretches back to medieval Europe and ancient festivals around the world.
