How Did The Running Of The Bulls Become A Tradition? | Origins

The running of the bulls became a tradition when cattle drives through Pamplona merged with San Fermín feast and turned work into a street spectacle.

Photos of Pamplona’s narrow lanes packed with runners in white and snorting bulls in front of them appear on travel shows and social feeds across the globe. Many visitors daydream about joining that dash, while others only plan to watch from a balcony and keep a safe distance.

Either way, the same puzzle comes up again and again: how did the running of the bulls become a tradition? How did a risky sprint with animals turn into one of Spain’s best-known summer rituals and a magnet for travellers from many countries?

The story stretches across cattle trade, a Catholic feast day, local fairs, and centuries of repetition. Once bulls needed to move from the fields to Pamplona’s bullring before afternoon fights, neighbours started to run with them for bragging rights. Over time that practical chore fused with the San Fermín festival, picked up songs, symbols, and rituals, then reached global fame through books, television, and modern tourism.

How The Running Of The Bulls Became A Festival Tradition Over Time

To see how a simple cattle drive turned into the encierro that fills Pamplona’s streets each July, it helps to trace the main milestones. The outline below brings together the work, faith, and fairground strands that shaped today’s running of the bulls tradition.

Period	Change	What It Added To The Tradition
13th–14th centuries	Bulls driven from fields outside town to markets and early bullrings.	Linked bulls with town life and regular trade routes.
Late Middle Ages	Young drovers and locals run beside the herd to help guide it.	Introduced speed, danger, and a test of nerve for local youths.
14th–15th centuries	Commercial fairs grow around Pamplona, drawing farmers, merchants, and entertainers.	Bull events slide naturally into fair week as shared town entertainment.
12th–16th centuries	Religious celebrations in honour of Saint Fermín gain processions and mass.	Gives the festival a patron saint, prayers, and a calendar date.
1591	Authorities move the saint’s feast from September to July to match fair dates.	Religious events, markets, and bull runs merge into one summer fiesta.
18th–19th centuries	The term “encierro” spreads, and the route through Pamplona’s old streets becomes fixed.	The run gains a clear identity, rules, and a recognisable course.
20th century	Ernest Hemingway writes about San Fermín and the bull runs in “The Sun Also Rises.”	International visitors arrive, and the running of the bulls becomes a global symbol of Pamplona.
Late 20th–21st centuries	Television, stricter safety rules, and mass tourism reshape the fiesta.	The encierro remains central but now sits inside a crowded, highly organised festival.

This timeline shows that the running of the bulls never sprang from a single decree or marketing idea. It grew step by step from daily work that already brought bulls into the old quarter, then wrapped itself around a saint’s feast and a growing fair.

Once the bulls had to reach the ring each afternoon, the morning route turned into an event that people expected year after year. Songs, dress codes, meeting spots, and rivalries between streets slowly formed around that run, until skipping it felt unthinkable for many local runners.

Medieval Cattle Drives And Early Bull Runs

Centuries ago, bulls for the afternoon fights grazed on land outside Pamplona. On feast days and during fairs, herders needed to bring the herd through narrow streets to reach the temporary or permanent bullring. Horses, long poles, and shouts pushed the animals along, while townspeople watched from doorways and balconies.

At some point, young men working with the cattle and daring locals began to run beside the animals instead of staying behind them. What started as a practical way to keep the herd together soon turned into a chance to show speed and bravery. The closer a runner stayed to the horns without falling, the more prestige he gained among friends and neighbours.

Spanish tradition traces these bull runs to the north-east of the country in the late Middle Ages, then into Pamplona as fairs grew in size. By the time written records mention similar events, the habit of racing along with the herd already felt familiar in several towns that held bullfights.

From Work Chore To Daily Ritual

For locals, the routine stayed the same: bulls arrived near dawn, they moved through town behind fences or lines of guards, and they ended in the ring. Over generations, though, more elements wrapped around that routine. The same families watched from the same balconies, parents told stories about great runs from earlier years, and the line between work and festival blurred.

As this pattern repeated each summer, people stopped asking whether the run should happen and instead asked small questions about start time, routes, and safety. That slow shift from “Is this happening?” to “How will we do it this year?” is part of how the running of the bulls became a tradition long before tourists heard about it.

San Fermín, Fairs, And Town Life Blend

The modern San Fermín festival rests on three old threads: a religious celebration for Saint Fermín, a trade fair, and the morning bull runs. Regional records show a feast for the saint from at least the twelfth century, while fairs drawing farmers and merchants are documented from the fourteenth century around Pamplona.

On today’s official San Fermín history page, the region of Navarre describes how these three strands slowly came together. Religious ceremonies honoured the patron saint, the fair brought stalls, entertainment, and livestock into town, and bulls were herded in for fights and trade. When local leaders moved the saint’s day to July in 1591 to avoid wet autumn weather, the feast lined up with the fair and the bull events in one sunny week.

From that point, the running of the bulls sat inside a wider July fiesta with music, processions, open-air meals, and late-night street life. The encierro kept its practical goal of moving fighting bulls to the ring, yet it picked up prayers, songs to Saint Fermín, and its own dawn rituals before the first rocket sends the herd on its way.

Pamplona’s city website explains how the word “encierro” slowly replaced earlier names for the run in the nineteenth century, and how today’s route through Santo Domingo, Town Hall square, Estafeta street, and into the ring became fixed over time. That official encierro overview stresses that, even now, the event exists to deliver the bulls safely to the afternoon corrida.

How Locals Turned A Dangerous Chore Into A Tradition

Once the saint’s day, the fair, and the run lined up on the calendar, the encierro became the daily spark that opened each festival morning. Locals woke to the sound of rockets, gathered along the wooden fences, and watched neighbours they knew by name sprint in front of the herd. Each run carried tales of close shaves, falls, and daring moves that people retold over drinks for the rest of the day.

Over time, small customs turned that morning dash into a ritual. Runners visited the statue of Saint Fermín at dawn to sing for protection. Others tied on red scarves and waistband sashes in the same order every July. Bars along the route opened early for coffee, while balcony owners hosted the same friends each year. These repeated details gave the running of the bulls a shape regular people could recognise and pass down.

How Did The Running Of The Bulls Become A Tradition?

The encierro became a tradition because locals kept repeating it with meaning. Every year bulls still had to reach the ring, so the practical need never went away. At the same time, families linked memories and stories to the run: a grandfather’s fall near the town hall corner, a cousin’s first sprint on his eighteenth birthday, a neighbour who always sings louder than anyone else at the dawn prayer.

Tourists often arrive in Pamplona asking the same question out loud: “how did the running of the bulls become a tradition?” The honest answer blends logistics and emotion. Bulls needed moving; people turned that job into a festival act that let them show courage, devotion to their town, and loyalty to Saint Fermín, so they kept doing it.

From Local Custom To Global Symbol

For centuries, word about the running of the bulls rarely travelled far beyond northern Spain. That changed in the early twentieth century when Ernest Hemingway visited Pamplona, fell in love with the fiesta, and used it as the backdrop for his novel “The Sun Also Rises” in 1926. The book painted San Fermín as a wild, romantic, sleepless festival with the encierro at its heart, and readers around the world took notice.

Later, newsreels, colour photography, and live television carried images of runners in white and red dodging bulls through the cobbled streets. Travel writers and tour operators followed, presenting the event as a bold test for adventurous visitors. Each fresh wave of publicity drew more guests to Pamplona, many of whom came specifically to take part in or watch the running of the bulls tradition they had seen on screens.

The rise in visitor numbers forced the city to set clearer rules. Only adults over eighteen may run, participants must head in the same direction as the herd, and police remove people who appear drunk or reckless. Medical teams wait at key points along the 800-plus metre route, which still follows the old lanes from Santo Domingo up to the bullring, and every run finishes in the arena where bullfights take place later that day.

Modern Meaning Of The Running Of The Bulls For Travelers

Today, the encierro sits inside a packed week of concerts, fireworks, parades, and long street gatherings. For locals, it remains the sharpest moment of each morning, a mix of nerves, pride, and habit. For visitors, it can be both a bucket-list thrill and a scene that raises questions about risk and about the treatment of animals.

Travelers do not need to run to feel the pull of the tradition. Many people watch from balconies, from gaps in the fences, or on large public screens. Others take in the music and late-night parties while skipping the run completely. Animal-rights groups stage protests each year, arguing that the stress on the bulls and the killing in the ring at the end of the day have no place in a modern holiday.

If you decide to travel to Pamplona during San Fermín, it helps to know how present-day runs compare with their historical roots.

Aspect	Earlier Practice	Today’s Experience
Main purpose	Move bulls from countryside to the ring for fights and trade.	Still moves fighting bulls, but also acts as a headline tourist event.
Who runs	Mostly local herders and young men from nearby streets.	Mix of experienced locals and visitors from many countries.
Timing	Linked loosely to fair days and feast dates.	Fixed at 8 a.m. on 7–14 July during San Fermín.
Route	Varied when bullrings moved or when temporary rings were used.	Stable 800-plus metre course along fenced streets to the current ring.
Safety measures	Simple wooden barriers and local helpers.	Detailed rules, medical teams, radio links, and instant television coverage.
Clothing	No single style; work clothes or simple shirts.	White outfits with red scarf and sash, copied by visitors and locals alike.
Public debate	Little written debate beyond local concerns about injuries.	Active debate about safety, animal welfare, and whether bull events should continue.

This table shows that the core of the running of the bulls tradition still matches its roots. Bulls move from holding pens to the ring at dawn while people run ahead of them. Around that core, media exposure, tourism, and modern safety planning have added new layers that shape how visitors experience the event.

For many travellers, learning how did the running of the bulls become a tradition adds depth to any visit to Pamplona. Whether you stand behind the fence at Santo Domingo, book a balcony along Estafeta, or simply watch a broadcast from home, understanding that mix of medieval cattle work, saint’s feast, and local habit makes the spectacle more than a quick clip on a screen.
