Leidens Ontzet: a day of freedom, fun, and boozing!

Every year, there’s one day that all Leiden residents look forward to, Leidens Ontzet (Relief of Leiden). Every year on October 3rd, people treat themselves to a city-wide party full of food, games, carnival rides, and most importantly: alcohol!

It might be the only day that Leiden’s large student population intermingles with the locals, as they sing the Leiden anthem or the October 3 song of ‘Rubberen Robbie together in brotherly love. 🍻

Important: Leidens Ontzet is much more toned down this year in 2021 due to the coronavirus pandemic. Certain measures are being taken for the event this year.

From my own experience, I can tell it is truly the most beautiful day of the year. For the people who don’t know what I’m talking about, I will explain this exceptional phenomenon to you and clarify some crazy scenes you might see on this day.

The history of Leidens Ontzet

A pretty long time ago, the Dutch were at war with the Spaniards in the so-called Eighty Years War (1568-1648). Like all wars during this time, this war was about religion, independence, and power.

The rule of the Spaniards, Catholic King Philip II, was a repressive old crook that didn’t want the Dutch to be independent. This was obviously ridiculous, and so they legitimately rebelled against this paella-creep.

The city of Leiden was attacked by the Spaniards for the first time in October 1573. However, under the guidance of Francisco de Valdez, they were distracted by Lodewijk van Nassau’s Dutch army.

Van Nassau was the brother of William of Orange, the Dutch freedom fighter. Therefore, he had to help his Spanish colleagues at the Mookerhei (nearby Nijmegen) where this Dutch crook was settled. He then had to give up the siege of Leiden on March 21, 1574. But the Spaniards came back to lay siege to Leiden – with 5000 men – and this time it lasted until October 3.

In the meantime, the citizens of Leiden didn’t have enough food and diseases spread all over the city. Thousands of people died from starvation and the plague. The city secretary, Jan van Hout, and the leader of the troops, Jan van der Does, were stubborn as hell and didn’t want to surrender to this Sangria-dude.

It was a heroic fight, especially when Mayor Van der Werf offered his arm as food to his starving people. Such self-sacrifice must certainly be remembered for eternity…even though it’s a myth. Van der Werf even has a park named after him with a huge statue dedicated to his honour.

On October 3, 1574, the siege came to an end, because of William of Orange’s genius plan. He decided to flood the surrounding areas of Leiden by making holes into the dykes of Holland to expel the Spaniards.

When the surrounding areas were flooded at the beginning of October, the ‘Watergeuzen’ (water rebels) were making their way to Leiden to set the citizens of Leiden free. The cowardly Spaniards totally panicked because of the water and the Watergeuzen, and so they ran away like chickens — back to where they belong. 🐔

The people came out of their houses to see if the Spaniards were really gone. The only thing the Spaniards left was a porridge pot with hutspot (mashed potato and vegetable dish), while the Watergeuzen brought herring with white bread into the city.

First thing in the morning, all the citizens went to the Pieterskerk, where they thanked God for this miracle that happened. And so we thank God for his effort until this day and honour this miraculous moment by drinking and partying as much as we can, every October 3rd.

Did you know? William of Orange proposed to establish the first university in the Netherlands as a reward for defeating the Spanish. In 1575, Leiden University was inaugurated in the Pieterskerk.

How to party the Leiden-way

Eat some food and ride some rides

You may be asking yourself: is Dutch food even a thing? Yes, it actually is!

While the holiday technically starts on October 3rd, most people actually begin the festivities on the night of October 2nd. On this night, Leiden people eat hutspot (a dish of mashed potatoes and vegetables) and then they go out on the town for drinking and debauchery!

When you wake up from your hangover on the morning of October 3rd, you can make your way to the Waag for FREE herring and white bread. 😋

After finishing this “Dutch delicacy”, you can head into the city and take a look at the magnificent Taptoe parade with lights and fun performances.

After that, you should walk around the funfair in the city centre and lose your money trying to win a stuffed animal for your partner. Here, you can eat some churros, deep-fried doughnuts and get on some roller coaster rides (though you may want to do the rides before eating the snacks 🙈).

Get drunk and watch some fireworks

Did I mention that you should drink alcohol all the time while doing these things? Then, while being a bit tipsy or drunk already, you can take a look at all the stages in the city where you can listen to all kinds of music, especially those you don’t want to hear when you’re sober. 💃

Then, just before midnight, you can watch a spectacular fireworks show at the Zijlsingel. 🎆 After that, you can slowly move to a pub that’s overly hot and everyone is hammered until the sun comes up.

If you’re somehow able to walk at the end of the evening, it’s allowed to go to bed before you pick up your herring and white bread (again) the next morning on October 4th. Then the fun is over, and you’ll have to wait another year to do it all again!

  1. You forgot the “gerookte paling, ” smoked eel, and the fact that Leiden, as a reward for its heroism, was given a University, founded in 1575

  2. […] The relieve of Leiden, or better said – driiieeee oktober, is one of the most Leiden-ish events you can possibly be a part of when you’re living in Leiden. During the event Leiden will be transformed into an open-air party celebrating the end of the Spanish siege of the city in the 16th century. There’s a big fair, a grand party everywhere on the 2nd of October, hutspot and herring and beer (lot’s of it). Here’s our article on the Leidsch Ontzet. […]
