A local cultural association organised a day trip to Madrid on the 31st of January to witness the historical re-enactment Día de Los Tercios (Tercios Day). Tercios (thirds) were the Spanish Empire’s infantry force, usually considered to be the origin of modern European armies. They were formed by volunteers-turned-professional soldiers, the elite of the Spanish military.
Despite their 1534 establishment as an actual unit, the strategies and structure of the Tercios can be traced to the 1480s, when the Christians were trying to conquer Grenada from the Arabs. They were known for effectively mixing bladed weapons, usually pikes, and firearms (primitive rifles known as arquebuses). They had a very characteristic hierarchy system in which old soldiers trained newcomers. They had rankings amongst themselves, medical staff, chaplains, even their own justice system. Their most recognisable symbol was the Cross of Burgundy on different backgrounds.
Tercios battled all across Europe with the expansion of the Habsburg house. They fought in Italy, and most famously in the Belgian region of Flanders – there are several monuments in Antwerp hailing the locals who opposed them. Velázquez painted the most famous work of art around the Tercios, La Rendición de Breda – the “Surrender of Breda”, an Italian city conquered in 1625. As world and war changed, their battlefield tactics became obsolete in the 18th century, and they eventually dissolved away, transformed into regiments, as the figure of the pikeman was dropped.
The name Tercios survives in naming the Spanish Navy and Legion units. The historical recreation association 31 Enero Tercios appeared (as far as I have been able to find) around 2020, formed by history professional and amateurs who wanted to remember the Tercios units, organising re-enactments and activities all around the country. Their website is a bit chaotic, and might be slightly problematic with its language at points, but most people just seem to enjoy dressing up, playing with fake weapons, and going home to their phones after they wrap up.
One of the goals of the association is to establish the 31st of January as Tercios Day Día de los Tercios, organising activities and re-enactments throughout the country. It sounded interesting enough so we thought we would sign up the aforementioned day trip… only for it to be cancelled a couple of days later due to general lack of participation. Since there was no forecast of rain or snow, but sun for a change, we thought we could drop by on our own.
There were two main stages for the activities in Madrid: one was Plaza de la Villa (site of the historical town hall), the other Main Square Plaza Mayor. We walked through the latter on our way to the former, and there was absolutely no indication of anything going on. When we arrived at the Plaza de la Villa, they were still setting up camp (literally), so we went to have breakfast somewhere in order to be out of the cold. We had decided to join the “theatre visit” at 11:00, which was difficult as inscriptions were chaotic.
I’m not a guided-visit person, but this was… bad. My parent, who actually likes them, concurs. The “theatre” part came from three people tagging along in period dresses and a two-minute “assassination” in the end, after walking through a number of alleyways and stopping in the most awkward and windy points to see… unrelated buildings. I was completely unable to follow the theoretical plot line of the visit and how it… was any kind of plot, really. I’m still even unclear on who or why was assassinated and their relation to the Tercios.

The visit ended near the Army cathedral Iglesia Catedral de las Fuerzas Armadas, so I asked my parents if they minded stopping by St Michael’s church Iglesia de San Miguel, which had been closed the previous time I had been around. We were able to snoop inside, but just a little, as they were holding mass.

We then headed back towards the Plaza de la Villa, where there was a demonstration of how the pikers would train. This is the kind of thing I like to watch, but my parents don’t, especially in the cold. After a few minutes, they wanted to move on. By the time we reached the Plaza Mayor, the event there had finished and I only managed to get a photo of the ensemble.

We then headed off to a high-end traditional grill Asador de Aranda that my parent wanted to try. I can’t say I’d recommend the place, as they broke my heart. First, the menu promised baked potatoes and the waiter brought microwaved ones. As we were sitting near the actual wood oven, I had really hoped for oven-baked potatoes. The meat was all right, maybe a bit overcooked, and finally the advertised “five-star pudding” was not-at-all stellar. In general, it felt overhyped and overpriced.
After lunch, I debated whether to stay in Madrid or head back with my parents, but the next event on the Día de los Tercios schedule was a parade at 20:00… too long to wait in the cold. Hence, I decided to just make a note in my calendar for 2027, and quietly slip out to see all the re-enactments on my own. Knowing in advance that this event exists, I can keep an eye on it and plan for down time between the different activities.
