Part I: Rediscovering the 1541 Marxbrüder Coat of Arms

Half a millennium ago, the Imperial City of Frankfurt hosted a curious society known as Masters of the Long Sword, or Marxbrüder. This was the world’s first fencing guild. Its members followed a somewhat formalized curriculum in fencing with various weapons – most notably the long sword – and could earn the title Master of the (Long) Sword, allowing them to teach students for a fee and gain a highly respected qualification in martial arts.

This article assumes a basic familiarity with the Marxbrüder and will not revisit their general history in detail. Instead, it focuses on a particularly niche yet fascinating aspect of their story: their noble coat of arms. Subsequent articles will delve into their broader history and sites in Frankfurt that preserve their legacy.

For those unfamiliar, here’s a mini “lore dump” explaining what made the Marxbrüder remarkable and why they remain shrouded in myth in the historical fencing community:

• They were world’s first fencing guild, founded sometime in the 15^th century.
• Granted by the Emperor, they held a de jure monopoly on teaching fencing in the Holy Roman Empire for around a century, until the rival Federfechter guild in Prague received a similar privilege, creating a duopoly.
• For several centuries, they ran a decentralized civilian organization with a semi-democratic structure,spanning from today’s Kaliningrad to Basel, and meeting in Frankfurt twice a year during trade fairs – which often required several weeks of travel.
• Members who completed the curriculum were awarded a certificate of sword mastery, a recognized honour conferring martial recognition and social standing for civilians.
• Several Marxbrüder rose to prominence, including probable early member Hans Talhoffer, renowned fencing master and author; Onophrius Sokh, imperial bodyguard; and Hans Keesebrod, master builder and politician (whose name somewhat amusingly translates to “cheese sandwich”).

The guild received its formal privileges from the Holy Roman Emperors, beginning with Frederick III on 20 August 1487. These privileges were subsequently renewed and expanded by each emperor up to Leopold I in 1670. A full list of the thirteen Imperial privileges can be found in Schaer (1901).

A Coat of Arms Gone Missing

To this day, all Imperial privileges lie beneath the city of Frankfurt in the depth magazine of the city archive – except for two: Strangely enough, the centerpiece of the convolute is missing: the 1541 issuance of a noble coat of arms by Charles V in Regensburg, along with its 1670 augmentation by Leopold I in Vienna. These two documents are especially significant because they grant a civilian organization the right to bear a noble coat of arms. Moreover, they contain the long-lost Marxbrüder coat of arms, whose appearance remains uncertain to this day.

Hold on, but I saw it on Wikipedia? True, two versions of the arms circulate through the internet. However, there’s problems with them:

1. They are of unknown provenance, which is a convoluted way to say we don’t know their source or veracity.
2. More pressingly, they aren’t the Marxbrüder Coat of Arms. At least neither the original version issued by Charles V in 1541, nor the version augmented 1670 by Leopold I in correct tincture (color). They merely are monochrome copies of what appears to be the augmented arms, created by unknown artists. Version 2 features a monogram AC or AE, but we don’t know what name that stands for. And, most critically, the actual coats of arms along with their letters of privilege continue to be lost.

The Hunt Begins: Searching for the 1541 Imperial Privilege

An unsatisfying interim conclusion, to say the least. I have little patience for loose ends, so I set out on a treasure hunt, beginning with the original coat of arms issued by Charles V. In the age of digital archives, how hard could it be? All I had to do was comb through the databases of Frankfurt, Regensburg, Nuremberg, Augsburg, Vienna, Breslau, Prague, … You get the idea. The decentralized nature of the Marxbrüder guild coupled with the fragmented nature of the Holy Roman Empire itself (further complicated by several major wars) made it entirely plausible that the charter could have ended up in any number of cities across what is now Germany, Austria, Switzerland, the Netherlands, the Czech Republic, or Poland.

Countless (and late) hours, I spammed central European archive information systems and conventional search machines with keywords I hoped would lead me to the letters (e.g., “Marxbrüder” and “Charles V” and “1541” etc.). I’m acquainted to falling into research rabbit holes, but this time, I found myself nursing a quiet grudge against the early modern culprit who dared to remove the privileges from their rightful place. They could’ve at least returned them after they were done showing off. Ironically, the guild’s statutes from the late 15^th century are crystal clear: anyone borrowing a copy of the privileges was bound by oath to return them. Evidently, our anonymous eternal lender was unmoved by such formalities.

A Glimmer in Gießen

After yet another exhaustive search, I came across a curious document in the charter collection of the University of Gießen: a 1541 letter of privilege issued by Emperor Charles V in Regensburg to certain “Masters of the Sword”. Could this be the elusive privilege that first granted the Marxbrüder their coat of arms?

My heart leapt – this had to be it. Opening with a solemn intitulatio, rendered in the ornate chancery script typical for imperial charters, the letter certainly looked the part:

We, Charles the Fifth, by grace of God Roman Emperor, ever the augmenter of the Empire, and King in Germany, of Castile, Aragon, León, both Siciles, Jerusalem, Hungary, Dalmatia, Croatia, Navarre, Granada, Toledo, Valencia, Gaul, Ma[llorca] …

Although switching to a more prophane cursive, the scribe took the due time to enumerate five further lines of titles, culminating in:

Lord in Friesland, in the Windic March, at Portenau, Biscaya, at Molin, at Salins, at Tripoli and Mecheln, etc.

Upong examining the facsimile more closely, however, my excitement slowly gave way to disbelief: The central space that should have contained the arms – was blank. Empty. Had certain Marxbrüder not only relocated the privilege from Frankfurt without returning it, but also dared to steal the coat of arms itself? If so, where had it gone? Into some private collection?

Having accepted the reality that the original arms may be lost forever, I turned to transcription. Perhaps, somewhere in the text, a blazon remained – a formal description of the heraldic figures and tinctures that once adorned the page.

For brevity, I’ll omit the full transcription here (though the Appendix contains more) and will instead highlight the relevant passage beginning at line 13:

[We grant the masters] of the sword and their successors this coat of arms and crest as described below: a black shield whose bottom shows three yellow mountains, at the center of the shield a yellow lion with wings, above the head a halo, with its hindlegs on the mountains, and holding in its left front claw a sword upright. And above the shield an open helmet, on the helmet a golden crown, on the crown a yellow lion with wings, above the head a halo, and holding in its left a sword upright.

So, while the augmented arms as we know them seemed to feature a quartered shield depicting a similar lion in fields 1 and 4 and on its crest, the original arms focused on just the lion. We now also know the tincture: The shield was black and the lion was golden.

Amidst deciphering the scribe’s scrawl – made even more challenging by deep fold marks in the parchment and brownish spots from ink oxidation – I developed an egregious idea: What if this wasn’t the original letter of privilege at all, but merely a copy, sans the coat of arms? After all, we know that several such vidimi exist, including in Frankfurt. The hypothesis that this is a verbatim copy of the original letter, gave me fresh ammunition: a wealth of new keywords for further archival research. Most importantly, I now knew that, in the letter, the guild wasn’t called “Marxbrüder” (Brotherhood of St. Marc) or similar, but simply “Meister des Schwerts” or “Masters of the Sword”.

A Breakthrough in Basel?

Armed with this insight, I was able to pinpoint what I believed to be another copy of the privilege – this time in Basel. Unlike the Gießen letter, this one lacked even a digital facsimile. I had to rely on the metadata (“Charles V”, “1541”, and “Masters of the Sword”) to deduce that his might be the document I had been chasing for months.

I contacted the Basel City Archive and requested a digital high-resolution digital facsimile. Their reply was prompt and gracious: it would be provided for a small fee, though the 500-year-old letter would first need restoration, which might take some time.

Mindful of their time and effort, I asked if, by any chance, this letter contained a small depiction of a coat of arms in the center. If not, there would be no need to proceed further.

The archivist confirmed that this was the case. Delighted, I paid the fee and exercised patience for another couple of days (which, in the grander scheme of things, didn’t matter anymore). And then, I received it: The original Marxbrüder coat of arms, issued by Holy Roman Emperor Charles V on 13 May 1541 in Regensburg. Below, I attach the high-resolution reproduction I received.

A Close Inspection of the 1541 Privilege

Different to the Gießen vidimus, which is penned mostly in a hasty cursive, this original privilege is rendered entirely in chancery script, lavishly illuminated with gold that has since weathered into verdigris. At its heart shines a candy-colored coat of arms, once again adorned with opulent golden diapering. Beyond the details provided in the blazon, we now discern that the mantling is black and gold (heraldically described as sable and or), and that the shield is flanked by two supporters: golden lions with forked tails, standing upon a patch of naturalistic grass.

For the heraldically inclined, I’m attaching my attempt of a blazon. In case you’re unfamiliar, a blazon is a formulaic description of a coat of arms written in heraldic jargon, designed so that someone could recreate the arms without ever seeing them. The syntax is somewhat unusual, and colors are traditionally given in French.

• Shield: Sable, a rampant lion of St. Mark Or with a longsword in its left, upon a trimount Or.
• Mantling: Sable and Or.
• Helmet: Open.
• Crest: A rampant lion of St. Mark Or with a longsword in its left.
• Supporters: Two lions Or upon grass proper.

The text emphasizes the guild’s longstanding service, loyalty, and virtue in martial matters and its elevated role within the Empire. Charles V elevated the guild’s civic status and allowed its members and descendants to enjoy legal and social privileges, including the right to bear and display the arms freely, exercise certain judicial rights, and participate in both martial and ceremonial functions with recognized honor. A full transcript and translation are contained in the Appendix.

The charter’s edges bear visible signs of age and repeated handling. Most conspicuous is the vacant space at the lower margin, where signature and seal once resided. A pronounced dark streak cuts across the center and through the arms, likely the result of water damage incurred during storage.

Yet despite these traces of centuries, the charter’s magnificence endures. Its artistry and heraldic detail continue to command attention, and the wear it carries does little to diminish its lasting grandeur.

Civic Identity and the Marxbrüder Legacy

This rediscovery offers more than aesthetic or archival value – it deepens our understanding of the civic identity of Frankfurt and the Holy Roman Empire.
The richly detailed coat of arms, now revealed in full tincture, sheds light on the Marxbrüder’s iconography while affirming their elevated status and imperial recognition. For heraldry, it presents a notably complete and imperially sanctioned guild armorial charter, rare in both its preservation and detail. And for Frankfurt’s cultural history, it evokes a moment when civic ambition, bolstered by martial skill and political sway, began appropriating the symbols and status once reserved for nobility. Such charters were not merely administrative, but performative declarations of prestige and belonging.

This charter also came to light thanks to the exemplary support of the State Archive of the Canton of Basel-Stadt. From my initial inquiry to the delivery of the reproduction, the entire process (including restoration and high-resolution digitization) was completed within days. The staff were not only exceptionally helpful, they also uploaded the high-resolution digital reproduction I had ordered to their archive database, where it now is accessible for free to anyone: Wappenbrief Karl V. für die Meister des Schwerts
I warmly recommend visiting this page and viewing the document for yourself, ideally on a large, high-resolution display.

Looking Ahead: The Augmented Arms of 1670

I am thrilled to have rediscovered the lost Marxbrüder coat of arms from 1541 and will be sharing more in the coming weeks. The next article will focus on the 1670 augmented version by Leopold I. Stay tuned!
