Town vs Gown in 15th Century Silesia

Medieval cities often had fraught relations with their regional clergy. Many towns at some point called their local bishopric overlord according to Feudal law. But eventually, some forced the episcopal ruler out of town and established their autonomy by acquiring the charter of a free city or free imperial / royal city.

The prelates of the Church, many of whom were from families of the warrior aristocracy, did not take this lying down, and there were many ongoing disputes between burgher and bishop lasting multiple generations. Sometimes these broke out into pitched battles, such as when the town of Strasbourg defeated their prince-archbishop Walter von Geroldseck in an open field battle at Hausbergen in 1262[1], capturing 86 of his knights and killing 1370 of his men; or when the Archbishop of Mainz Adolf II von Nassau sacked and recaptured that city in 1462[2], executing 400 people, exiling many more (including Johannes Gutenberg) and ending the autonomy of that town.

More often these conflicts consisted of endless lawsuits, diplomatic wrangling, occasional raids and kidnappings, and small skirmishes. The prince-bishops also used their unique episcopal powers such as the ability to place individuals or entire communities under interdict or even excommunication. In extreme cases, they might also attempt to invoke the inquisition.

Partly because these rivalries went on for so long, it’s difficult to find comprehensive let alone unbiased histories of the ongoing feuds between town and bishop. But one good if not perfect source is the magisterial history of the cleric, and eventually bishop Jan Długosz of Poland. His ‘annales’ which cover the history of Poland from 965 to his own death in 1480, are not free of bias but are quite thorough, well written, and by the standards of the day, fairly even handed.

From these annals, we find here an interesting example of strife between the citizens of Wrocław (aka Breslau to it’s German-speaking inhabitants, and Vratislav to its Czech overlords) vs their local Bishopric. This lasted from 1337 through 1341, during the reign of bishops, Nankier Kołda (aka Nanker).

The following excerpts from the annals of Jan Długosz[3] cover the key incidents of the conflict:

Wroclaw helps King John of Bohemia ransack the bishop’s cathedral and castle, with the help of wine – From the entry for 1337

The King of Bohemia [King John the Blind], having by intrigue, flattery or promises subjugated the Polish dukedoms in Silesia and illegally occupied the town and duchy of Wroclaw… now plunders the cathedral at Wroclow, which the Silesian dukes endowed. He orders the Bishop and Chapter to surrender its castle at Milicz, and, when Bishop Nanker, a courageous main, disdainfully refuses to obey, the King brings up a powerful force, reinforced by some citizens of Wroclaw, and attacks the castle which was held in the name of the Wroclaw chapter by Henry of Wierzbno the archdeacon. Seeing that it will not be easy to capture it, for the castle has good defenses, and learning that the Archdeacon is an inveterate wine-bibber, he sends him some friendly Silesian knights with bottles of wine in profusion, as a result of which they are eventually able with threats and promises to induce the Archdeacon to evacuate the castle with his entourage.

The Bishop sends letters and messengers to the King, demanding the return of the castle, and when this is refused, imposes an interdict on the whole diocese. Further attempts to obtain the return of the castle are made later, when the King comes to Wroclaw. When these, too, are unsuccessful, the Bishop, ordering all his clergy to accompany him, goes to the King …they find the King in a small room adjacent to the refectory. They knock loudly on the door, and, when the King tells them he is occupied with other matters and cannot give them audience… the Bishop takes hold of his crucifix and says: “By the authority of Almighty God I excommunicate you as a plunderer of Church goods and pronounce you excommunicated in the name of the Father and of the Son and the Holy Ghost.”…

The Bishop leaves Wroclaw and orders all churches in Wroclaw to be closed. Nonetheless the doors of the three parish churches of St. Mary Magdelen, St. Elizabeth and the Holy Ghost are forcibly opened and services are resumed on the orders of the King and the city-fathers. Pope Benedit XII, who is in Avignon, praises the Bishop for what he has done and orders him to persist. He also confirms and increases the penalties imposed on the King and the citizens of Wroclaw, on whom he pronounces anathema.”

Wroclaw sees off the inquisitor – From the entry for 1339

“Bishop Nanker of Wroclaw realizes that sterner measures will be required, if the obstinate rebellion of the citizens and city fathers of Wroclaw is to be quelled, since those taken by their own bishop, and indeed, by the Holy See, have achieved nothing in more than a year; indeed, the situation is getting steadily worse and doing considerable harm to the Church. So, the Bishop summons the Inquisitor of Heretical Faults in the diocese, Brother John of Schwenkenfeld of the Dominicans, a man of blameless and exemplary life, and explains to him the obduracy of the citizens of Wroclaw and requires him to take action against them for disregarding the punishments laid on them Church, thus making themselves suspect of heresy [In therefore, in theory, legally liable to investigation by the inquisitor]

Brother Jan is well acquainted with the misdemeanours of the citizens of Wroclaw and promises to try and exert his authority. He goes to Wroclaw and, one Sunday, from a pulpit set up before the City Hall, speaks to a huge throng, rebukes them for abusing holy places and for their obstinacy and begs them to return to the bosom of the Church. He concludes by challenging them to appear before him the next day and answer the accusations laid against them. When the citizens concerned fail to appear, the Inquisitor, inspired by the Holy Spirit, goes in person to the City Hall and calls upon the city fathers he finds gathered there to delay no longer in returning to the bosom of the Church, for otherwise they will call down upon themselves the wrath of God.

He tells them, too, that he is determined to use all the means his office allows to quell their intransigence [in theory this would include excommunication, torture, execution etc.]. After a long discussion, the Inquisitor concludes that he is getting nowhere and leaves the City Hall pursued by curses, insults and grinding of teeth; indeed, he is lucky not to have been assaulted.”

The old Bishop dies, Wroclaw pays assassins 30 marks to kill the Inquisitor – from the entry for 1341

Bishop Nanker of Wroclaw dies on April 10, apparently suddenly, but it is also said that he was ssecretly killed on the orders of the King of Bohemia [King John, Luxeumburg family, father of Emperor Charles IV, died at Crecy] in retaliation for his public excommunication of the king. The city fathers of Wroclaw are delighted by the death of their bishop and regard this as a victory over the Church. They now go to King John and register against the Wroclaw inquisitor, alleging that he has insulted and condemned them. …

“While spending the night at the Dominican monastery of St. Clement, two thugs come to the Inquisitor’s cell and knock on the door, demanding to be given confession. The Inquisitor is preparing a sermon and tries to put them off, but they tell him that, if he does not listen to them while they still have a spark of contrition left, it will be too late. At this, the Inquisitor emerges, receives three thrusts from their two swords and drops down dead. The King suspects the starosta of having planned the murder with the city council and arrests them, but when they on oath deny their guilt they are released. A year and a half later the two thugs are arrested on another charge and condemned to death. They then confess to the previous crime and tell that they had been bribed by two of the burghers from Wroclaw, who gave them thirty marks for the deed.”

In these excerpts from a fifteenth century history, we can see that while prelates such as bishops wielded extraordinary diplomatic, military, and spiritual power, towns also had many tools at their disposal, and were not afraid to resort to violence to protect their interests. The inquisition was not a common event in the late medieval period, but they did happen. In Wroclaw itself, during a visit by Franciscan arch-zealot and future saint John Capistrano in 1451, the population was whipped into a frenzy and engaged in a ‘bonfire of the vanities’ and a vicious anti-Jewish pogrom at the instigation of the traveling cleric[4].  Such disruptions were not welcomed by town authorities, who could find their own head on a pike as the result, which helps explain the extreme measures they were willing to take, up to and including assassination, to prevent the bishop and his inquisitor from establishing control.

Wrong place, wrong time – The inclusion of strangers into the urban armed forces

Sovereign cities in the Holy Roman Empire had their own military force. To a significant degree, this armed force was composed of the citizens of the town. Citizens therefore knew that if – or more accurately, when – the day came an urban army was needed, they had to take up arms and march to war themselves.[1]. However, in every town, at any given moment there were strangers[2] present. What happened to people who happened to be in the wrong place at the wrong time, in a city preparing to go to war?

This blog entry explores the relation of these strangers to the urban militia. I will do that based on a specific document in the state archive of Basel-Stadt dealing with the strangers in Basel as the town was preparing to enter into military conflict with Habsburg. (fig. 1)

Fig. 1: Staatsarchiv Basel-Stadt, Ratsbücher J 1, Rufbuch I, 1417 – 1459, fol. 156r.

In early 1445, the town of Basel was in acute military danger as tensions between neighbouring Habsburg and Basel ran higher and higher.[3] Soon, the city council made the decision to raise the militia and subsequently called all the male inhabitants of Basel to arms. In contrast, and in addition to previous calls to arms, the government this time decided that strangers currently in town also had to be part of the urban military forces. This decision is recorded in the “Rufbuch”[4]. The “Rufbuch” (book of calls) was one of Basel’s many city books (liber civitatis). However, it represents a special category of city book since the Rufbuch was especially created to document what today would be called public service announcements. The “Rufbuch” consist of laws, admonitions and calls to order the city council had decided in the city hall that were then – literally – called out to the people. In order to do this, a town crier stood on the stairs of the town hall and read the entries of the Rufbuch out loud in the direction of the market square situated right in front of the town hall. (fig. 2) Accordingly, these texts were specifically created to be read out loud, and this influenced their appearance. For example, the text is written in noticeably bigger fond then records meant for reading only. Also, there are conspicuously numerous corrections done to the text, maybe indicating improvements made after previous rounds of reading.

Fig. 2: In the front: town hall with corn market. From here the new order was made public. Excerpt from the Staatsarchiv Basel-Stadt, Merian, Matthäus: Gesamtansicht der Stadt aus der Vogelperspektive von Nordosten, 1615, Kupferstich, BILD 1_291.)

In 1445, the city crier would have cried out this new ruling concerning strangers ordered to join the armed forces to the people gathering in the market square. He announced that the city council had conferred and decided that since there was “vil frömdes volkes” (a lot of strangers) in town, these strangers should join the urban militia. The strangers had to show their willingness to do so by swearing that they would march under the city banner. Subsequently, the strangers were ordered to assign themselves to one of Basel’s 15 guilds. This presented a necessary step to become part of the urban forces, since the guilds made up the town’s basic organisational structure. How serious the government took this new practice is made clear in the declaration that everyone not complying to the order would be treated as an enemy of the town.

Basel was apparently especially in need of men with carts, since the townspeaker was pressed to emphasise that strangers in possession of carts and carriages had to have them in good condition and had to freely offer them up for use. This may be explained by the demands made by the course of this specific war, since Basel’s military forces did not only prepare for short excursions, but for longer expeditions which even included sieges. Such ventures required a certain amount of carts for all the needed goods out into the field and in front of the besieged places. Bounty also had to be ferried back somehow.[5]

The town crier also informed the public, that out in the field the strangers in Basel’s army had to wear a red cross on a white surface, signalling the side they were on. This was the standard of the Swiss Confederation – allies of Basel in this war. The sign was usually worn stitched onto a sleeve.[6]

Unfortunately, the city council does not elaborate who specifically they meant by “vil frömdes volk”. Even though it is somewhat obvious, here it bears emphasising that a town’s population did not only consist of its permanent inhabitants. Indeed, at any given moment in time, Basel would have had a wealth of strangers in town – newcomers from near and far who wanted to settle in as well as mere passer-throughs in form of merchants, travelling artisans, pilgrims etc.

Yet, the constant stream of newcomers and passer-throughs must have reached a remarkable dimension in 1445. The threat of war did not only mobilise armed citizens, but also people who fled from it, mostly rural residents from the wider region who sought the protection of the city walls. Basel therefore would have had more far more people inside its walls than usual. In this regard, there is an enlightening addition made in the Rufbuch fol. 156r, after the actual declaration. In it, the government points out that if people from neighbouring Habsburg land were to flee to Basel, they would be considered enemies and be imprisoned.

At the same time, Basel still hosted the members of the council of Basel including a papal court that was regularly joined by important guests. In 1445, for example, Margaret of Savoy visited her father the pope in Basel on her journey towards her wedding destination, bringing her own court with her.[7]

Clerics and diplomatic guests were not the ones addressed by the new order recorded in the Rufbuch though. We can safely guess that the order rather addressed the men who had arrived fleeing from the countryside and from smaller, more vulnerable towns into the relative safety of the city walls. In times of acute military danger, the municipal government of Basel decided to include these strangers currently residing in Basel into the town’s armed forces. With this move, they increased their fighting power and also, maybe more importantly, they attempted to defuse the perceived threat of the unknown the unusual amount of strangers presented. For the government, the order created an avenue of access and control by constructing a situation where either the strangers let themselves be incorporated into the town’s war efforts or the government could remove them for not subjecting themselves to local law.

[2] In the following, the term “stranger” is understood as either a newcomer from villages or other towns or a passer-through. “Strangers” who did not come from outside, yet who had a sense of “strangerhood” attached to themselves, as for example Jews in central Europe or, to a degree, women, are not part of the following. However their relation to the urban martial community will be a focus point of my dissertation. For the use and meaning of the term “stranger” see Miri Rubin, Cities of Strangers, Making Lives in Medieval Europe, (Cambridge University Press, 2020).
