Frisian women: free and unbound?

Below Saskia Holleman. The reincarnation of Mata Hari, her fellow-citizen. Saskia, born in 1945 in the city of Leeuwarden in province Friesland. Standing naked in milky grasslands with Holstein-Friesian cows. In every detail the scenery you will be immersed into when hiking the Frisian Coast Trail. It is a pamphlet of the former Dutch Pacifist Socialist Party (PSP) for the general-elections campaign in 1971.

Translated the pamphlet says something like: ‘PSP – disarmingly/endearing’. The pamphlet caused quite a rouse at the time. Not for the pacifist’s statement to disarm during the height of the Cold War. No, no real risks there for the Dutch. Combining nudity with politics, however, was a whole different ball game. Certainly a bridge or two too far, in the so-called and self-proclaimed progressive lowlands. Yes, the Netherlands, they really got their priorities straight. It took a Dutch-Somali woman and politician, Ayaan Hirsi Ali, to appreciate the pamphlet fully. That was in 2005. But the lowlands were too small for Ayaan. She left for the United States.

We do not show you this pamphlet in order to (re)start a popular discussion about politics and populism. That would be too easy. Nor do we show this fifty-years-old pamphlet to be punished by Mark Zuckerberg again; author of this post was already banned twice for a week from Facebook after showing this pamphlet of the early ’70s. No, we merely show it to illustrate the topic of our post, namely: Are the women of Frisia free? More precise; did women have a more equal position in (early) Frisian society? Regularly, Frisians claim women always held a strong position in their society. Suggesting Frisians have a more feminine, non-macho culture. Is this true or false?

In this post the term ‘Frisian’ is used for persons born in areas referred to as Frisian at the time they were born, since what is considered and named ‘Frisian’ shifted over time. Yes, Frisian (and therefore Dutch and German partly too) identity is difficult to pin down, and would justify a separate long read. Although, that would be near politics. We will not do that.

Back to the topic of this post.

We can, of course, put an end to the whole discussion whether or not Frisian women held a strong(er) position, by highlighting the statue Ús Mem in the city of Leeuwarden. Ús Mem, ‘our mother’ in Mid-Frisian language, is a statue of a huge Frisian cow. A much praised breed, and sadly nearly extinct nowadays. How weird, and therefore convincing, such a statue might be, it would be too easy for this post to settle the matter this way. Additionally, every scholar only would follow the example of Moses in the desert, and throw his (e-)tablets against this Frisian-cow statue, because such a theory would be unsubstantiated.

Let’s dig a bit deeper.

Gods and names

To stick with idolatry and religion. There is a reoccurring story among Frisians that their tribe name derives from the Germanic goddess Freyja or Freya. A goddess of Norse mythology associated with love, beauty, fertility ànd with war. It nicely would fit for this post, except that we have not found much scientific support for this story. Despite convincing Frisian beauty like Luisa Hartema, Doutsen Kroes, Maike van Grieken, Marloes Horst, Anna Wilken, Fredau Hoekstra, Anne-Marie Lampe, Monique Sluyter, Akke-Marije Marinus, Sylvana van IJsselmuiden, Jane Fonda and, of course, Audrey Hepburn (see featured image of this post).

The only small lead concerning goddess Freyja we could find, are the Roman stone inscriptions at Hadrian’s Wall in Britain. The numerus (i.e. an army unit) of a Frisian chieftain named Hnaudifridius, or in his native language Notfrid, serving the Roman army in the third century, set up an altar that was dedicated to among other the goddess Friagabis, one of the two Alaisiagae deities. Etymologically Freyja might be related to Friagabis, which would make a full circle. But we are not impressed by this theory. Read also our post Groove in the Hearth to read more about pre-medieval goddesses worshiped by the Frisians.

If you are interested to read more about the etymology of the word Frisian read this post of Taaldacht, in Dutch language, about its possible origins. The words Freyja and Frisian turn out not be related. An etymological explanation of the word Frisian that fits the ’70s pamphlet depicting Saskia Holleman, is the Old-Germanic ‘Frisioz’ which could mean ‘free and unbound’.

If you are interested in this Frisian chieftain Notfrid in the Roman army mentioned above, read our post Frisian mercenaries in the Roman army. The same Frisian mercenaries erected a stone pillar dedicated to the thing (also ding, ting or þing), the Germanic assemblies. It is the oldest attestation of the thing in history. Read our post The Thing is… to learn more about these early democrats.

Concerning the Roman Period, it was the Roman historian Tacitus (ca. AD 56-120) who wrote in the first century that in Germanic cultures, contrary to what was customary in the Mediterranean, it was the men who gave the dowry. No jewelry and other vanity goods, by the way. The dowry consisted of cattle, horses and weapons. Also, the dowry remained the bride’s personal property after they had married. Tacitus also wrote that women had the gift of prophecy and were the fortune-tellers. Illustrating women had a central position within the pre-Germanic pagan believes.

A modest argument about the strong(er) position of Frisian women that can be derived from Freyja, is that this goddess wore fibulae ‘brooches’ similar to those magnificent pieces found at for example the terp (i.e. artificial settlement mound) of Wiewerd and, of course, at the terp of Wijnaldum. Both locations situated in province Friesland. We know this thanks to a silver pendant depicting Freyja with this specific type of fibula, found in Östergötland in the south of Sweden. Read also our post Ornament of the Gods found in a mound of clay to learn about this piece of history. Thus, it were Frisian women, not macho kings or otherwise big men, who were the proud owners of these very exquisite fibulae, matching the quality of the Anglo-Saxon jewelry found in Sutton Hoo in England.

fibula Hogebeintum
fibula of the terp Hogebeintum, ca. AD 650

A prominent Frisian god who was worshiped at the time of these type of fibulae were crafted, was the god Foseti also written Forseti. It was worshiped at Fositesland. The Anglo-Saxon Saint Willibrord, Apostle of the Frisians, visited Fositesland in the beginning of the seventh century. Fositesland is generally identified as the present-day island Heligoland or Helgoland, in the German Bight in the North Sea. An island named after the Frisian god Foseti, meaning ‘chairman’, and still similar to the Mid-Frisian verb foarsitte. However, the god Foseti was mostly portrayed as a man, and associated with law and justice. Boring, boring. Not giving us any leads to answer the burning question of this post.

Surprisingly, in Norway near Oslo the toponym Forsetlund exists, despite the fact Foseti was not a Norwegian god at all. The Old-Norwegian name Forseti is therefore probably derived from the Frisian name Fo(r)seti. Were it Frisian immigrants who introduced Foseti to the Norwegians?

There is another modest indication women of Germanic cultures were relatively independent. Names given to both men ánd women referred to bold and brave animals and weapons. Obviously, women, like men, were expected to be strong and powerful too. The fact several Viking warrior graves turned out to be not of men but of women, supports this idea. Tacitus too wrote that women in the Germanic cultures were expected to be brave and to stand side by side with her man during battle. Probably, battle was more a matter of families than that of bands of men, during the Roman Period anyway. Women fighting, or at least at the edge of the battlefield to support them with food, new lead sling-bullets, encourage and treat them, et cetera.


Early-medieval times do give us another hint woman might have a relative equal position, although a heavily disputed one. Old-Frisian law namely gave women the right to kill an infant. At the end of the eighth century, part of Frisian customary law was codified known as the Lex Frisionum. The codex had jurisdiction over the area between Sincfala (i.e. inlet the Zwin) in present-day Belgium, and the River Weser in the northwest of present-day Germany. Title V of the Lex Frisionum states:

de Hominibus qui sine compositione occidi possunt […] et infans ab utera sublatus et enecatus a matre

of the people who may be killed without a fine, are infants. The infant may be strangled by the mother and only if the infant was forced out the uterus

Some historians plea for a bit different understanding of this, indeed, difficult to understand law. They argue that in general it was at the discretion of the mother to let her infant die, as long as it had not been fed yet. This would align with the ninth-century Vita Liudgeri where this practice in Frisia is mentioned. In this document the mother of Saint Ludger, named Liafburch, was saved as a newborn from being killed by her grandmother because neighbors put honey on the lips of little Liafburch. Having received nutrition, no longer infant Liafburch could be killed by her mother without being punished. Therefore, Ludger could be born later. He in his turn, would convert the Frisians to Christianity, et cetera. The rest is history. For more, read our post Liudger, the first Frisian apostle.

We leave the precise historical and linguistic discussions aside, and conclude at this place there were evidently circumstances which could justify killing an infant and, moreover, that this was the authority of women. Not that of men. They had not this right. To address the reader’s dismay, this practice is not as barbaric and inconceivable as you might think at first. By no means it was comparable with Saturn devouring his son painted by Goya. Instead, harsh and tough decisions had to be made in the past. A time without social healthcare, not even your basic Obama Care. A community had to consider, for example, whether or not a disformed child could be fed and raised. Lastly, Frisian law was different compared with that of its Scandinavian neighbors. There, it was the men who had the right to kill a newborn infant, and not the women.

Another distinctive difference with other early-medieval Germanic cultures can be found in the Lex Frisionum when compared to the region, namely that a weregeld, also called blood money, for killing a woman was the same as that for killing a man, of the same social status. The weregeld for both was 50 Byzantine golden solidi or ca. 1,7 kilogram of fine silver. One cow was worth one solidus, according to the Lex Ribuaria. You can do the math if you wanted to pay a weregeld with cattle. In other Germanic cultures, you had to pay a bigger fine for killing a woman than for killing a man. Even three times as much. The logic behind it might be that women were more ‘precious’ with regard to offspring, and they had in general a shorter life expectancy, mainly because of death during child bed. However, in East Anglia, like in Frisia, freeborn women and freemen had the same ‘value’ in fine silver. If interested to learn everything about weregelds, read our post You killed a man? That’ll be 1 weregeld, please.

We would suggest not to interpret all this in a way women were of less value in the Frisian and Anglo-Saxon cultures, when compared to other Germanic tribes. Instead, it expressed women were regarded (more) equal to man, and not primarily seen as economic value. Or, another way of looking at it, it might indicate that in Frisia and in England women had a lower mortality rate during child birth than elsewhere. For a society with a high mortality in general, it is important for its survival to have many women and children, since they in general have a high(er) mortality rate.

Leaving the horror, legal texts and codices behind us, the era of the Lex Frisionum was in fact definable for the position of women in society. Let us explain this through ‘The life of Beitske’.

Beitske of Hogebeintum

The remains of Beitske were found during excavations of the terp of the village Hogebeintum, in the north of province Friesland. Beitske is not named after the successful Frisian racing driver Beitske Visser. No, her name is a reference to the wooden tree-coffin she was found in. Sorry twice, Beitske Visser! The Fries Museum in Leeuwarden simply did a poll, and the name Beitske was the most popular one. Also, in 2015 Maja d’Hollosy reconstructed her face in a very beautiful way (see image below). “All nice to know, but what has all this to do with this topic?” you might think. The following two things of Beitske are of need to know for the burning question of this post.

Beitske of Hogebeintum c.AD 650

Firstly, Beitske’s inhumation was exceptional because she was buried. Above that, she was buried in a tree trunk. The wood used was expensive oak. Burying the dead was for long, in any case till the Migration Period, exceptional within the salt-marsh cultures of the Wadden Sea. Archaeologists consider the most common inhumation practice, leaving the body on the salt marshes for scavengers. Above, burying deceased in a coffin is exceptional. Wood was scarce at the barren, treeless tidal marshlands. Let alone oak wood. Furthermore, she wore a necklace of shells and amber. Taken everything together, this indicates we are dealing with a woman of certain prestige. If you want to know more about early burial practices, read our post How to bury your mother-in-law. In 2018, another interesting early-medieval coffin grave of a woman of Frisia was found, read our post Notre dame of Grou. Not a proud looking Beitske, but a heavily disformed woman.

Secondly, the age of Beitske. She was around fifty years old when she died. A considerable age in those days. However, the period she lived in, is truly relevant. This is the seventh century. Considering her personal age, Beitske lived ca. 650.

A lot of expenses and efforts for an old woman

There are similarities with other North Sea, southern Scandinavian, cultures. Grave finds of older women of prestige have been found of Vikings in southern Sweden, for example. But also the boat burial of Solleveld, close to modern The Hague, is relevant, because the person buried probably was a woman. The grave is dated the first half of the seventh century. Read more about this unique grave in our post Rowing the souls of the dead to Britain: the ferryman of Solleveld.

The time Beitske lived, Frisia was at the height of its power. Maybe Beitske even knew or had seen king Aldgisl or king Radbod, although they might have been overkings of a southwestern kingdom (West Frisia), and Beitske was ruled by a different Frisian king of the northwest. Nevertheless, certainly she must have heard of one of them. It was the period the Frisians controlled the supra-regional trade at the wider North Sea, and had trading networks and settlements stretching from the British Isles, including ports of York and London, to Denmark, southern Norway, eastern Sweden, into the Baltic Sea and deep into Frankish lands (i.e. Cologne, Worms and Paris, to name a few cities). Also, the Frisians still held control over their trade emporium Dorestat at the lower region of the River Rhine, the biggest settlement of northwestern Europe that time. Some historians refer to this period as the First Golden Age of the Low Countries, a period the Frisians were a dominant seafaring nation (Van der Tuuk 2011). Not fishing but trading, to be clear. If you want to have a more detailed picture of the magnitude of the Frisian free trade, read our post Porcupines bore U.S. bucks.

The social structure of the Frisian society in the Early Middle Ages, was built around the family. Living in small terp villages along the southern coast of the North Sea from West Flanders to the south of Jutland. It was a fairly equal society, in the sense there were no real centrally led power structures, despite nobiles and (elected?) kings and overkings did exist. Besides trade, the Frisians were livestock farmers too. The Frisians at the Wadden Sea coast held mainly sheep and cows on the salt marshes. Some crop production maybe too, salt-resistant crops like flax. These were protected against the sea by low summer dikes.

So, the distinctive element out of the above is that the Frisians were agrarians and sea traders. The season to sail and for trade was from spring to the end of summer. We may assume, the management of the farm was (partly) left to the women. It all was relevant for the social position of women. It goes much too far to say women were equal to men. Not at all. But they had big responsibilities and steered the house and farm for months during the absence of their trading men overseas. No child daycare. Preparing the house for winter even. Several historians argue this laid the foundation for a strong(er) position of women compared with other surrounding cultures, or better, with southern Europe.

In the seventeenth and eighteenth centuries this history repeated itself at the Frisian Wadden Sea islands, notably in Nordfriesland, when whaling had become an important economic activity. Nearly all adult men were at sea and it was the women who took care of the farmstead. Read our post Happy Hunting Grounds in the Arctic. In general you can say, early societies living at and from the sea, whether trade of fishing, inevitable led to temporarily ‘seperation’ of men and women. This might have stimulated a more equal position of women and men. And who knows, working at the unpredicatble sea might have led to a relative higher mortality rate of men, matching that of women due to death in childbirth, which also might have stimulated a more equal position, reflected in the weregeld amounts as described earlier.

Around the ninth century, when Christianity was first introduced in Frisia, the new religion’s more liberal status for women including marriage as a matter of consent, connected very well with the already existing cultural and legal position of the ‘sea-culture women’ of the north. A vast collection of late and high-medieval law codices and legal textst of Frisia has been preserved. According to these laws, women had the right to divorce from her husband, and was free to choose the man she wanted. Also, women were legally entitled to inherit property and to invest in a business, or to personally run one.

The Frisian custom of ‘knot cloths’ which still existed in the seventeenth century, fitted within this old tradition. In a small piece of cloth some coins were placed with a loosely knotted knot. This was offered with the proposal by the boy. If the girl accepted the money or gift, she drew the knot tighter, after which they were engaged. In the sixteenth century, the custom of a ‘knottekistje’ existed. A small case that contained silver pennies and money that was given to the girl with the offer of marriage. If she accepted, they were engaged. In short, show me the money, was what she demanded.

When looking at medieval monastery life in high-medieval Frisia, the Knights Hospitaller of Saint John had a strong presence, comparable with other regions in Europe during the period of the Crusades. Around the year 1300 there were more than twenty houses with a convent in Frisia. Interestingly, and totally different from the houses of the Knight Hospitaller of Saint John elsewhere in Europe, was that nearly all of the Saint John houses in Frisia were inhabited by women, mainly lay-sisters. These houses needed to be profitable, and thus the women must have been economic active within the community. The Saint John Order represented about a fourth of total of monastic houses in Frisia. The other three quarters of the houses and monasteries belonged to the orders of the Augustinians, of Saint Benedict, of the Cistercians, of the Premonstratensians and a few to the Teutonic Order. Most of these monasteries were inhabited by women too, both choir nuns (or cloistered nuns) and lay-sisters.

Let’s step back to the Early Middle Ages again. A beautiful ninth-century story has been preserved. It is about a women living in a Frisian colony in Birka in present-day southern Sweden. An old, Frisian woman, whose name was Frideburg, requested her daughter Catla to make the journey to the emporium of Dorestat in the River Rhine area of Frisia after her death, in order to distribute her fortune among the church and the poor. Her daughter did what was requested. She traveled all the way to Dorestat, present-day Wijk bij Duurstede in the Netherlands, and distributed the wealth of her mother (Lebecq 1992).

Another interesting story around 800 was that of Saint Ludger, when he was in Frisia to convert the people to Christendom. In the village Helewyret, present-day Helwerd in province Groningen, Saint Ludger met the beloved blind bard named Bernlef. Bernlef was introduced to Saint Ludger by a woman named Meinsuit. A mysterious woman. Who was she and why was it a woman who introduced Bernlef, and not a noble or a man of stature? A visit of an authority like Ludger was not your regular thing, those days. Want to know more about Meinsuit or the blind bard Bernlef, read our post One of history’s enlightening hikes, that of Bernlef.

To continue our argument, in common with the Anglo-Saxons, women played a vital role in preventing, stemming and ending conflicts between tribes. This because of the fact they often were married into rival kin-groups. During tensions or violence between groups, these women had a personal interest and natural strong position between the rivaling kin-groups to intermediate. This position is also illustrated in the Old-English epic poem Beowulf. Queen Hildeburg, who was married to King Finn of Frisia, is the ‘chief mourner’ after her son was killed during the battle between her own Danish kin and the Frisians. Her son, of course, being half Danish and half Frisian.


So, there you have it. Everything put together a modest case can be made of a historical, more independent position of women in Frisian culture being for a long time part of the medieval North-Sea culture. A culture therefore partly inherited by the northern Dutch and northern Germans too. No reason to praise ourselves, by the way. There was probably no equality. Maybe the position of women can best be described with the Old-English Exeter Book poem Maxims I of around the year 1100. The poem tells about Frisian women taking care of everything at the farmstead while their men are at sea for months. But when their (smelly) men return these women assume a caring role.

Scip sceal genægled, scield ge-bundan, léoht linda bord, léof will-cuma, Frísan wífe, þonne flota standeþ; biþ his čéol cumen and hire čeorl to hám, ágen ǽt-giefa, and héo hine inn laðaþ, wæsceþ his wárig hrægl and him seleþ wæde níewe, lihþ him on lande þæs his lufu bǽdeþ. (Exeter Book – Maxims I)

Ships shall be nailed, shields bound, | of light linden-board, her love a welcome guest, | to a Frisian’s wife, when his floating ship stands docked; | His ship will come and her man comes home, | her own provider, and she will call him inside, | wash his worn clothes and wrap him in new robes, | lower to him, landed, what his love bids.

A similar role one can find (again) in the epic Beowulf how queens poured the mead in the cups of the warriors guests and gave gifts to her warrior guests in the hall of her king.

Centuries later, during the Dutch Republic, foreigners were still amazed how freely women in ‘Holland’ were, both physically to travel and economically. Yes, even disapproval by foreigners of the liberty women enjoyed in the seventeenth century. Marriage in the Republic, for example, was already based on partnership and mutual duties and responsibilities. Dutch women had the legal right to marry with a prenuptial agreement. In contrast to English women, Dutch women could own property. They also inherited equal shares with male heirs. After marriage, they had equal share over the property. Women were also actively involded in economic activities, including international trade even (Venema 2003). And, it was the university of Franeker in province Friesland that already admitted female students at the start of the eighteenth century, whilst everywhere else in the Dutch Republic, and later the Netherlands, women had to wait until the year 1871 before they were allowed to go to College. England had fallen behind. Oxford allowed the first women in 1920.

To finish our argument with an artistic and happy note, it was the famous painter Picasso who visited region Westfriesland, and who was impressed by the women of ‘Holland’. Also, how tall they were. Surprise surprise, he might even have had an affair with one. And, judge for yourself. Appear the three women below as painted by Picasso, to be of the obedient kind?

women of West Friesland Picasso
Les Trois Hollandaises, Picasso, 1905


Before we round up; who were the other three women whose images we presented at the start of this post?

Sjoukje Maria Diderika Bokma de Boer (1860-1939) born in Nes (island of Ameland, province Friesland, the Netherlands) better known as Nienke van Hichtum. She was married to the famous Frisian socialist politician Pieter Jelles Troelstra. Actually that was not her biggest achievement. She herself was a prominent socialist, advocated for the Frisian language, and above all was a famous writer. Her children book ‘Afke’s Tiental’ (translated: Afke’s Ten, 1902) has made her famous till this very day.

Recha Schweitzer (1892-1984) born in Norden (region Ostfriesland, Germany). She was a strong and important advocate of Jewish diaspora rights, already before the Second World War. With her organization Youth Aliyah she saved thousands of young Jewish lives during the war. She fled to Israel in 1941. Later in life she supported the Jewish opera. In 1981 she received the Israel Prize, finally.

Margaretha Geertruida Zelle (1876-1917) from Leeuwarden (province Friesland, the Netherlands) and better known as Mata Hari. She was not an idealist or activist and Recha Schweitzer might have had her thoughts about her. Nevertheless, Margaretha was a remarkable independent woman. An exotic dancer, a courtesan, beautiful, free en wild. And, sentenced to death for spying for the Germans. In 1910 she was shot by the French. Until this day, her life and personality is intriguing. As it was for example for the famous American Hollywood actor David Carradine in the ’70s. If you want to know more, read the posts of Hanneke Boonstra about Mata Hari.

What about Saksia Holleman? Well, she was not even aware of the fact the political party PSP stole her picture and used it for their general election campaign. As socialists, why should they? She saw the pamphlets, she sued, she won. After that, the hippie she was, she appeared naked again in the musical Hair in the ’70s, played a role in a soft porn movie Wet Dreams, and performed as a dancer in the Sleewijk Revue of the Dutch theater producer René Sleeswijk. She even played in the first movie of Martin Scorsese: Who’s that knocking on my door/I call first. In this movie, she appeared in an erotic dream of Harvey Keitel. Find here the link to the erotic fragment of this movie, so ’70s. All in all, a life very comparable with her fellow-citizen Mata Hari a century before.

Saskia Holleman on the day of the shoot, near Nootdorp – 1971

Eventually, in 1979, Saskia stopped following Mata Hari’s footsteps, and followed those of the old Frisian god Foseti. Indeed, she became a lawyer. Boring, boring. In 2013 she died, sixty-eight years young.

Have fun walking the endless grasslands of the Frisia Coast Trail, and do pay respect to its strong and tall women.

Note - All the publicity on Mata Hari in the Netherlands in 2017 triggered this post, thanks to writer Shipman. Her book about the life of Mata Hari was published this year in the Dutch language.
