Outlawed and Feared: Seiðr in the Law

Let’s be real. Seiðr scared people.

Not just because of what it could do, but because of who wielded it. The staff. The voice. The presence of a woman speaking fate into a room. It crossed boundaries most people didn’t dare name out loud. Seiðr wasn’t quaint magic. It was unruly, effective, and sometimes lethal. Powerful enough that kings wanted it near them, but not on them. Leaders used it. Then outlawed it. Again and again. This isn’t theory. This is written into law.

​

The Law Spoke Loud

In early Christianized Norway, the laws of King Magnus the Good include direct bans on Seiðr. Not vague morality clauses. These were explicit charges. Performing Seiðr could result in exile, property loss, or worse. The law didn’t just name the act, it named the fear.

In Iceland’s Grágás law code, similar charges appear. Both men and women could be prosecuted for harmful magic, for calling up spirits, or for shape-shifting. The consequences were rarely light. Fines were possible, but many of these charges led to full outlawing. In medieval Icelandic law, to be outlawed was to be erased from society. No protection. No community. No return.

You can find these references in Jenny Jochens’ Old Norse Images of Women, as well as in translated versions of the Grágás codes. They are not symbolic gestures. They are state-sanctioned reactions to a spiritual practice that would not die quietly.

A Weapon of Gender

For men, practicing Seiðr carried a second danger—the accusation of ergi. This Old Norse word doesn’t translate cleanly. It implies unmanliness, sexual deviance, passive weakness, or a break from expected gender norms. It was one of the most serious insults in Norse society. To accuse a man of ergi was to question his entire identity and fitness to lead.

​

Practicing Seiðr brought that risk. Even Óðinn, the highest god, was said to have learned Seiðr from Freyja, and some sagas hint at the shame he carried for it. Not because it didn’t work. But because it placed him in the role of a woman. And that inversion frightened people. In many ways, Seiðr was feared not just as a form of power, but as a form of social disruption. It didn’t just bend the rules. It questioned who got to make them.

Not Just a Christian Problem

This didn’t begin with the witch-hunts of early modern Europe. Long before those trials, women across northern cultures were being silenced or cast out for roles that once held authority.

Among the Sámi, Finnic, and Kven cultures, we see evidence of female spiritual specialists, respected in some places, ridiculed in others. As Norse culture absorbed Christian influence, those roles shifted. Sacred titles became suspicious. Spirit-speaking became heresy. What had once been seen as ancestral or community-based became associated with demons and deviance. The change was gradual, but total. What had been sacred became dangerous. And those who continued to walk that path had to do it in silence.

​

The Thread Didn’t Break

Still, Seiðr did not vanish. It changed shape. People whispered instead of singing. They buried their staffs and covered their names. They passed down fragments in lullabies, in charms, in the things they did without ever saying why.

Because you can outlaw a person. You can criminalize a practice. But you can’t erase a thread once it’s been woven into the body. Seiðr survived not because it was accepted. It survived because it mattered.
