Ragnar Lothbrok Family Tree — Lothbrok, Ragnarsson, Rollo and Haraldsson Networks

The Ragnar Lothbrok family tree, without the guesswork

Ragnar Lothbrok is the centre of a family tree that keeps changing shape. He begins as a farmer, sails west, becomes a king, and leaves six sons who spend the rest of the story arguing over what his name is worth. Lagertha, his first wife, builds an earldom of her own. Rollo, his brother, leaves for a Frankish duchy. Aslaug, his second wife, gives him four more sons and a prophecy he cannot control. Harald Finehair wants one Norway and cannot forgive a farmer for getting there first.

This archive treats the Ragnar Lothbrok family tree as data, not decoration. Every parent, spouse, sibling, adoption, mentor and loyalty connection is a named pair in a file. The interactive networks draw those pairs; an image model is never asked to invent a line. The result is a family tree you can check, filter and argue with — which is the only kind of Vikings family tree that makes sense.

The families

The Vikings story is not one tree. It is four separate arguments that share a North Sea. The Lothbrok household asks where the west begins. The Ragnarssons ask who inherits the legend. Rollo asks what a brother owes and whether a man can choose a new country. Harald asks who owns Norway. Each network has its own cast, its own centre and its own way of failing.

The Lothbrok household: a farmer, a shieldmaiden and a boat

Ragnar Lothbrok starts with a farm, a boat and a question about what lies west. Lagertha fights beside him and then rules Hedeby without him. Bjorn is their son, raised between two parents who keep leaving. Gyda is their daughter, and her death in the plague makes the farm feel temporary. Aslaug arrives as a princess of saga and becomes Ragnar's second wife. Floki builds the boats and Helga keeps a home for him. Athelstan, the monk taken from Lindisfarne, becomes Ragnar's interpreter and friend. Torvi, the shieldmaiden, is Lagertha's protégée and later Bjorn's wife.

This network has eleven characters and sixteen explicit edges. The gold parent lines run from Ragnar and Lagertha to Bjorn and Gyda. The rose spouse lines connect Ragnar to Lagertha and Aslaug, and Floki to Helga. The loyalty lines carry the friendships that make the raids possible: Ragnar to Floki, Ragnar to Athelstan, Athelstan to Ecbert. The network is the place to start because every other network depends on it.

The Ragnarssons: six sons and one inheritance

Ragnar has six sons and two family claims. Bjorn is Lagertha's son and the eldest commander. Ubbe, Hvitserk, Sigurd and Ivar are Aslaug's, raised on prophecy and rivalry. After Ragnar's death the brothers raise the Great Heathen Army together, then divide the world it wins. Ivar turns his broken body into a weapon and a kingdom; Ubbe would rather find a new country than rule the old one; Hvitserk keeps choosing a side and losing either way; Sigurd's short life ends in the family's first open fratricide. Torvi and Ingrid are the two women who marry Bjorn and inherit Kattegat's quarrels.

This network has ten characters and twenty-seven explicit edges. Every parent line from Ragnar and Aslaug to the four younger sons is drawn separately, so the half-brother distinction stays visible. The sibling lines are the densest part of the archive: six sons, one generation, and almost every pair has a reason to distrust the other. The spouse lines connect Bjorn to Torvi and Ingrid. The network is a family argument conducted with fleets.

Rollo and Frankia: the brother who chose a duchy

Rollo is Ragnar's older brother and the blunt instrument of the first raids. He stays in Frankia, accepts baptism, marries Princess Gisla and becomes Duke of Normandy. Count Odo is the Frankish commander who defends Paris and turns the siege into a court intrigue. Rouen becomes Rollo's ducal seat and the proof that a Norse warrior can build something permanent outside the family saga. Bjorn is his nephew and student; Floki is the old shipmate who watches him change sides.

This network has nine characters and sixteen explicit edges. The gold sibling line between Rollo and Ragnar is the axis. The rose spouse line to Gisla marks the marriage that seals the Frankish bargain. The loyalty lines to Odo, Floki, Harald and Halfdan show how a defection is negotiated rather than announced. The mentor line from Rollo to Bjorn is the family's attempt to pass on the raid even after the brothers have separated.

Harald Finehair: one Norway, one crown

Harald Finehair is the King of Norway, a monarch who wants to unite the Norse kingdoms under one crown. He is brave, vain and persistent, and his pursuit of Lagertha is both a political ambition and a personal humiliation. Halfdan, his brother, fights the wars Harald declares. Astrid is the shieldmaiden caught between Lagertha, whom she loves, and Harald, whom she marries. Rollo is the other king who understands what Harald wants, and Ivar and Ubbe are the Ragnarsson rivals he must court, use and eventually fight.

This network has nine characters and twenty explicit edges. The gold sibling line between Harald and Halfdan is the Norwegian court's spine. The rose spouse line to Astrid is a political marriage, not a romance. The loyalty lines to Ragnar, Bjorn, Ivar, Ubbe and Rollo are alliances that change with every battle. Astrid's loyalty line to Lagertha is the emotional centre the crown cannot replace.

Seven profile cards

The archive includes seven archival profile cards, each made with the character-profile-card skill: Ragnar Lothbrok, Lagertha, Bjorn Ironside, Rollo, Ivar the Boneless, Harald Finehair and Floki. Each card is a full dossier, not a portrait: age, identity, likes, dislikes, personality, a COMBAT radar chart, a TACTICS radar chart and a five-line character introduction. The cards sit inside their family sections on the hub, so you meet Ragnar, Lagertha and Bjorn with the Lothbrok household; Ivar with the Ragnarssons; Rollo with Frankia; and Harald and Floki with the Norwegian claim.

Five design sheets

Five characters also have full design sheets made with the character-design-sheet skill: Ragnar, Lagertha, Bjorn, Rollo and Ivar. Each sheet shows a front, side and back view at the same scale, four expression heads, detail callouts for boots, hands, belt and signature item, and a small colour palette. The sheets are visual references, not posters: they exist so the same face and costume can be reused across the networks and the poster.

The family poster: seven people, nine edges

The family poster is made with the character-relationship-poster skill. It shows seven named people exactly once: Ragnar, Lagertha, Rollo, Bjorn, Aslaug, Ivar and Harald. It draws exactly nine edges: Ragnar and Lagertha as spouses; Ragnar and Rollo as brothers; Ragnar to Bjorn as parent; Lagertha to Bjorn as parent; Ragnar and Aslaug as spouses; Ragnar to Ivar as parent; Aslaug to Ivar as parent; Bjorn and Ivar as half-brothers; and Ragnar to Harald as rival kings. The poster is a summary, not the source of truth. The source of truth is the data file behind the networks.

Why a network instead of a poster

A poster is a picture of a family tree. A network is the family tree itself. In the four interactive networks, every edge is a source-target pair with a relation type, so a line cannot drift to the wrong person. You can switch views: the whole household, the farm years, the marriages and second wives, the western question, the brothers' war, the Frankish bargain or the Norwegian court. You can click a face and read the relations around it. You can use it on a phone. None of that is possible when an image model is asked to draw a family tree from prose.

The poster still matters, but it has a different job. It is the one-glance summary: seven faces, nine correct edges, a legend that separates bloodline, marriage and loyalty. It is generated from the same cast and the same pairs, so it cannot contradict the networks. That division of labour is the whole point: the networks hold the argument, the poster holds the image.

Frequently asked questions

Is this canon? The family relations follow the television series Vikings and, where relevant, Vikings: Valhalla. Every narrative note is marked show-only because Vikings is a television drama, not an adaptation of a single novel. Where a kinship is also recorded in the Norse sagas or the Anglo-Saxon Chronicle, the note says so, but we do not present saga tradition as a scene the series filmed.

Why are there four networks? A single graph with every character becomes unreadable. Four networks keep each argument legible and let you start from the question you actually have: the first household, the sons, the brother who left, or the king who wanted Norway.

Is Ragnar really the father of all six sons? In the series, yes: Bjorn is the son of Ragnar and Lagertha; Ubbe, Hvitserk, Sigurd and Ivar are the sons of Ragnar and Aslaug. The archive draws the two parent lines separately so the half-brother relationships stay visible.

Are Lagertha and Ragnar still married? No. They are married in the first seasons, then separate when Ragnar takes Aslaug. Lagertha later rules Hedeby in her own right. The network marks the marriage and the separation rather than flattening them into a single line.

Is Rollo Ragnar's brother? In the series, yes, Rollo is Ragnar's older brother. He leaves the family for Frankia, accepts baptism, marries Gisla and becomes Duke of Normandy. The archive treats that defection as a political choice, not a betrayal with one meaning.

Can I read it on a phone? Yes. The networks are built to be dragged, zoomed and tapped. The hub and the archive page reflow to a single column, and the images are served as compressed WebP files.

Open the archive

Start with the hub, then open the Lothbrok network and click a face. If you want the sons' argument, open the Ragnarssons. If you want the brother who left, open Rollo. If you want the other king, open Haraldsson. The poster is there when you need the whole family in one glance.

Every layer of this archive was built with four named skills: relationship-network for the four interactive graphs, character-relationship-poster for the family poster, character-profile-card for the seven dossiers, and character-design-sheet for the five turnaround sheets. The data, the drawings and the pages are separate on purpose, so each one can be checked against the others.
