What Is Dynastiae

What Is Genealogy

Genealogy is the study of family ties between people, built on the kinship and affinity that connects them. Who was related to whom, how one family joined another through marriage across generations. For European dynasties, genealogy isn't an academic curiosity — it's the key to understanding political history itself: royal successions, wars of inheritance, alliances sealed by marriage all came down to exactly who was related to whom, and how closely.

The problem with classic sources — encyclopedias, articles, even most genealogy sites — is that they present kinship in fragments: a separate entry for one person, a separate one for another, leaving the reader to piece together how they connect, if they connect at all. Dynastiae builds this differently — as one searchable structure where every person is part of a larger, connected whole, not a standalone article.

Family Tree vs. Genealogical Graph

The classic "family tree" is a good metaphor for a straight line: an ancestor at the top, descendants branching downward. But real families — European dynasties especially — aren't trees. They're a dense web of connections: cousins married cousins, dynasties merged through political marriages, and one person could descend from two different, seemingly unrelated houses at once. A tree, as a structure, has no cycles — every node has exactly one parent. Real dynastic kinship is full of exactly those cycles: the same ancestor can appear in a person's line more than once, through entirely different branches.

That's why Dynastiae represents its data as a graph, not a tree: people and marriages form one connected network, showing who is whose parent, child, or spouse. A graph can show what a tree simply can't — that the ruler of one country and the ruler of a neighboring one could be cousins through one line and brothers-in-law through another, at the same time. Side branches of the same dynasty are grouped together with the main line on the graph, so it's immediately clear they're still one house, not a separate one. Dynastiae's interactive graph can be expanded step by step — from any one person to their parents, children, or spouses — building a view exactly as wide as you need, instead of a flat diagram someone else decided the shape of in advance.

What Dynastiae Is

Dynastiae is a free genealogical database of European dynasties, built around an interactive graph rather than static articles. Every person, dynasty, and title has its own page with full data and links to every connected figure — but the real strength of the app shows up in the graph: start from any one person and expand their parents, children, or spouses, building a live view of the whole network of connections directly in your browser, no page reloads required.

Dynastiae doesn't try to replace an encyclopedia. Instead of long biographical write-ups of individual people, it focuses on their place in the network of family ties. If what you want to know is who was related to whom, and exactly how, Dynastiae was built for that from the ground up, not bolted on as an afterthought.

Relationship Search and Kinship Analysis

Dynastiae's signature feature is its relationship search: pick any two people in the database, and the app finds and displays the shortest path of kinship between them — exactly which people and unions that path passes through. The algorithm deliberately favors genuine blood kinship — a straight ancestor-descendant line — over a shorter-looking connection through marriage, since real blood kinship is usually what someone is actually looking for, even if it means a longer chain of generations. Only when no direct blood relation exists does the search fall back to the shortest connection available at all — through marriage, siblings, or cousins — and says so explicitly, instead of quietly passing off a different kind of connection as blood kinship.

Particularly interesting relationships — like exactly how Rurik, progenitor of the Rurikid dynasty, connects to King Philip II of France, despite centuries and thousands of kilometers between them — are additionally curated as standalone pages under Relations, with a full description of every link in the chain: who was whose father, mother, husband, or wife, and which dynasty they belonged to. Every curated relation can also be opened directly on the live graph, with the whole path highlighted.

Exploring Dynasties and Titles

Every dynasty in the database has its own overview page listing all of its members with links to their individual pages — and from there, one click opens any person directly on the interactive graph, ready to keep expanding their connections further. Side branches of the same dynasty (a specific cadet line within a larger house, say) are grouped together with the main line, so you see the whole house, not just a torn-off fragment of it.

Titles — royal, ducal, ecclesiastical — have their own pages collecting every historical holder of a given title in the order they succeeded one another, which is a separate, practical way of exploring the same network: not starting from a person, but from an office or dignity that different people, sometimes from entirely different dynasties, held one after another.

Who Dynastiae Is For

Dynastiae is useful to anyone trying to understand the structure of power and kinship in medieval and early modern Europe — out of pure curiosity, while writing a paper, preparing teaching material, or building a story grounded in real dynastic history. Instead of reading dozens of separate articles about individual rulers, you can trace their entire network of connections in one place — and see for yourself exactly how close, or how distant, they really were.
