Royal family trees, explained

Who was related to whom, who ruled next, and why. Every succession here is explained in plain words and cites its sources — and where nobody has reviewed it yet, the page says so instead of guessing.

Where the facts come from

Structure from Wikidata

Parents, marriages, children and reigns come from Wikidata (CC0) — 393 people in this collection, 207 of them with full records. Dates keep their precision: a record that only knows a century is not shown as a year.

Explanations reviewed by HistorIQly

Why a crown changed hands is a claim, not a data point. Each of the 22 transitions here was written and reviewed, with sources. Family links that sources dispute are labelled, not smoothed over.
