Overview

Duché de Luxembourg; from "Lucilinburhuc" ("little fortress"). Founded in 963 when Count Siegfried of the Ardennes acquired the promontory of Lucilinburhuc by exchange with the Abbey of St Maximin, Trier; his descendants took the comital title (c. 1059/1060). In the 14th century the counts rose to European eminence: Count Henry VII became Holy Roman Emperor (1312–1313); his descendant Charles IV (Emperor 1355–1378) elevated Luxembourg to a duchy on 13 March 1354 for Wenceslaus I, its first duke; Wenceslaus (King of the Romans 1376–1400) and Sigismund (Emperor 1433–1437, whose death ended the senior line) followed. The last Luxembourg-line ruler, Elisabeth of Görlitz, pledged the duchy to Philip the Good of Burgundy (effective 1443); with the Burgundian inheritance it passed to the Habsburgs (1477/1482) and became part of the Habsburg, Spanish and Austrian Netherlands.

This compendium cites its sources once for the whole document rather than per territory. Its bibliography names the English Wikipedia articles for each territory as the primary basis, cross-checked against Encyclopædia Britannica and specialist snippets, and flags entries built on unreliable foundations — the 911 treaty of Saint-Clair-sur-Epte known only from Dudo of Saint-Quentin, and Arnaud Amalric's alleged order at Béziers attested only decades after the fact.
