County of Luxembourg

963 CE – 1795 CE · capital Luxembourg

The castle-county on the Alzette that gave the Holy Roman Empire three emperors and grew into the duchy behind today's Grand Duchy.

Origins

In 963 Count Siegfried acquired the rock of Lucilinburhuc from the abbey of St Maximin at Trier and built a castle there. His descendants, and from 1136 the counts of Namur and later Limburg lines, expanded the county through the Ardennes and Moselle valley.

Rule and society

Luxembourg was a bilingual land of German and French speakers. Count Henry VII became emperor in 1308, and his son John the Blind, king of Bohemia, died at Crécy in 1346. Emperor Charles IV raised the county to a duchy in 1354. The fortress city became one of Europe's strongest, later rebuilt by Vauban.

Decline and legacy

Elisabeth of Görlitz ceded the duchy to Philip the Good of the Burgundian State in 1443. It then passed with the Habsburg Netherlands to the Spanish Netherlands and Austrian Netherlands, was briefly French in 1684–1697, and was annexed by France in 1795. It was revived as the Grand Duchy of Luxembourg in 1815.
