Countess Ermesinde

House of Luxembourg

Luxembourg, once part of Charlemagne's empire, became an independent state in 963, when Siegfried, count of Ardennes, became sovereign of Lucilinburhuc (Little Fortress), a castle built on the territory of the present-day capital of Luxembourg. In 1060, Conrad, a descendant of Siegfried, took the title count of Luxembourg.

Numerous counts of the Ardennes succeeded Siegfried until Countess Ermesinde, the daughter of Henry IV of Namur, came to power in 1196. Historical accounts indicate that Ermesinde was a powerful, insightful and beloved ruler, who led Luxembourg into the intellectual, artistic, and religious renaissance that characterized western Europe. During her reign, which ended with her death in 1247, Luxembourg's area had grown fourfold, solvency had been attained, loyalties had been cemented, peace had been fostered, and cultural idiosyncracy had continued to define itself. ..... more
