The Kingdom of Luxembourg-Nassau is the largest of the three european constituent semi-autonomous kingdoms forming the United Netherlands. The capital is Luxembourg and the population around 11 million.
Its core is Luxembourg County, which rose suddenly from obscure fief on the margins of the Holy Roman Empire to European power after the election of Henry VII to Holy Roman Emperor in 1301. Most of the Luxembourgs' interests would lie in central europe and Italia however John III's wars would begin the slow accretion of territory in western europe.
Thereafter a succession of territories would be seized:
- Champagne in 1523 following the War of Anglian Succession
- Nassau in 1547 after the War of the Nassau Succession
- Rethel in 1604
- Sponheim in 1613 (Trier War)
- Bishoprics of Metz, Toul and Verdun (conquered and secularised during Fifty Years War)
- Cities of Metz and Weissenberg in 1668 (Imperial Cities de-established following the Fifty Years' War)
- Archbishopric of Trier (secularised 1574), inherited 1720
- Bar and Wittgenstein in 1731
- Lorraine in 1783 during the Six Year War (or War of Regensburg Succession)
- Bishopric of Spires in 1699 (later swapped with the Palatinate to guarantee the inheritance of Baden-Durlach in 1746).
Many of these territories would be devastated by war and frequently repopulated with Flemish or Dutch cementing Lutheranism and alliegance to the Luxembourg rulers.
Finally in 1906 the whole collection of counties would be united into a single kingdom under the Luxembourg-Nassau Reform Law, like Flanders and Holland-Utrecht were at the same time.
The same law enshrined the triplication of all signage etc into the three main languages; Luxembourgish (Letzeburgesch), French and German. Dutch is a widely spoken second language.
Luxembourg and the Saarland are dominated by heavy industry; coal mining and iron and steel. Bar-Lorraine (Loutrengen) is noted for textile manufacturing. Champagne is mostly agricultural although most famous for its sparkling wine. Wine is also grown throughout the entire kingdom. The kingdom is well-served by an extensive railway network and the recent canalisation of parts of the Musel River has improved the connections between the industrial regions.
