The Principality of Luxembourg (Letzeburgish: Fürstentum Lëtzebuerg) is a principality and constituent country of Großgermania. Its territory is the same as that of the Grand Duchy of Luxembourg. It is a National Unionist monarchy, and consists of a single province, which exists for administrative reasons only and has no political or economic government.
Luxembourg was part of Gaul (see: Celtic Luxembourg) until it was conquered by the Roman Empire and incorporated into the province of Belgica Prima. Falling under the control of the Carolingian Empire after the fall of Rome, a castle, Lucilinburhuc, was constructed by the Middle Frankish Kingdom to exact tribute from trade through the region between East and West Francia. This led to discontent on the behalf of those nations, however, which coupled with the dissatisfaction of inheritence on the part of Louis II, Holy Roman Emperor to lead to an invasion of Lotharingia (of which Luxembourg was a part) in 858.
In 963, Lucilinburhuc was acquired by Siegfried, Count of Ardennes, who founded the County of Luxembourg, which became the Duchy of Luxembourg in 1441. The House of Luxembourg ruled the county for most of its history, until it passed to the House of Nassau under the Congress of Vienna in 1815 (as the Grand Duchy of Luxembourg), in personal union with the United Kingdom of the Netherlands and the Kingdom of the Netherlands until 1890. Invaded by the German Empire in the First World War and annexed by the Großdeutsches Reich in the Second World War, Luxembourg abandoned neutrality to join the North Atlantic Treaty Organization after that war. A founding member of the European Union, Luxembourg left that organization in 2008 to join the Association of Germanic States when the EU attempted to incorporate Luxembourg into the French military base being established over much of Belgium. It subsequently merged into Großgermania, becoming reclassified as a principality.
