Who here has family who emigrated from the Grand Duchy?
The written history of "Luxembourg" starts in the year 963, when Sigefroid, Count of the Ardennes, and founder of the Luxembourg dynasty, had a castle built on the territory of the present-day Capital of Luxembourg. This castle was the origin of the establishment of a town, which for nine centuries was to develop into a formidable fortress, known as "Gibraltar of the North". The inhabitants of Luxembourg-city were granted civil liberties as early as 1244 by Countess Ermesinde. The 14th century saw four members of the first House of Luxembourg (Henri VII, Charles IV, Wenceslas and Sigismond) become Emperors of the Holy Roman Empire. Others became kings of Bohemia and of Hungary. Emperor Charles IV elevated the County of Luxembourg to the rank of Duchy in 1354.
After a long period of foreign sovereignty (Burgundian / Spanish / French / Austrian / Revolutionary French) Luxembourg regained its national independence in 1815. The Congress of Vienna settled the destiny of the country, by raising it to the rank of Grand Duchy, and by giving it as personal property to the King of the Netherlands (William I of Orange-Nassau).
This personal union between Luxembourg and the Netherlands lasted until 1890. During this period the political independence and autonomy were strenghtened, and the democratic institutions were developed. The 11th of May 1867 is one of the most important dates in national history. The Treaty of London reaffirmed Luxembourg's territorial integrity, and the political autonomy which had already been granted by the Treaty of London of 1839. Furthermore, Luxembourg was declared perpetually neutral, and the great powers agreed to guarantee and to protect the neutrality of the Grand Duchy.
