and the French Cathedral, Berlin). The Huguenots furnished two new regiments of his army: the Altpreußische Infantry Regiments No. 13 (Regiment on foot Varenne) and 15 (Regiment on foot Wylich). Another 4,000 Huguenots settled in the German territories of Baden, Franconia (Principality of Bayreuth, Principality of Ansbach), Landgraviate of Hesse-Kassel, Duchy of Württemberg, in the Wetterau Association of Imperial Counts, in the Palatinate and Palatine Zweibrücken, in the Rhine-Main-Area (Frankfurt), in modern-day Saarland; and 1,500 found refuge in Hamburg, Bremen and Lower Saxony. Three hundred refugees were granted asylum at the court of George William, Duke of Brunswick-Lüneburg in Celle. In Berlin the Huguenots created two new neighbourhoods: Dorotheenstadt and Friedrichstadt. By 1700 one fifth of the city's population was French-speaking. The Berlin Huguenots preserved the French language in their church services for nearly a century. They ultimately decided to switch to German in protest against the occupation of Prussia by Napoleon in 1806–07. Many of their descendants rose to positions of prominence. Several congregations were founded throughout Germany and Scandinavia, such as those of Fredericia (Denmark), Berlin, Stockholm, Hamburg, Frankfurt, Helsinki, and Emden.

The Count supported mercantilism and welcomed technically skilled immigrants into his lands, regardless of their religion. The Condés established a thriving glass-making works, which provided wealth to the principality for many years. Other founding families created enterprises based on textiles and such traditional Huguenot occupations in France. The community and its congregation remain active to this day, with descendants of many of the founding families still living in the region. Some members of this community emigrated to the United States in the 1890s. In Bad Karlshafen, Hessen, Germany is the Huguenot Museum and Huguenot archive. The collection includes family histories, a library, and a picture archive. Effects The exodus of Huguenots from France created a brain drain, as many of them had occupied important places in society. The kingdom did not fully recover for years. The French crown's refusal to allow non-Catholics to settle in New France may help to explain that colony's low population compared to that of the neighbouring British colonies, which opened settlement to religious dissenters. By the start of the French and Indian War, the North American front of the Seven Years' War, a sizeable
