Gurs internment camp was an internment camp and prisoner of war camp constructed in 1939 in Gurs, a site in southwestern France, not far from Pau. The camp was originally set up by the French government after the fall of Catalonia at the end of the Spanish Civil War to control those who fled Spain out of fear of retaliation from Francisco Franco's regime. At the start of World War II, the French government interned 4,000 German Jews as "enemy aliens", along with French socialist political leaders and those who opposed the war with Germany.

Karlsruhe is the third-largest city of the German state of Baden-Württemberg, after its capital Stuttgart and Mannheim, and the 22nd-largest city in the nation, with 308,436 inhabitants. It is also a former capital of Baden, a historic region named after Hohenbaden Castle in the city of Baden-Baden. Located on the right bank of the Rhine near the French border, between the Mannheim-Ludwigshafen conurbation to the north and Strasbourg to the south, Karlsruhe is Germany's legal center, being home to the Federal Constitutional Court, the Federal Court of Justice and the Public Prosecutor General.
