Later, Gobineau wrote a book Ce qui est arrivé à la France en 1870 ("What Happened to France in 1870") explaining the French defeat was due to racial degeneration, which no publisher chose to publish.[128] He argued the French bourgeoisie were "descended from Gallo-Roman slaves", which explained why they were no match for an army commanded by Junkers.[129] Gobineau attacked Napoleon III for his plans to rebuild Paris writing: "This city, pompously described as the capital of the universe, is in reality only the vast caravanserai for the idleness, greed and carousing of all Europe."[129]
