Later, Chamberlain argued that the Romans had become too tolerant of Semites like the Jews, and this was the cause of the downfall of the Roman empire. Chamberlain argued that it was due to miscegenation that the Jews had caused the Aryan Roman Empire to go into decline and collapse. Chamberlain wrote that the "African half breed soldier emperor" Caracalla had granted Roman citizenship to all the subjects in the Empire regardless of race or religion in 212 AD, and as result of this, the Romans had freely mixed with Semitic and African peoples, leading Chamberlain to conclude: "Like a cataract the alien blood poured down into the depopulated city of Rome and soon the Romans ceased to exist." As such, the destruction of the Western Roman Empire by the Germanic peoples was merely an act of liberation from the "Völkerchaos" ("Chaos of the Peoples") that the Roman empire had become.
