Does Catalonia Have a Right to Secede? Lets discuss how this essay relates to the secession of 1860-65 concentrating on the Antebellum/Civil War era without referencing modern times. This sounds familiar. Loyalty, emotion and flag waving seems to be in the secession debates. That is not an easy question to answer because it is far from clear what would give any region a right to secede. The public debate – in Catalonia, Spain and elsewhere – is not much help. People tend to decide these issues on grounds of loyalty and emotion. There is a lot flag waving; much less reasoned argument.
