2008, the First Major Pro-Independence Demonstration
Som una nació, volem un estat propi
Although I would agree 2012 saw the first massive pro-independence –i.e. over one-million–, I consider the first major one –in the tens of thousands– was in 2008, headed by the slogan "We are a nation–we want our own state" (i.e. not Spain). The main reason for the relatively small numbers was that it was called by a grass-roots organisation, Sobirania i Progrés, and the only parliamentary party to back it was Esquerra Republicana. It was, however, the chief signal showing that Catalan society was clearly heading towards today's pro-independence majority.
