When did the Spanish language originate?
When Spain was liberated from the Moors, the two kingdoms that headed the “Reconquista” (Re-conquering) of Spain were Castilla, the strongest kingdom, and Aragon. The language of Castilla was the Castilian, now called Spanish, because all Spain was under the rule of Castilla after they conquered the New World and became the mightiest empire in the world at that time. After that, all Spain, beside the different languages spoken in other provinces, (Catalonia, Leon, Galicia, etc) , started to speak in Castilian or Spagnoli as it is also known, and spread in the conquered territories.
