Pro-independence advocates claim that that this invasion has repressed the region ever since.The aim of the new campaign is to raise awareness to the historical reasons why Catalonia should be independent, rather than focusing on the financial crisis, which some critics claim is dragging Catalonia down along with Spain.Sapiens magazine editor, Claudia Puyol told Voz Populi (in Catalan): "It’s one of the most decisive moments in our history.”"The Catalan cause is one of the most unknown in the world," she added.The above video, which unfortunately does not have English sub-titles, shows people in many areas of the world being asked if they know about Catalonia, and the resulting replies show that most of them have never heard of the region.
