Catalan pro-independence supporters hold a giant "Estelada" (Catalan separatist flag) during a demonstration called "Via Lliure a la Republica Catalana" (Way of Freedom for the Republic of Catalonia) on Catalunya's National Day in Barcelona, Spain, on September 11. Thousands of people packed the streets to call for Catalonia to break away from Spain, two weeks before a September 27 regional election that many see as a "make-or-break" moment for the independence movement
