Open Image ModalA young girl is wrapped in a Catalan independence flag during a demonstration in support of a Catalan vote on independence from Spain, in the northern Spanish Basque city of Bilbao on September 9, 2014, ahead of the Diada. The Diada marks what many in this northeastern region see as the day they lost their autonomy: September 11, 1714, when Barcelona fell to Spanish and French forces in the War of Succession that redrew the map of Spain. This year the Diada opens the final straight in the dash to hold a vote on whether Catalonia should break away from Spain -- a move the Spanish government has branded unconstitutional.
