Catalan declaration of independence
The Catalan declaration of independence (; ) was a resolution that was passed by the Parliament of Catalonia on 27 October 2017, which declared the independence of Catalonia from Spain and the founding of an independent Catalan Republic. The Act was immediately suspended by the Parliament. The declaration did not receive recognition from the international community. The declaration and proceeding vote were declared illegal as it was done on a simple majority and not the two-thirds requirement of the Catalan constitution.
National Day for Yes
After the 1978 Spanish transition to democracy, Catalonia regained some autonomy. After 25 years of political stability some requests of more autonomy started to appear, resulting in a Catalan Statute of Autonomy in 2005 which became law in 2006. Spanish institutions asked to ban the new law, declaring it unconstitutional in 2010. This situation, in addition to the 2008 crisis, fuelled the first major autonomy demonstration in Barcelona on July 10, 2010 when a million people marched under the banner "We are a nation. We decide."
