("Call for Solidarity in Defence of the Catalan Language, Culture and Nation"), which called for a mass meeting at the University of Barcelona, out of which a popular movement arose. The Crida organised a series of protests that culminated in a massive demonstration in the Camp Nou on 24 June 1981. Beginning as a cultural organisation, the Crida soon began to demand independence. In 1982, at a time of political uncertainty in Spain, the (LOAPA) was introduced in the Spanish parliament, supposedly to "harmonise" the autonomy process, but in reality to curb the power of Catalonia and the Basque region. There was a surge of popular protest against it. The Crida and others organised a huge rally against LOAPA in Barcelona on 14 March 1982. In March 1983, it was held to be ultra vires by the Spanish Constitutional Court. During the 1980s, the Crida was involved in nonviolent direct action, among other things campaigning for labelling in Catalan only, and targeting big companies. In 1983, the Crida's leader, Àngel Colom, left to join the ERC, "giving an impulse to the independentist refounding" of that party. Second Statute of Autonomy and after Following elections in 2003, the moderate nationalist Convergència i Unió (CiU), which had governed Catalonia since 1980, lost power to a coalition of left-wing parties composed of the Socialists' Party of Catalonia (PSC), the pro-independence Esquerra Republicana de Catalunya (ERC) and a far-left/Green coalition (ICV-EUiA), headed by Pasqual Maragall. The government produced a draft for a new Statute of Autonomy, which was supported by the CiU and was approved by the parliament by a large majority. The draft statute then had to be approved by the Spanish parliament, which could make changes; it did so, removing clauses on finance and the language, and an article stating that Catalonia was a nation. When the amended statute was put to a referendum on 18 June 2006, the ERC, in protest, called for a "no" vote. The statute was approved, but turnout was only 48.9%. At the subsequent election, the left-wing coalition was returned to power, this time under the leadership of José Montilla. In November 2005, Omnium Cultural organized a meeting of Catalan and Madrid intellectuals in the Círculo de bellas artes in Madrid to show support for ongoing reform of Catalan Statute of Autonomy, which sought to resolve territorial tensions, and among other things better protect the Catalan language.
