I just got of the phone with Josep Maria Sole Sabaté, my friend and a leading Catalan historian and public intellectual. He was nothing short of breathless as he described the helicopters flying overhead stated flatly that he was in the the midst of a coup being carried out by the Spanish State.

He wanted to get in touch with me and others "out there" because he was not sure how much longer free communication would be available to him and other out in the street protesting against he Spanish central government’s arrest of members of the Catalan Autonomous government.

As of this writing at least six agencies of the Catalan Government have been the object of forced police searches and thirteen, mostly mid-level members of the Catalan government have been arrested.

The homes of two the leading architects of the incipient Catalan state, Carles Viver Pi i Sunyer and ex Spanish judge Santi Vidal, have been searched by police. The headquarters of the far-left CUP, part of the pro-vote coalition in the Catalan Parliament, has been surrounded by police.

Of course, the heavy handed actions of the Spanish central government are only riling up even more anti-Madrid sentiment while chasing fence sitters into the pro independence camp.

The leader of the Catalan National Congress Jordi Sanchez and the head of Omnium, a major Catalan cultural organization, Jordi Cuixart, has called Catalans to come into the streets and they have responded with a massive presence.

The mayor of Barcelona Ada Colau, who has been highly ambivalent regarding the referendum that is scheduled too take place on October 1st, has now come out firmly for the referendum and against the crackdown taking place. Albano Dante Fachin, head of the Podemos branch in Catalonia, which has been similarly ambivalent, is now off the fence fully supporting the right to decree and denouncing the aggression of the Spanish State.

The Catalans are not backing down:

The Catalan President Puigdemont has called and extraordinary meeting of his government. The president of the Catalan Parliament, Carme Forcadell has gone there to join him. At this moment, Puigdemont is currently in the Generalitat Palace, home of the Government meeting with his ministers. Crowds are outside in the Saint James square in the very heart of the city of Barcelona where both the Gneralitat and City Hall are located. People are lying down in the Via Laietana, a short walk away, one of the city’s main thoroughfares, in order to impede the Civil Guard’s ability to march upon government buildings.

The Ex-president of Catalonia, Artur Mas has said flatly that the vote will go on. Joan Tarda, one of the representatives of the Catalan Left Republican Party in the Parliament in Madrid, has made a public appeal for calm.

and are getting support from elsewhere in Spain

The Catalanist have received messages and protest of support from the Basque Country, where people have also taken to the streets, and Madrid itself, where a pro-democracy demonstration is currently taking place.

The Barcelona Football Club has come out in favor of those seeking to vote on October 1st.

And lest we forget, the Catalan people are known for their unity of purpose. Heck, it's their national sport:
