Do they have an armed seperatist wing The CRA, perhaps? They seem to have a police and fire service loyal to the cause.

The last time they had a civil war in Spain it spawned some decent books, anyway.

A few blokes with guns and explosives, financed by a wealthy backer or two can maintain a terrorist-style low-level insurgency but a full-on proper civil war with fronts and held territory and everything surely needs either a raid on a state armoury (Libya, for example, was plundered to provide the arms for Syrian rebels) and/or backing from a foreign power. Unless Catalonia has arms manufacturers.

Where did they get their weapons from last time?

The Krauts supplied one side and the Russians the other.

One can imagine a similar arrangement today...
