Because Spain is currently one of the more decentralized country in the world?

Spain created the "autonomias" in order to appease secessionists.

Not a brilliant idea given them the control of the Education(that teaches them that Spain robs them and creates fiction about their past, all while rejecting Spanish), of the Police(so their friends could close roads without consequences), put levies to shops that used Spanish in their signs and tracks and harass those kids that use Spanish in School's recess.

BTW, the secessionist want to own Catalonia, but it feels too less to them, they also want Valencia and the Balearic Islands. And if you let them a big part of Aragón.
