I want to know the answer to the following question:
How did they manage the tensions in the present of Spanish Transition to democracy?
All the background I'm provided with is that "Besides, unlike in the federal system, the main taxes are taken centrally from Madrid (except for the Basque Country and Navarre, which were recognized in the Spanish democratic constitution as charter territories drawing from historical reasons) and then distributed to the Autonomous Communities.". Is that enough to answer the question?
Answer: no
