I want to know the answer to the following question:
What law made Valencia the capital of its region?
All the background I'm provided with is that "On the night of 23 February 1981, shortly after Antonio Tejero had stormed Congress, the Captain General of the Third Military Region, Jaime Milans del Bosch, rose up in Valencia, put tanks on the streets, declared a state of emergency and tried to convince other senior military figures to support the coup.". Is that enough to answer the question?
Answer: no
