 The Organic Law of the Financing of Autonomous Communities of 1988 requires that the communities obtain the authorization of the central Ministry of Finance to issue public debt.The preamble to the constitution explicitly stated that it is the nation's will to protect "all Spaniards and the peoples of Spain in the exercise of human rights, their cultures and traditions, languages and institutions".This is a significant recognition not only in that it differed drastically from the restrictive linguistic policies during the Franco era, but also because part of the distinctiveness of the "historical nationalities" lies on their own regional languages.
