On the basis of the new Spanish Constitution and with the approval of the Basque Autonomy Statute and the Navarre Autonomy Statute, the autonomy regime was established in the Basque Country, along with other nations and regions (seventeen in total) which also approved their autonomies. However, right-wing parties, the state apparatus, and centralist sections of left-wing Spanish parties considered the power attributed to these autonomies to be too high. The old regime forces promoted a coup d’état attempt in 1981, which, although not completely successful, created a setback for the decentralisation process, crystallised in the Organic Law for the Harmonisation of the Autonomy Process (LOAPA).
