The Spanish Constitution was approved in 1978 following a referendum, marking a pivotal moment in the country's transition to democracy after decades of dictatorship. This new constitution established fundamental rights and freedoms, as well as autonomy for Spain's various regions. The ratification of the constitution not only symbolized a commitment to democratic governance but also laid the groundwork for Spain's modern political landscape.

The approval of the Spanish Constitution in 1978 enabled free expression, significantly boosting diverse regional literatures and poetry in multiple languages. Poets began to explore themes of identity, autonomy, and cultural diversity in their works, reflecting the newly found freedoms.
