Spain is a parliamentary constitutional monarchy and a member of the [[European Union (EU)]] and [[eurozone]]. Its economy, the fourth-largest in the EU, combines modern industry with a strong services sector, particularly tourism (one of the world's most visited countries). Key economic sectors include tourism, agriculture (largest olive oil producer), automotive manufacturing, renewable energy, banking, and textiles. The country has significant regional autonomy with 17 autonomous communities, each with varying degrees of self-governance. Despite strong economic recovery since the 2008 financial crisis and successful modernization of its economy, Spain faces ongoing challenges with relatively high unemployment (particularly youth unemployment), regional economic disparities, and the need to balance regional autonomy with national unity. The country benefits from strong trade relationships within the EU and serves as a bridge to Latin American markets.
