2016 Spanish regional elections

Determination of election day varied depending on the autonomous community. Typically, most autonomous communities held their elections on the fourth Sunday of May every four years, concurrently with nationwide local elections, while others had their own, separate electoral cycles. In some cases, regional presidents had the prerogative to dissolve parliament and call for extra elections at a different time, but newly elected assemblies were restricted to serving out what remained of their previous four year-terms without altering the period to their next ordinary election. In other cases—Andalusia (since 1994), Aragon (2007), the Balearic Islands (2007), the Basque Country (1981), Castile and León (2007), Catalonia (1985), Extremadura (2011), Galicia (1985), Navarre (2010) and the Valencian Community (2006)—the law granted regional presidents the power to call snap elections resulting in fresh four-year parliamentary terms.^[1][2]
