The Spanish autonomous community of Catalonia has a long established independence movement, which seeks to establish Catalonia as an independent and sovereign republic, thus breaking off from the Kingdom of Spain. A non-binding 2014 Catalan self-determination referendum resulted in a victory for proponents of Catalan independence (although with a turnout of 37%), which emboldened Catalan authorities to conduct the 2017 Catalan independence referendum, which they deemed would be binding and result in the independence of Catalonia.
