Castilian nationalism
Castilian nationalism or "Castilianism" (Spanish: castellanismo) is a fringe political movement that advocates for the national recognition of Castile, and in some cases, its independence from Spain. == History == The 19th century saw the development of what historian Celso Almuiña terms as a Castilian "regio-nationalism", fostered by a sense of grievance against Catalonia among the Conservative milieus (supportive of the protectionist interests of the flour-making Bourgeoisie) who pitted themselves against central power in the wake of the 1843 free trading policies brought forward by Espartero.
