Estelada
The Estelada is an unofficial flag symbolizing support for Catalan independence, derived from the Senyera—the historic banner of the Crown of Aragon consisting of four red stripes on a yellow field—by adding a white five-pointed star enclosed in a triangular hoist-side panel.[1][2]Two main variants exist: the Estelada blava, featuring a blue triangle and associated with centrist or conservative-leaning independence advocates, and the Estelada roja, with a red triangle emblematic of left-wing, socialist, or republican factions within the movement.[3][4]
Designed by Vicenç Albert Ballester and first documented in use around 1918, the Estelada draws from the independence flags of Cuba and Puerto Rico, reflecting historical Catalan exile solidarity with anti-Spanish colonial efforts.[2][3][5]
Lacking official status, it has emerged as the preeminent emblem of separatist aspirations, prominently displayed during mass demonstrations and cultural events advocating for a sovereign Catalonia or broader Països Catalans.[1][5]
