Aguila Roja is a Spanish historical adventure television series set in 17th century Spain, first broadcast in 2009. Its hero, schoolteacher Gonzalo de Montalvo, leads a secret life as a masked swordsman fighting corruption while protecting his family. Swordplay is central to the show, with duels and ambushes in almost every episode. Clips labelled espada, the Spanish word for sword, circulate online among fans editing fight scenes and tributes, and the blade sounds have become a handy shortcut for period action and heroic confrontations.
