Águila negra : La apasionante historia de Sancho VII, el Fuerte, rey de Navarra

Navarre, 1194. Sancho VII—known as "the Strong" for his immense stature—ascends the throne, eager to follow in his father's footsteps and defend his land against the threat posed by the neighboring kingdoms of Castile and Aragon. However, as enemy attacks intensify, Sancho is forced down a difficult path: forging a pact with those who oppose his faith. Amidst the fierce siege of Vitoria—encircled by the troops of Alfonso VIII of Castile—the monarch makes a decision intended to alter his people's destiny. This desperate choice will haunt the new king for the rest of his days, plunging him into a spiral of bitterness and suspicion from which he will only emerge by taking part in the most epic battle of his era: Las Navas de Tolosa.
