When Pedro caused his unfortunate wife, Blanche, to die in prison, from the dagger, or by poison, his subjects were at length aroused to indignation. The insensate ruler was bringing the nation to the verge of ruin by his misdeeds. France resented the dastardly murder of Blanche of Bourbon, and the King vowed revenge on Pedro. Enrique, brother of Pedro, was fighting for the crown, and had been proclaimed Sovereign at Toledo; while the Sevillians, who had long endured their King's severities and condoned his cruelties, were up in arms and threatening the royal palace. Pedro fled from Seville, and came eventually into Aquitaine, to the court of the English Black Prince at Bordeaux. The chivalrous Black Prince espoused the cause of Pedro against Enrique, pitying the fugitive King who had been forced to leave his country. In return for his support, Pedro offered his English ally a large sum of gold, and the great ruby stolen from Abu Said in the Alcázar of Seville. The campaign was decided in favour of the King of Spain, but its hardships cost the Black Prince his life. Pedro was again acknowledged King. His downfall was, however, fast approaching. Enrique conquered his brother, soon after the departure of the English army, and came to see him at Montiel in La Mancha. It is said that Pedro was treacherously drawn into a trap. In any case, he fell by the dagger of his brother Enrique; and so ended violently the life of one who had lived in violence and bloodshed. As our story is more concerned with the city of Seville than with the fortunes of the rulers of Spain, we may resume the narration at the time of Isabella and Fernando. No incidents of signal importance occurred in Seville between the death of Pedro I. and the accession of the famous Catholic Queen. With the reign of Isabella, the city became the theatre of events that influenced the whole of the nation, and indeed the whole of Christendom. It was at this time that the arts and letters of Spain began to revive. In Seville the year 1477 is the date of the first setting up of a printing press, by one Theodoricus el Aleman (the German). Konrad Haebler, in his work on _The Early Printers of Spain and Portugal_, says that for fifteen years the only printers in the city were German immigrants. One of the early important books printed in Seville was Diego de Valera's _Cronica de España_. In 1490 a firm of printers, under the title of Four German Companions, opened business, and in three years published nine volumes, while two years later there was a rival press owned by another German.
