The Laws of Toro Historical milestone · Toro, Alfoz de Toro, Zamora Image of Toro, not of the place itself. The Laws of Toro are the result of the legislative activity of the Catholic Monarchs, settled after the death of Isabella the Catholic on the occasion of the meeting of the Cortes in the city of Toro. Promulgated on 7 March 1505 in the name of Queen Joanna I of Castile, they form a body of eighty-three laws that governed Castilian civil law —entailed estates, marriage and inheritance— over the following centuries. The initiative stemmed from the will of Isabella herself, who entrusted the task to a commission of jurists including the Bishop of Cordoba and the doctors Díaz de Montalvo, Lorenzo Galíndez de Carvajal and Juan López de Palacios Rubios. They were established to compensate and attract the loyalty of the nobility, so that the patrimony of noble families would pass intact to the firstborn. 7 de marzo de 1505 Photo: GFreihalter (CC BY-SA 3.0) What to see and do in Toro
