After the death of his father Ferdinand II in January 1188, young Alfonso IX ascends to the throne of the Kingdom of León amid political and economic fragility. He convenes an extraordinary Curia Regia in the cloister of the Basilica of San Isidoro de León. The clergy participates through the Archbishop of Santiago de Compostela and other bishops; the nobility through counts, magnates, and barons; and, for the first time in Europe's documented history, the kingdom's cities are represented through elected "good men" or citizens of each council — uniting the three estates of the realm in a single council. The resulting Decreta de León comprises seventeen statutes recognizing home and correspondence inviolability, the right to appeal justice against the king himself, and the monarch's obligation to consult the Cortes before declaring war or peace. In 2013, UNESCO inscribed the 1188 Decreta de León in the Memory of the World Register, recognizing them as "the oldest documentary testimony of the European parliamentary system".
