in 1252, Alfonso X " (The Wise One) battled the moors and obtained
the title of King of the Romans by the Archbishop of Treveris
on behalf of the Electors of Saxony, Brandensburg and Bohemia.
While away, the Cortes in Segovia named heir to the throne his
second son Don Sancho. This brought on a civil war while the moorish
troops were burning the Castillian fleet at Tarifa in 1278 and
Pamplona fell to the French. Alfonso warred against his son but
died grief stricken on 1284.
His true legacy was more intellectual, legal and literary than
military. His General Chronicle of Spain and his Great
and General History are considered exemplar. His Code of
Seven Acts is a monumental work of jurisprudence, influential
even today. He also wrote extensively on science, astronomy and
astrology and published his famous work of poems Cantigas de
Santa Maria in the galician language.
