The very name El Cid sums up much of the special character of medieval
Spanish warfare. It comes from the Arabic al sayyid, master or
chieftain, and seems to have been given to Rodrigo de Vivar by his
Muslim foes. But was it given in recognition of El Cid's victories
against Islam in the 'Reconquista' - or because this Castilian nobleman
was as content to serve beside the Muslims as to fight them? The story
of the Christian conquest of the Iberian peninsula which gave rise to
the legend of El Cid, is here examined by David Nicolle, who outlines
the history, tactics, arms and armour of the period.
