Rodrigo Díaz de Vivar (1043–1099) was a Castilian nobleman and military leader in medieval Spain. He was called El Cid (the Lord) by the Moors and El Campeador (the Champion) by Christians. He is the national hero of Spain. Born a member of the minor nobility, El Cid was brought up at the court of the Spanish Emperor Ferdinand the Great and served in the household of Prince Sancho. He rose to become commander and the royal standard-bearer of Castile upon Sancho's ascension in 1065.
The Third Spanish Army were declining in numbers and increasing the ratio of arquebusiers and musketeers to pikemen, retaining none of the still common weapons such as crossbows, round shield or bucklers.
