Rodrigo's life changed many times due to the wars around him. He first served King Sancho II of Castile. In 1065, he became a high-ranking commander for the king. He led many battles to help expand the kingdom's lands. However, King Sancho was killed in 1072. His brother, Alfonso VI, became the new king of Castile and León. Alfonso did not trust Rodrigo very much. Because of this lack of trust, Rodrigo was sent into exile in 1081. 
During his time in exile, Rodrigo proved he was a great strategist. He found work defending the Muslim rulers of Zaragoza. He won many battles against different armies during these years. He even defeated a large Christian army led by King Sancho Ramírez of Aragon. Eventually, the new challenges in Spain forced King Alfonso to ask for Rodrigo's help again. Rodrigo returned to service for his former lord. He spent his later years fighting against the Almoravid Berbers.

In 1094, he established an independent rule over the Principality of Valencia. He ruled this area on the Mediterranean coast for a few years. He led a society where Christians and Muslims lived together. Rodrigo died on July 10, 1099. His wife, Jimena Díaz, took over as the ruler of Valencia after him.

Rodrigo Díaz de Vivar was a prominent Castilian knight and ruler in medieval Spain. 
Rodrigo was born around 1043 in Vivar, a village near Burgos. His father, Diego Laínez, was a cavalryman and a court official. Rodrigo grew up in the court of Ferdinand the Great. He eventually entered the service of Ferdinand's son, Sancho II of León and Castile. By 1065, Rodrigo had become the armiger regis, or royal standard-bearer, of Castile. This was a high-ranking position that showed the king's trust in his military abilities. He led campaigns to expand the territory of the Crown of Castile against various rivals.
In 1072, the political landscape changed when Sancho II was assassinated during a siege at Zamora. Because Sancho had no children, his brother Alfonso VI became the king of Castile and León. The transition was difficult for Rodrigo. Alfonso suspected that many nobles were involved in his brother's death. According to the epic poem *Cantar de mio Cid*, Rodrigo even helped force Alfonso to swear oaths at the Church of Santa Gadea. 
Exile allowed Rodrigo to demonstrate his skills as a strategist and military leader. He found employment defending the Muslim rulers of Zaragoza against the kingdom of Aragon. During this period, he won several victories against the rulers of Lérida and their Christian allies. He even defeated a large Christian army led by King Sancho Ramírez of Aragon. His reputation grew so strong that the Almoravids, a North African group, eventually forced King Alfonso to seek Rodrigo's help. By 1086, Rodrigo had returned to the service of his former lord to defend Castile.
Rodrigo eventually shifted his focus toward the city of Valencia. He operated with a high degree of independence from King Alfonso VI. He supported various Muslim dynasties, such as the Banu Hud, to counter the influence of the Almoravids. In 1092, the Islamic ruler Yahya al-Qadir became a tributary to Rodrigo. Following an uprising that killed al-Qadir, Rodrigo laid siege to the city. In 1094, he successfully captured Valencia. He established the Principality of Valencia, ruling an independent territory on the Mediterranean coast. 
As the ruler of Valencia, Rodrigo managed a pluralistic society. This means his territory included both Christians and Muslims living together. He spent his final years defending this land against the Almoravid Berbers. In 1094, he won a major victory against them on the plains of Caurte. However, his family also faced loss during these conflicts. His only son and heir, Diego Rodríguez, died in 1097 while fighting the Almoravids for Alfonso. Rodrigo died on July 10, 1099.
After his death, Rodrigo's wife, Jimena Díaz, inherited his rule. She maintained control of Valencia until 1102, when the Moors reconquered the city.
