Upon marrying Rodrigo Díaz, Jimena Díaz accompanied her husband although it has remained unclear if she lived with him in the Taifa of Zaragoza during his first exile (from 1080 to 1086) as leader of the Andalusian army in service of Ahmah al-Muqtadir, Yusuf al-Mu'taman ibn Hud, and Al-Mustain II.
[b] At the beginning of the second exile of the Cid, in 1089, Jimena was imprisoned with her children, Cristina, Diego and María by mandate of Alfonso VI of León and Castile.
Nothing else is known about Jimena until the end of 1094, when Rodrigo Díaz, on October 21, winning the battle of Cuarte, secured his control over Valencia (that he had conquered on June 17 of that year) and she was reunited with her husband until his death in 1099.
From this point she was Lady of Valencia until 1102 when Alfonso VI, her kinsman, decided to set fire to and abandon the city to the Almoravids in response to the impossibility of defending it.
[3] Of her three children, Diego was killed in battle fighting under Alfonso VI in 1097, Cristina married Ramiro Sánchez of Monzón and became mother of king García Ramírez of Navarre, while Maria was successively wife of a prince of Aragón and Ramon Berenguer III, Count of Barcelona.
