Meanwhile in Spain, after the death of the Gothic king Witiza in the year 90 (708-709), anarchy arose, which was terminated by the council of noblemen at Toledo electing Roderic, the powerful duke of Baetica, to be his successor in the fifth year of Walid.
The eldest son of Witiza then applied to Julian, and asked the aid of the Arabs for the recovery of his father's throne.
This expedition, seconded by partisans of Witiza, was successful.
Fearing lest he should have escaped to Toledo and should there fit out another army, the partisans of Witiza insisted that Tariq should march immediately against the capital.
Already, before the expedition to Salamanca, he had perceived that the sons of Witiza had neither military nor political ability.
The battle near Tamames and the part played by the sons of Witiza, are based, not on documentary evidence, but on probable inferences.
