The success of Ferdinand’s campaign is made…

The success of Ferdinand’s campaign is made possible by the preoccupation of the Zaragozan emir, Ahmad al-Muqtadir, with attacking the neighboring taifa of Tortosa and defending his northeastern frontier from Ramiro I of Aragon and Raymond Berengar I of Barcelona.

The emir, up until then paying tribute to Sancho IV of Navarre, submits to Ferdinand and agrees to pay parias.

Although probably originally meant to be temporary, Ferdinand will manage to enforce the tribute until his death.
