 His rule was characterised by the renewed supremacy of the western kingdoms of Christian Iberia over the eastern (Navarre and Aragón) after the reign of Alfonso the Battler.Though he sought to make the imperial title meaningful in practice to both Christian and Muslim populations, his hegemonic intentions never saw fruition.During his tenure, Portugal became "de facto" independent, in 1128, and was recognized as "de jure" independent, in 1143.
