Alfonso VII of León and Castile (b. 1105)
Alfonso VII (1 March 1105 – 21 August 1157), called the Emperor (el Emperador), became the King of Galicia in 1111 and King of León and Castile in 1126. Alfonso, born Alfonso Raimúndez, first used the title Emperor of All Spain, alongside his mother Urraca, once she vested him with the direct rule of Toledo in 1116. Alfonso later held another investiture in 1135 in a grand ceremony reasserting his claims to the imperial title. He was the son of Urraca of León and Raymond of Burgundy, the first of the House of Ivrea to rule in the Iberian peninsula.

Alfonso was a dignified and somewhat enigmatic figure. 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. He was a patron of poets, including, probably, the troubadour Marcabru.
