Sisebut (Latin: Sisebutus; Spanish: Sisebuto; also Sisebuth, Sisebur, Sisebod or Sigebut; c. 565 – February 621) was King of the Visigoths and ruler of Hispania, Gallaecia, and Septimania from 612 until his death in 621. His rule was marked by forced Christian conversion, anti-Judaic measures, Roman-like administration, and intellectual cosmopolitanism.
Isidore of Seville (Latin: Isidorus Hispalensis; c. 560 – 4 April 636) was a Hispano-Roman scholar, theologian and archbishop of Seville. He is widely regarded, in the words of the 19th-century historian Charles Forbes René de Montalembert, as "the last scholar of the ancient world".
At a time of disintegration of classical culture, aristocratic violence, and widespread illiteracy, Isidore was involved in the conversion of the Arian Visigothic kings to Catholicism, both assisting his brother Leander of Seville and continuing after Leander's death. He was influential in the inner circle of Sisebut, Visigothic king of Hispania. Like Leander, he played a prominent role in the Councils of Toledo and Seville.
