The Visigoths conquered the other Germanic tribes that had settled in Hispania in the 5th century. In the 6th century, the Visigoths established their kingdom's capital in Toledo to unite the Iberian Peninsula under their control. They adopted some Roman ways of life but also maintained their own customs. In 589, Visigoth King Recaredo I converted the kingdom to Catholicism, increasing the power of Catholic bishops, though Visigoths had previously followed Arianism.
