The Council of Toledo refers to a series of church councils held in Toledo, Spain, primarily during the 6th and 7th centuries. These councils were significant in shaping the religious and political landscape of the Iberian Peninsula, particularly in relation to the Visigothic Kingdom. They addressed various theological issues, church governance, and the relationship between the church and the state. One of the most notable councils was the Third Council of Toledo in 589, which marked the conversion of the Visigoths from Arianism to Catholicism. This shift helped unify the kingdom under a single faith and strengthened the influence of the church in political matters, laying the groundwork for future religious developments in Spain.
