The Fourth Council of Toledo was held in 633. It was convened by Visigothic king Sisenand and took place at the church of Saint Leocadia in Toledo.
Probably under the presidency of the noted Isidore of Seville, the council regulated many matters of discipline, decreed uniformity of liturgy throughout the Visigothic kingdom and took stringent measures against baptized Jews who had relapsed into their former faith.
The Third Council of Toledo (589) marks the entry of Visigothic Spain into the Catholic Church, and is known for codifying the filioque clause into Western Christianity. The council also enacted restrictions on Jews, and the conversion of the country to Catholic Christianity led to repeated conflict with the Jews.
The Twelfth Council of Toledo, held in Toledo, Spain, was initiated on 9 January 681 by the Visigothic King Erwig, who was elected king in 680. One of its first actions was to release the population from the laws of Wamba and recognise Erwig, anathematising all who opposed him.
The Council was attended by thirty eight bishops, four abbots, and five palatine officials. It recognised the right of the metropolitan archbishop of Toledo to consecrate all bishops appointed by the king, even if they were outside his own province. Thus was born the primacy of the Toledan diocese over all Spain.
