Beginning in 654 Recceswinth was responsible for the promulgation of a law code to replace the Breviary of Alaric; he placed a Visigothic common law over both Goths and Hispano-Romans in the kingdom. However, this Liber Judiciorum showed little Germanic influence, adhering more closely to the old Roman laws.citation needed
Moreover, the church councils in the capital became the most powerful force in the government and the bishops the primary support of the monarchy. Will Durant writes in The Age of Faith: "By their superior education and organization they dominated the nobles who sat with them in the ruling councils of Toledo; and though the king's authority was theoretically absolute, and he chose the bishops, these councils elected him, and exacted pledges of policy in advance."citation needed
