Consejo Real de Castilla

"El Consejo Supremo de la Corona de Castilla o Real y Supremo Consejo de Castilla o Consejo Supremo de Castilla o Sacro Supremo Consilio Castiliae Coronae o Consejo de Castilla era la columna vertebral y principal centro de poder de la estructura de gobierno de la Monarquía Hispánica durante la Edad Moderna (siglos XVI a XIX), que se define como polisinodial, es decir, con multiplicidad de Consejos"

"The Council of Castile (Spanish: Real y Supremo Consejo de Castilla), known earlier as the Royal Council (Spanish: Consejo Real), was a ruling body and key part of the domestic government of the Crown of Castile, second only to the monarch himself. It was established under Queen Isabella I in 1480 as the chief body dealing with administrative and judicial matters of the realm. With the 1516 ascension of King Charles I (later Holy Roman Emperor Charles V) to the throne of both Castile and Aragon, the Royal Council came to be known as the Council of Castile because Charles was king of many dominions other than Castile, while the Council retained responsibility only over Castile. During periods in which there was no monarch, an absent monarch, or an incompetent monarch, the Royal Council would rule as a regency council in his place. The Council weakened in the 19th century, where it was abolished and re-established several times before being dissolved permanently."
