The Consell de Cent (in Catalan; Valencian pronounced as /kunˈsɛʎ də ˈsen/, meaning in English "Council of One Hundred") was a governmental institution of Barcelona. It was established in the 13th century and lasted until the 18th century.Its name derives from the number of its members: one hundred .
In 1249, James I created the fundamental structure of the municipal government of Barcelona: a board of advice of four members, helped by eight counselors and an assembly of probi homines (leaders), all them members of the mà major (Catalan for senior hand, or the upper class formed by wealthy merchants).
After several modifications, by the year 1265, the municipal organization gained its more permanent structure: the municipal authority rested on three counselors elected by a Council of one hundred individuals.
In year 1335, Peter III the Ceremonious permitted the Consell de Cent to use the royal insignia of the four (red) bars.
The importance of the Consell de Cent in the history and the government of the Principality of Catalonia is supported by many examples. For instance, in year 1464 it proclaimed Peter V of Aragon (known as Peter the Constable of Portugal) as count of Barcelona. Another example is the rejection by the Consell de Cent of Martin the Humane's foundation on January 10, 1401, of the General Medical School in Barcelona with the same prerogatives as the University of Montpellier, because they felt this encroached on their municipal jurisdiction. This ultimately led to the creation of the University of Barcelona in 1450.
In the last decades of the 17th century it was represented in the (in Catalan: Conference of the Three Commons). The Consell de Cent was abolished by Philip V of Spain with the Decretos de Nueva Planta upon his occupation of Barcelona after the Siege of Barcelona in 1714. Since that moment, the new government of the city was controlled directly by the monarchy.
A main street in the city of Barcelona, the Carrer (street) del Consell de Cent, is named after this institution (before 1978 it was known as Calle del Consejo de Ciento, in Spanish).
