Its name has its origin in the number of its members, who were a hundred (cent in Catalan).
James I created the year 1249 the fundamental structure of the municipal government of Barcelona: a board of advice of 4 members, helped by 8 counselors and an assembly of probi homines -leaders- all them members of the mà major (Catalan for senior hand).
After several modifications, in the year 1265 the municipal organization remained definitively structured: the municipal authority fell on 3 counselors elected by a Council of a hundred personalities.
Another example is the negative of the Consell de Cent to accept the concession made by the king of a general study, Martin the Humane, the 10 January 1401, conceded the royal privilege of the foundation of the General Study of Medicine in Barcelona, with the same prerogatives that the one of Montpeller. This finally lead to the creation of University of Barcelona, in the year 1450.
