 Another group was the "Estanqueros" or "Monopolists" ("estanco" means monopoly), a very heterogeneous political group under the leadership of Diego Portales.The name came out of the fact that most of them were merchants, and their leader, Portales, was in charge of the tobacco monopoly.Their principal figures were Juan Francisco Meneses (ex-monarchist); Manuel José Gandarillas (Carrera supporter) and José Antonio Rodríguez Aldea (O'Higgins supporter).
