Degredado is the traditional Portuguese term for an exiled convict, especially between the 15th and 18th centuries. The term degredado (etymologically, a 'decreed one', from Latin decretum) is a traditional Portuguese legal term used to refer to anyone who was subject to legal restrictions on their movement, speech or labor. Exile is only one of several forms of legal impairment. But with the development of the Portuguese penal transportation system, the term degredado became synonymous with convict exiles, and exile itself referred to as degredo.
