Ordenanças
The Ordenanças (meaning literally "Ordinances" in Portuguese and sometimes misspelled Ordenanzas in English language literature) were a militia-type traditional military territorial organization that existed in Portugal and in some parts of the Portuguese Empire (especially in Brazil), between the 15th and the 19th centuries.
In the 17th century, the Ordenanças became organized as a kind of third line and territorial recruitment reserve of the Portuguese Army.
