(by virtue of
lineage) are "those for whom there is no memory of its origin and there is no knowledge of any document mentioning a royal grant, which obscurity is universally praised even more than those noblemen who know otherwise their origin", or in other words, an
immemorial noble. When challenged, a may obtain a judicial sentence validating his nobility from the
Royal Chancillería of Valladolid or Granada, if he can prove that it has been accepted by local society and custom. In this case, the resulting legal document that verifies his nobility is called a (
letters patent of nobility). ("four-sided noble"), one had to prove that all four of one's grandparents were . were regarded as the most noble and treated with the most respect. To qualify as a ("ancestral hidalgo") ("
fly-of-the-trousers hidalgo") obtained tax exemption for having seven sons in lawful wedlock. In
Asturias,
Cantabria and other regions of Spain every seven years the King ordered the creation of ("registers") where the population was classified either as , and therefore, exempt from taxation due to their military status or (from an
archaic verb, , "to pay") who comprised the ("lower ranks") and were excluded from military service and had to pay taxes. These constitute nowadays a source of information about population genealogy and distribution as well as proof of nobility in certain cases. On July 13, 1573,
Philip II of Spain issued the
Ordinances for the Discovery, the Population and the Pacification of the Indies which outlined the process to settle
New Spain and granted status to settlers who fulfilled their contracts and their legitament descendants.
Charles II of Spain issued a similar decree on March 22, 1697 that, among other matters, extended to the indigenous nobles of the Philippines, the , as well as to their descendants, the preeminence and honors customarily attributed to the hidalgos of Castile. Over the years the title lost its significance, especially in Spain where some regions practiced "universal hidalguía," granting noble status to anyone born in certain territories. Additionally, Kings routinely awarded the title in exchange for personal favors. By the time of the reign of the
House of Bourbon, over half a million people enjoyed tax exemptions, putting tremendous strain on the royal state which wasn't calling their services to arms but relied more on professional armies and costly mercenaries. Attempts were made to reform the title and by the early nineteenth century with the forced levies to military service of all citizens by
conscription without any minimum requirements of nobility or pay or loyalty by honour but by
coercion on
desertion, it had entirely disappeared, along with the social class it had originally signified and most of its centuries-old developed
code of honour in the nation's social culture. Influenced by policies in France, all became (taxpayers), without the privileges of the former title, and along with all citizens were also subject to conscription. Both
estates of the realm (social classes) became combined, compulsorily contributing to the nation in service and taxes without exemption, while the
titled nobility and royalty kept their former privileges and exemptions. ==Literature==
