The term implied these were not constitutions subject to debate and change by a sovereign people, but orders from the only legitimate source of authority, as in feudal times.
In the letter Adams also commented on the substantial independence of the hereditary Basque Jauntxo families as the origin for their privileges.
In practice, distinct fueros for specific classes, estates, towns, or regions usually arose out of feudal power politics.
The classic example of such a privileged group was the Roman Catholic Church: the clergy did not pay taxes to the state, enjoyed the income via tithes of local landholding, and were not subject to the civil courts.
Another example was the powerful Mesta organization, composed of wealthy sheepherders, who were granted vast grazing rights in Andalusia after that land was reconquered by Spanish Christians from the Muslims (see Reconquista).
[2] During the Reconquista, the feudal lords granted fueros to some villas and cities, to encourage the colonization of the frontier and of commercial routes.
They enshrined the traditional principle "laws before kings" both in Aragonese and Navarrese law, justified the right to rebel against illegal royal decisions, and legitimised the existence of specific institutions such as the Justicia de Aragón, designed to The Fueros de Sobrarbe first appear mentioned in the context of the ascension of the House of Champagne to the Navarrese throne.
The loyalty of the Basques (the Navarri) to the king was conditioned on his upholding the traditions and customs of the kingdom, which were based on oral laws.
In order to gain Navarrese loyalty, the Spanish Crown represented by the Aragonese Fernando upheld the kingdom's specific laws (fueros) allowing the region to continue to function under its historic laws,[3]: 36–39, 44 while Lower Navarre remained independent, but increasingly tied to France, a process completed after King Henry III of Navarre and IV of France died.
[3]: 39–43 In addition, the ever more centralizing absolutism, especially after the accession to the throne of the Bourbons, increasingly devalued the laws specific to regions and realms—Basque provinces and the kingdoms of Navarre and Aragon—sparking uprisings (Matalaz's uprising in Soule 1660,[7]: 267 regular Matxinada revolts in the 17-18th centuries) and mounting tensions between the territorial governments and the Spanish central government of Charles III and Charles IV, to the point of considering the Parliament of Navarre dangerous to the royal authority and condemning "its spirit of independence and liberties.
[3]: 45 The Aragonese fueros were an obstacle for Philip II when his former secretary Antonio Pérez escaped the death penalty by fleeing to Aragon.
The Aragonese count of Robres, one strongly opposing the abolition, put it down to Castilian centralism, stating that the royal prime minister, the Count-Duke of Olivares, had at last a free rein "for the kings of Spain to be independent of all laws save those of their own conscience.
"[10] The Basques managed to retain their specific status for a few years after 1714, as they had supported the claimant who became Philip V of Spain, a king hailing from the lineage of Henry III of Navarre.
In the run-up to the Napoleonic Wars, the relations between the absolutist Spanish Crown and the Basque governing institutions were at breaking point.
By the beginning of the War of the Pyrenees, Manuel Godoy took office as Prime Minister in Spain, and went on to take a tough approach on the Basque self-government and specific laws.
The 1789 Revolution brought the rise of the Jacobin nation state—also referred to in a Spanish context as "unitarism",[citation needed] unrelated to the religious view of similar name.
In the French Basque Country, what little remained of self-government was suppressed in 1790 during the French Revolution and the new administrative arrangement,[7]: 267 and was followed by the interruption of the customary cross-border trade between the Basque districts (holding minor internal customs or duties), the mass deportation to the Landes of thousands of residents in the bordering villages of Labourd—Sara, Itxassou, Ascain—,[11]: 18 including the imposition (fleetingly) of alien names to villages and towns—period of the National Convention and War of the Pyrenees (1793–1795).
The Carlist land-based small nobility (jauntxos) lost power to the new bourgeoisie, who welcomed the extension of Spanish customs borders from the Ebro to the Pyrenees.
The new borders protected the fledgling Basque industry from foreign competition and opened the Spanish market, but lost opportunities abroad since customs were imposed on the Pyrenees and the coast.
Despite capitulation agreements acknowledging specific administrative and economic prerogatives, attempts of the Spanish government to bypass them spread malaise and anger in the Basque districts, ultimately leading to the 1893–94 Gamazada uprising in Navarre.
An attempt was made at restoring some kind of Basque self-government in the Statute of Estella, initially garnering a majority of the votes, but controversially failing to take off (Pamplona, 1932).
After the 1981 coup d'état attempt and the ensuing passing of the restrictive LOAPA act, such possibility of autonomy got opened to whatever (reshaped) Spanish region demanded it (such as Castile and León, Valencia, etc.
The State of Autonomous Communities took the shape of administrative districts and was ambiguous as to the actual recognition of separate identities, coming to be known as café para todos, or 'coffee for everyone'.
However, the provincial chartered governments (Diputación Foral / Foru Aldundia) in the Basque districts were restored, getting back significant powers.
The crown attempted to curtail the fuero eclesiástico, which gave the lower secular (diocesan) clergy privileges that separated them legally from their plebeian parishioners.
The curtailment of the fuero has been seen as a reason why so many clerics participated in the Mexican War of Independence, including insurgency leaders Miguel Hidalgo and José María Morelos.
Removal of the fuero was seen by the Church as another act of the Bourbon Reforms that alienated the Mexican population, including American-born Spaniards.
