[1] The General and Extraordinary Cortes that met in the port of Cádiz starting 24 September 1810 "claimed legitimacy as the sole representative of Spanish sovereignty", following the French invasion and occupation of Spain during the Napoleonic Wars and the abdication of the monarch Ferdinand VII and his father Charles IV.
In order to further shore up French dominance and implement structural changes, Napoleon brought together as many aristocrats as possible to Bayonne, where they ratified "the first written constitution of the Spanish-speaking world."
[6] From the first days of the Peninsular War, which erupted in Spain; in resistance to the French invasion and occupation of the peninsula, local ruling bodies or juntas appeared as the underground opposition to the French-imposed government.
Convinced that unity was needed to co-ordinate efforts against the French and to deal with British aid, several provincial juntas, in Murcia, Valencia, Seville and Castile and León, called for the formation of a central body.
[7] Serving as surrogate for the absent royal government, it called for representatives from local provinces and overseas territories to meet in an "Extraordinary and General Cortes of the Spanish Nation."
New Spain was allocated 7 suplentes: Guatemala, 2; Cuba, 2; the Philippines, 2; Santo Domingo and Puerto Rico, 1; Spanish South America got 15: Peru, 5; Santa Fé, 3; Buenos Aires, 3; Venezuela, 2; and Chile, 2.
The composition of the Cortes of Cádiz was diverse, with about one-third clerical, one-sixth nobles and the remainder from the "third estate", the middle class.
Britain ordinarily would have been for the opening up of trade in Spanish America, but during the Peninsular conflict, it wanted as many troops as possible in Spain to defeat the French.
[14] Gaspar Melchor de Jovellanos, who had served as Charles IV's minister of justice but had been sidelined by Manuel Godoy, argued for the convocation of a general Cortes.
The aim of the publication was to "assist the Cortes frame a moderate constitution, and, more important, to effect reconciliation between the insurgent juntas in America and Spain."
He was deeply sympathetic to the Americans, publishing letters from Mexican elite Fray Servando Teresa de Mier and Buenos Aires creole patriot, Mariano Moreno, who had called for the opening of trade that would destroy the Spanish monopoly.
Conservative Spaniards saw the Cortes at Cádiz as, at best, an interim solution until "the Desired One", as Fernando VII was called by his supporters, could be restored to the throne.
They wanted equality before the law, a centralized government, an efficient civil service, a reform of the tax system, the replacement of feudal privileges by freedom of contract and the recognition of property rights.
The principal aim of the new constitution was the prevention of arbitrary and corrupt royal rule; it provided for a limited monarchy that governed through ministers subject to parliamentary control.
The constitution maintained that suffrage was not to be determined by property qualifications, and it favoured the position of the commercial class in the new parliament since there was no special provision for the Catholic Church or the nobility.
[17] The constitution set up a rational and efficient centralised administrative system, based on newly formed provinces and municipalities, rather than following historic boundaries.
[4] Its first regulation includes one of the first examples of a seasonally adjusted schedule, a practice which led to the adoption of daylight savings time a century later.
The majority of the Criollo people of Spanish America rejected the pretensions of the Spaniards and assumed the sovereignty of the former American kingdoms of the Crown of Castile, over which the King of Spain had been sovereign.
The fact that the Constitution was considered too liberal by the conservative elements in the colonies only precipitated their decision to join the effort for independence from Spain.
