The first Spanish Constitution was a milestone in Spain’s political and social history. Born in a context of war and resistance, it represented an attempt to transform a country still anchored in absolutist structures towards a new model of national sovereignty, citizens’ rights and the separation of powers. It became popularly known as “La Pepa”, because it was promulgated on 19 March 1812, Saint Joseph’s Day, and it marked the beginning of modern Spanish constitutionalism.
At the beginning of the 19th century, Spain was living through a turbulent moment. The Napoleonic invasion had brought down the authority of Charles IV and his son Ferdinand VII, while the local Juntas and the Supreme Central Junta tried to maintain independence against French domination. In this climate of a power vacuum, the Cortes of Cádiz were convened, which would eventually give birth to a text intended to refound the country.
“The Spanish nation is free and independent, and it is not, nor can it be, the patrimony of any family or person”
Article 1 of the Constitution of 1812
That statement contained the seed of a political revolution. For the first time, sovereignty resided in the nation and not in the monarch. It was a paradigm shift that reflected the liberal spirit of the age and the influences of the Enlightenment and the French Revolution.
Context and causes of the Constitution of 1812
To understand the first Spanish Constitution, it is necessary to go back a few years. During the reign of Charles IV (1788–1808), the country was in crisis: the economy was faltering, internal tensions were growing, and the echo of the European revolutions stirred fears in the monarchy. The Mutiny of Aranjuez (1808) precipitated the abdication of Charles IV in favour of his son Ferdinand VII, who shortly afterwards would be taken to Bayonne by Napoleon and forced to renounce the throne.
Taking advantage of the power vacuum, the French imposed Joseph Bonaparte as king. However, popular resistance was not long in coming. Provincial Juntas emerged, organising themselves to fight the invasion and coordinate the defence of the country. These juntas delegated their authority to the Supreme Central Junta, which in 1810 convened Cortes in the city of Cádiz, the only bastion free from Napoleonic control.
There, amid cannons and siege, a group of liberal deputies, enlightened clergymen and representatives from America debated Spain’s political future. The result would be a constitution advanced for its time, inspired by the principles of liberty, equality and national sovereignty.
The deputy from Cádiz Agustín Argüelles stated in his famous speech:
“We find ourselves in the glorious case of constituting for the first time the Spanish Nation, of giving it a just government and wise laws”
Fundamental principles of the Constitution of 1812
The Constitution of Cádiz contained 384 articles distributed across 10 titles. Among its fundamental principles, the following stood out:
Principle
Description
Relevant articles
National sovereignty
Authority emanates from the nation, not from the king.
Article 1
Separation of powers
Three powers are established: legislative, executive and judicial.
Art. 15–17
Indirect suffrage
Male citizens over the age of 25 could vote in tiered elections.
Art. 91–92
Recognition of rights
Civil liberty, individual security, property and public education.

Art. 12
Abolition of privileges

Art. 248–259
Despite its liberal character, the Constitution of 1812 tried to reconcile Enlightenment ideas with Spain’s Catholic and monarchical tradition. Its balance between modernity and faith was, precisely, one of the reasons for its complex later application.
Chronology of the Spanish Constitution of 1812
The chronology of the Spanish Constitution, from its gestation in the Cortes of Cádiz to its definitive replacement by later texts, shows a process full of ups and downs, restorations and ruptures. It was a pioneering work, but also a victim of its time.

La Pepa: symbol of freedom
Popularly known as “La Pepa”, the first Spanish Constitution became a symbol of freedom and hope. Its promulgation in Cádiz was celebrated with enthusiasm, and the population shouted “¡Viva La Pepa!”, an expression that would eventually pass into popular language as a synonym of jubilation and release.
Although its application was brief, its legacy was lasting. It became a reference point for European and American liberal movements. In the new Spanish American republics, many constitution-makers drew direct inspiration from its text.
“The Constitution of 1812 was our birth certificate as a free nation; its spirit crossed the seas and lit bonfires of freedom in America”.
Antonio Alcalá Galiano – Liberal politician
In the words of the historian Javier de Burgos, one of the promoters of the later provincial division, “that Constitution was the first spark of modernity that illuminated a country still dominated by the shadows of the Ancien Régime”.
The protagonists of Cádiz
The Cortes of Cádiz brought together 303 deputies from very diverse backgrounds, including enlightened clergymen, jurists, military officers, merchants and representatives from America. Despite ideological differences, they shared a common objective: preserving Spain’s independence and laying the foundations of a legitimate government.
Among the most notable names were:

The application and fall of the Constitution
After its promulgation, La Pepa was sworn throughout Spanish territory and in the American colonies. However, its implementation faced enormous obstacles:
The War of Independence made any institutional stability difficult.
Many sectors of the clergy and nobility considered the Constitution a threat to the traditional order.
The return of Ferdinand VII in 1814 was a fatal blow, as the monarch abolished the text and restored absolutism.
During the Liberal Triennium (1820–1823), the first Spanish Constitution came back into force thanks to the pronunciamiento of General Rafael del Riego, who proclaimed the constitutional restoration in Las Cabezas de San Juan. That brief period was a heroic attempt to return power to the people, but it ended with the French invasion that reinstated the absolute king.
Legacy and later influence
The legacy of the first Spanish Constitution far transcended the brief time it was in force. Despite being repealed on several occasions, its liberal spirit left an indelible mark on the political history of Spain and much of Ibero-America. Many later constitutional texts, such as those of 1837, 1869, 1931 and the current one of 1978, draw directly from the principles established in Cádiz: national sovereignty, separation of powers and the affirmation of individual rights.
Its influence extended beyond Spain’s borders. In the new Latin American states that emerged after independence, the ideas of La Pepa served as a model of political organisation. The notion that power should emanate from the people and not from monarchs inspired constitution-makers in countries such as Mexico, Colombia or Argentina, who adapted their own texts based on that first Spanish attempt at modern constitutionalism.
In Europe, the Constitution of 1812 was closely observed by liberal currents fighting against the old absolutist regimes. Although later repression tried to erase its influence, the echo of Cádiz became a symbol of resistance against tyranny. Its memory resurfaced every time Spain tried to reinvent itself as a free nation, from the progressive movements of the 19th century to the democratic transition of the 20th century.
As the historian Manuel Moreno Alonso noted, “the Constitution of 1812 was not only a law, it was a declaration of principles, the political awakening of a nation learning to be free”. And that is perhaps its greatest heritage. It was not perfect nor fully applicable in its time, but it laid the foundations of modern political thought in Spain. In a country still seeking its identity after centuries of absolutism, La Pepa became the moral beacon that guided future generations towards an ideal of liberty, justice and citizenship.
The birth of Spanish constitutionalism
The first Spanish Constitution was much more than a legal document: it represented Spain’s entry into political modernity. Although its effective validity was limited, its ideas about sovereignty, liberty and equality before the law remain pillars of today’s democratic system.
Its drafting in the midst of war, in a besieged city, demonstrates the strength of a people who did not resign themselves to being vassals, but citizens. That is why, more than two centuries later, La Pepa continues to be remembered as the seed of Spanish freedom.
The current Constitution of 1978, heir to the spirit of Cádiz
More than a century and a half after the Constitution of 1812, Spain consolidated its democratic system with the approval of the Constitution of 1978, still in force today. After Franco’s dictatorship, the Law for Political Reform made it possible to hold free elections in 1977 and draft a new constitutional text, approved by the Cortes on 31 October 1978, ratified by citizens on 6 December and promulgated by King Juan Carlos I.

The new Magna Carta modernised the State, established universal suffrage, the separation of powers, the State of Autonomies and the Constitutional Court. Article 1 proclaims that “Spain is constituted as a social and democratic State governed by the rule of law… national sovereignty resides in the Spanish people”. This statement links directly with the spirit of La Pepa of 1812, where for the first time it was recognised that sovereignty emanated from the nation.
Thus, the liberal ideal born in Cádiz reached its fullness with the Constitution of 1978, which brought stability, freedom and progress to contemporary Spain.
