Cádiz and the Constitution of 1812
When Europe's oldest city invented modern freedom
📱 1 to 10 phones · 1 team per phone · Independent codes
Founded by the Phoenicians around 1100 BCE, Cádiz is the oldest city in Western Europe. In 1812, besieged by Napoleon, it voted the first liberal constitution of Spain — "La Pepa" — which inspired revolutions across Latin America. Three thousand years of history on a peninsula battered by the Atlantic.
Three thousand years facing the ocean
Cádiz is a geographical anomaly: a city built on a peninsula so narrow that you can see the ocean from almost every street. The Phoenicians called it Gadir — "the fortress." The Romans made it Gades, Julius Caesar's home port. In the 18th century, after Seville lost its monopoly on trade with the Americas, Cádiz became Spain's richest port. But its political finest hour was 1812, when the Cortes, sheltering in the city besieged by Napoleonic troops, voted the first liberal constitution of the Hispanic world.
« "Cádiz is a ship anchored in the Atlantic. If the isthmus were cut, it would sail to the Americas." »— — On the Malecón, facing the Atlantic that made and unmade Cádiz's fortune
From Phoenician Gadir to La Pepa of 1812
Around 1100 BCE, the Phoenicians of Tyre founded Gadir — probably the oldest city in Western Europe. They built a temple to Melqart there, said to have contained the Pillars of Hercules. The Romans made it a strategic port; Julius Caesar received his first magistracy there in 69 BCE and reportedly wept before a statue of Alexander the Great, regretting he had achieved nothing at his age.
In the 18th century, Cádiz replaced Seville as the port of the trade monopoly with the Americas. New World fortunes built the watchtowers — those turrets crowning merchants' houses from which the arrival of galleons was watched. The Torre Tavira, the most famous, still offers a 360-degree view of the city and the bay.
In 1810, while Napoleon occupied nearly all of Spain, Cádiz remained impregnable thanks to its maritime position. The Spanish Cortes took refuge there and, on 19 March 1812 — Saint Joseph's day, hence the nickname "La Pepa" — promulgated Spain's first liberal constitution. This revolutionary text — national sovereignty, separation of powers, freedom of the press — would inspire the constitutions of all Latin America.
