It takes its present name from the name of the dominant Gallo-Celtic tribe in the region, the Parisii. At least that’s what the Romans called them when they showed up in 52 BCE and established their city Lutetia on the left bank of the Seine, in what is now called the “Latin Quarter” in the 5th arrondissement.
The Romans held out here for as long as anywhere else in the Western Empire, but by 508 CE they were gone, replaced by Clovis of the Franks, who is considered by the French to have been their first king.
Clovis’ descendants, aka the Carolingians, held onto the expanded Lutetian state for nearly 500 years through Viking raids and other calamities, which finally resulted in a forced move by most of the population back to the islands which had been the center of the original Celtic village.
The Capetian Duke of Paris was voted to succeed the last of the Carolingians as King of France, ensuring the city a premier position in the medieval world. Over the next several centuries Paris expanded onto the right bank into what was and is still called le Marais (The Marsh). Quite a few buildings from this time can be seen in the 4th arrondissement.
The medieval period also witnessed the founding of the Sorbonne. As the “University of Paris”, it became one of the most important centers for learning in Europe — if not the whole world, for several hundred years. Most of the institutions that still constitute the University are found in the 5th, and 13th arrondissements.
In the late 18th century, there was a period of political and social upheaval in France and Europe, during which the French governmental structure, previously a monarchy with feudal privileges for the aristocracy and Catholic clergy, underwent a radical change to forms based on Enlightenment principles of nationalism, citizenship, and inalienable rights.
Notable events during and following the revolution were the storming of the Bastille 4th arrondissements, and the rise and fall of Napoleonic France. Out of the violent turmoil that was the French Revolution, sparked by the still known Passion des Français, emerged enlightened modern-day France.
The Paris of today was built long after the Capetian and later the Bourbon Kings of France made their mark on Paris with the Louvre and the Palais Royal, both in the 1st.
In the 19th century, Baron von Hausmann set about reconstructing the city, by adding the long straight avenues and replacing many of the then existing medieval houses, with grander and more uniform buildings.
