Toulouse ( , ; ) is a city in Southern France, the prefecture of the Haute-Garonne department and of the Occitania region. The city is on the banks of the River Garonne, from the Mediterranean Sea, from the Atlantic Ocean and from Paris. It is the fourth-largest city in France after Paris, Marseille, and Lyon, with 514,819 inhabitants within its municipal boundaries (2023); its metropolitan area has a population of 1,529,112 inhabitants (2023). Toulouse is the central city of one of the 22 metropolitan councils of France. Between the 2014 and 2020 censuses, its metropolitan area was the third fastest growing among metropolitan areas larger than 500,000 inhabitants in France.

Toulouse is the centre of the European aerospace industry, with the headquarters of Airbus, the SPOT satellite system, ATR and the Aerospace Valley. It hosts the CNES's Toulouse Space Centre (CST) which is the largest national space centre in Europe, but also, on the military side, the newly created NATO space centre of excellence and the French Space Command and Space Academy. Safran, Thales Alenia Space, Airbus Defence and Space, Collins Aerospace and Liebherr-Aerospace also have a significant presence in Toulouse.

The air route between Toulouse–Blagnac and the Parisian airports is the busiest in France, transporting 3.2 million passengers in 2019. According to the rankings of and Challenges, Toulouse is the most dynamic French city. L'ExpressLes villes les plus dynamiques de France Challenges La Dépêche du Midi

Founded by the Romans, the city was the capital of the Visigothic Kingdom in the 5th century and the capital of the province of Languedoc in the Late Middle Ages and early modern period (provinces were abolished during the French Revolution), making it the unofficial capital of the cultural region of Occitania (Southern France). It is now the capital of the administrative region of Occitania, the second largest region in Metropolitan France.

The University of Toulouse is one of the oldest in Europe (founded in 1229). Toulouse is also the home of prestigious higher education schools, notably in the field of aerospace engineering. Together with the university, they have turned Toulouse into the fourth-largest student city in France, with a university population of nearly 140,000 students.

Toulouse has three UNESCO World Heritage Sites: the Canal du Midi was designated in 1996 and shared with other cities. The Basilica of St. Sernin, the largest remaining Romanesque building in Europe, Europe Close was designated in 1998 along with the former hospital Hôtel-Dieu Saint-Jacques because of their significance to the Santiago de Compostela pilgrimage route. The city's unique architecture, made of pinkish terracotta bricks, has earned Toulouse the nickname ("The Pink city"). In 2023, Toulouse was named a UNESCO City of Music, joining UNESCO's Creative Cities Network.

Geography Toulouse is in the south of France, north of the department of Haute-Garonne, on the axis of communication between the Mediterranean Sea and the Atlantic Ocean. The city, which is about 80 km/50 mi from the Pyrenees, borders with Andorra and Spain.

Hydrography The city is traversed by the Canal de Brienne, the Canal du Midi, the Canal de Garonne and the rivers Garonne, Touch and Hers-Mort.

Climate Toulouse has a four-season humid subtropical climate (Cfa in the Köppen climate classification). Too much precipitation during the summer months prevents the city from being classified in the Mediterranean climate zone.

History

Early history The Garonne Valley was a central point for trade between the Pyrenees, the Mediterranean and the Atlantic since at least the Iron Age. The historical name of the city, Tolosa (Τολῶσσα in Greek, and of its inhabitants, the Tolosates, first recorded in the 2nd century BC), is of unknown meaning or origin, possibly from Aquitanian or Iberian,Albert Dauzat et Charles Rostaing, Dictionnaire étymologique des noms de lieux en France, 2nd ed., Librairie Guénégaud 1978. but it has also been connected to the name of the Gaulish Volcae Tectosages,Le Nom de Toulouse de Pierre Moret, 1996, Université Toulouse le Mirail – Toulouse II, p. 11; Histoire de Toulouse, 1974, p. 11. or to the same root as Irish tulach or Welsh twlch, (little hill).

Toulouse refounded by the Romans on the banks of the Garonne Tolosa enters the historical period in the 2nd century BC, when it became a Roman military outpost. After the conquest of Gaul, it was developed as a Roman city in Gallia Narbonensis. Under the reign of Emperor Augustus and thanks to the Pax Romana, the Romans moved the city a few kilometres from the hills where it was an oppidum to the banks of the Garonne, which were more suitable for trade.Collective work directed by Jean-Marc Olivier and Rémy Pech: "Histoire de Toulouse et de la métropole". Éditions Privat, 2019.

In the second half of the 1st century, the emperor Domitian distinguished Toulouse by placing it under the patronage of the goddess Pallas Athena, so that the Latin poets Martial, Ausonius and Sidonius Apollinaris called the city Palladia Tolosa (Palladian Toulouse), a term that was still used in the Renaissance and even today when the city is presented as propitious to the arts and letters.

Around the year 250, Toulouse was marked by the martyrdom of Saturnin, the first bishop of Toulouse. This episode illustrates the difficult beginnings of Christianity in Roman Gaul.

Capital of the Visigothic Kingdom In the 5th century, Toulouse fell to the Visigothic kingdom and became one of its major cities, even serving as its capital, before it fell to the Franks under Clovis in 507 during the Battle of Vouillé. From that time, Toulouse was the capital of Aquitaine within the Frankish realm.

Under Frankish rule In 721, Duke Odo of Aquitaine defeated an invading Umayyad Muslim army at the Battle of Toulouse. Many Arab chroniclers consider that Odo's victory was the real stop to Muslim expansion into Christian Europe, incursions of the following years being simple raids without real will of conquest (including the one that ended with Charles Martel's victory at the Battle of Tours, also called the Battle of Poitiers).

The Frankish conquest of Septimania followed in the 750s, and a quasi-independent County of Toulouse emerged within the Carolingian sub-kingdom of Aquitaine by the late 8th century. The Battle of Toulouse of 844, pitting Charles the Bald against Pepin II of Aquitaine, was key in the Carolingian Civil War.

County of Toulouse

Charlemagne had created the county of Toulouse in 778 to guard the border of Muslim Spain, but the disintegration of the kingdom of Aquitaine and the weakness of royal power in the following centuries led to the de facto independence of the county of Toulouse and many provinces.

In the 11th and 12th centuries, southern France was still steeped in Latin culture. Unlike the north of France, justice followed written Roman law and the nobles were highly educated. This was the time of the troubadours who wrote their poetry in Occitan (called "Provençal" at the time), then one of the most sophisticated languages in Europe. Like the other great lords of the Midi, the counts of Toulouse maintained and favoured these poets, this is how Count Raymond V employed for some time the famous Bernard de Ventadour, expert in singing courtly love.Pyrénées Toulouse Gers, Le Guide Vert Michelin, 2016.

In 1096, Raymond IV, Count of Toulouse, left with his army at the call of the Pope Urban II to join the First Crusade, of which he was one of the main leaders. This exodus of its warriors and nobles, reinforced by the creation of the faraway County of Tripoli by Raymond IV at the beginning of the 12th century, weakened the city militarily as well as the ascendancy that its counts had over it. The Duke William IX of Aquitaine challenged the possession of the city on the grounds that it should have been inherited by his wife Philippa (daughter of the previous count of Toulouse, whereas Raymond IV was only his brother). More than 50 years later his granddaughter Eleanor of Aquitaine still claimed the inheritance in vain.

In the 12th century the city left its Roman limits and a new district developed around the church of Saint-Sernin: the Bourg. The church of Saint-Sernin was famous and revered for its many relics, and the chapter of its canons, which had possessions as far away as Spain, was powerful enough to free itself from the control of the bishop of Toulouse. This dissent had important local political repercussions, making the Bourg in practice a separate district from the city. In 1152, the notables of Toulouse took advantage of a weakening of the county power to obtain for their city a great autonomy, they created a municipal body of consuls, called capitouls in Toulouse, to lead the city. The Bourg, which had only a quarter of the inhabitants of Toulouse, obtained as many capitouls as the rest of the city. Economically, Toulouse, which was at the center of a large cereal-growing plain, was distinguished by its numerous mills that took advantage of the force of the Garonne, among which the Bazacle Milling Company was the first recorded European joint-stock company.

The fight against Catharism and its various aspects At the beginning of the thirteenth century the County of Toulouse was caught up in another crusade that would last twenty years (1209–1229), of which it was the target this time. The reason for this was the development of Catharism in the south of France, which the Pope Innocent III wanted to eradicate by all possible means.

After an initial victory of the crusaders led by Simon de Montfort who defeated the combined forces of Count Raymond VI of Toulouse and King Peter II of Aragon at the Battle of Muret, the following years saw the fate of the county of Toulouse swing alternately in favour of one party or the other. Finally, a late intervention by King Louis VIII of France in 1226 tipped the balance in favour of the crusaders, resulting in the submission of Count Raymond VII to the French Crown and the end of the independence of the County of Toulouse.

But beyond the military crusade, this struggle took on several important aspects for the city of Toulouse:  The Dominican Order was founded in Toulouse by Saint Dominic in 1215. Spanish priest Dominic de Guzmán wanted to convert the Cathars to Catholicism peacefully, by preaching and by living a poor and exemplary life. After years of criss-crossing the Lauraguais countryside between Carcassonne and Toulouse, he changed his method and decided to preach in town. In 1215 he settled in Toulouse and founded a mendicant order which, within a few decades, would cover Europe with hundreds of convents: The Order of Preachers, also known as the Dominicans. Under the impulse of the bishop of Toulouse, Foulques, an original and austere architectural style was born in Toulouse, designed to break with the display of luxury of the Catholic church which drove the faithful towards the Cathars: the Southern French Gothic. In the Treaty of Paris of 1229, Toulouse formally submitted to the crown of France. The county's sole heiress Joan was engaged to Alphonse, Count of Poitiers, a younger brother of Louis IX of France. The marriage became legal in 1241, but it remained childless and so after Joan's death, the county fell to the Crown of France by inheritance. Another consequence of the Treaty of Paris was the creation of the University of Toulouse, established on the Parisian model, strongly sponsored by the pope and intended as a means to dissolve the heretic movement. Also in 1229, the Council of Toulouse was held, which laid the foundations for the long period of Inquisition that was to eradicate Catharism in the region after the military victory of the Crusade.
