Liège (, lee-EZH, lee-AYZH; French: [ljɛʒ] ; Walloon: Lîdje [liːtʃ]; Dutch: Luik [lœyk] ; German: Lüttich [ˈlʏtɪç] ) is a city and municipality in the Belgian region of Wallonia, and the capital of the eponymous province. The city is situated in the valley of the Meuse, in the east of Belgium, not far from borders with the Netherlands (Maastricht is about 33 km (20.5 mi) to the north) and Germany (Aachen is about 53 km (32.9 mi) north-east). In Liège, the Meuse meets the river Ourthe. The city is part of the sillon industriel, the former industrial backbone of Wallonia. It is still the principal economic and cultural centre of the region.
The municipality consists of the following sections (sub-municipalities): Liège proper, Angleur, Bressoux, Chênée, Glain, Grivegnée, Jupille-sur-Meuse, Rocourt, and Wandre. In January 2026, Liège had 198,102 inhabitants. The metropolitan area, including the outer commuter zone, covers an area of 1,879 km2 (725 sq mi) and had a total population of 749,110 on 1 January 2008. This includes a total of 52 municipalities, such as Herstal and Seraing. Liège ranks as the third most populous urban area in Belgium, after Brussels and Antwerp, and the fourth most populous municipality after Antwerp, Ghent and Charleroi. The city is part of the Euregio Meuse-Rhine.
The name is of Germanic origin and is reconstructible as *liudik-, from the Germanic word *liudiz "people", which is found in for example Dutch lui(den), lieden, Polish ludzie, Czech lidé, German Leute, Old English lēod (English lede), Icelandic lýður ("people"), Latvian ļaudis ("people"), Lithuanian liaudis ("people"). It is found in Ukrainian as liudy ("people"), in Russian as люди, romanised: lyudi ("people"), in Latin as Leodicum or Leodium, and in Middle Dutch as ludic or ludeke.
Until 17 September 1946, the city's name was written Liége, with the acute accent instead of a grave accent. This change is in conformity with changes in spelling other words from -ége to -ège (e. g. collège), which was made in the seventh edition of the Dictionnaire de l'Académie française (1878) to reflect a change in the pronunciation from the closed vowel [e] to the open vowel [ɛ]. This official change did not extend to the demonym, which persists as Liégeois/Liégeoise.
In French, Liège is associated with the epithet la cité ardente ("the fervent city"). This term, which emerged around 1905, originally referred to the city's history of rebellions against Burgundian rule, but was appropriated to refer to its economic dynamism during the Industrial Revolution.
Although settlements already existed in Roman times, the first references to Liège are from 558, when it was known as Vicus Leudicus. Around 705, Saint Lambert of Maastricht is credited with completing the Christianization of the region, indicating that up to the early 8th century the religious practices of antiquity had survived in some form. Christian conversion may still not have been quite universal, since Lambert was murdered in Liège and thereafter regarded as a martyr for his faith. To enshrine St. Lambert's relics, his successor, Hubertus (later to become St. Hubert), built a basilica near the bishop's residence which became the true nucleus of the city.
A few centuries later, the city became the capital of a prince-bishopric, which lasted from 985 till 1794. The first prince-bishop, Notger, transformed the city into a major intellectual and ecclesiastical centre, which maintained its cultural importance during the Middle Ages. Pope Clement VI recruited several musicians from Liège to perform in the Papal court at Avignon, thereby sanctioning the practice of polyphony in the religious realm. The city was renowned for its many churches, the oldest of which, St Martin's, dates from 682. Although nominally part of the Holy Roman Empire, in practice it possessed a large degree of independence.
Late medieval and early modern periods
The strategic position of Liège has made it a frequent target of armies and insurgencies over the centuries. It was fortified early on with a castle on the steep hill that overlooks the city's western side. During this medieval period, three women from the Liège region made significant contributions to Christian spirituality: Elizabeth of Spalbeek, Christina the Astonishing, and Marie of Oignies.
In 1345, the citizens of Liège rebelled against Prince-Bishop Engelbert III de la Marck, their ruler at the time, and defeated him in battle near the city. Shortly after, a unique political system formed in Liège, whereby the city's 32 guilds shared sole political control of the municipal government. Each person on the register of each guild was eligible to participate, and each guild's voice was equal, making it the most democratic system that the Low Countries had ever known. The system spread to Utrecht, and left a democratic spirit in Liège that survived the Middle Ages.
At the end of the Liège Wars, a rebellion took place against rule from Burgundy. In 1468 Duke Charles the Bold of Burgundy, witnessed by King Louis XI of France, captured and largely destroyed the city after a bitter siege which was ended with a successful surprise attack. The rebellion figures prominently in the plot of Sir Walter Scott's 1823 novel Quentin Durward.
The Prince-Bishopric of Liège was technically part of the Holy Roman Empire which, after 1477, came under the rule of the Habsburgs. The reign of prince-bishop Érard de La Marck (1506–1538) coincides with the dawn of the Renaissance.
During the Counter-Reformation, the diocese of Liège was split and progressively lost its role as a regional power. By the 17th century, the bishopric of Liège became a virtual Secundogeniture of the Bavarian royal house of Wittelsbach, with second sons of the Bavarian monarch ruling as prince-bishop. Beginning with the ascension of Ernest of Bavaria in 1581, Bavarian princes ruled over Cologne, Münster, and other bishoprics in the northwest of the Holy Roman Empire in addition to Liège. Ferdinand of Bavaria (bishop) ruled from 1612 to 1650, and Maximilian Henry of Bavaria ruled from 1650 to 1688.
In 1636, during the Thirty Years' War, the city was besieged by Imperial forces under Johann von Werth from April to July. The army, mainly consisting of mercenaries, extensively and viciously plundered the surrounding bishopric during the siege.
An Anglo-Dutch army under the Duke of Marlborough and Menno van Coehoorn captured the city in 1702 from the Bavarian prince-bishop and his French allies in 1702 during the War of the Spanish Succession.
In the middle of the eighteenth century the ideas of the French Encyclopédistes began to gain popularity in the region. Bishop François-Charles de Velbrück (1772–84), encouraged their propagation, thus prepared the way for the Liège Revolution which started in the episcopal city on 18 August 1789 and led to the creation of the Republic of Liège before it was invaded by counter-revolutionary forces of the Habsburg monarchy in 1791.
In the course of the 1794 campaigns of the French Revolution, the French Revolutionary Army took the city and imposed strongly anticlerical regime, destroying St. Lambert's Cathedral. The overthrow of the Prince-Bishopric of Liège was confirmed in 1801 by the Concordat co-signed by Napoléon Bonaparte and Pope Pius VII. France lost the city in 1815 when the Congress of Vienna awarded it to the United Kingdom of the Netherlands. Dutch rule lasted only until 1830, when the Belgian Revolution led to the establishment of an independent, Catholic and neutral Belgium which incorporated Liège. After this, Liège developed rapidly into a major industrial city which became one of continental Europe's first large-scale steel making centres. The Walloon Jacquerie of 1886 saw a large-scale working class revolt. No less than 6,000 regular troops were called into the city to quell the unrest, while strike spread through the whole sillon industriel.
Liège's fortifications were redesigned by Henri Alexis Brialmont in the 1880s and a chain of twelve forts was constructed around the city to provide defence in depth. This presented a major obstacle to the Imperial German Army in 1914, whose Schlieffen Plan relied on being able to quickly pass through the Meuse valley and the Ardennes en route to France. The German invasion of Belgium on 5 August 1914 soon reached Liège, which was defended by 30,000 troops under General Gérard Leman in the Battle of Liège. The forts initially held off General Alexander von Kluck's German First Army of about 100,000 men but were pulverised into submission by a five-day bombardment by heavy artillery, including thirty-two 21 cm mortars and two German 42 cm Big Bertha howitzers. Due to faulty planning of the protection of the underground defence tunnels beneath the main citadel, one direct artillery hit caused a huge explosion, which eventually led to the surrender of the Belgian forces. The Belgian resistance was shorter than had been intended, but the twelve days of delay caused by the siege nonetheless contributed to the eventual failure of the German invasion of France. The city was subsequently occupied by the Germans until the end of the war. Liège received the Légion d'Honneur for its resistance in 1914.
