Neighboring communes edit

During the Roman era, Tonnerre was known as Tornodurum, which was derived from the Lingone word for "fortress". It was the capital of Pagus Tornodorensis. Here, in the valley of the Armançon, the County of Tonnerre was created, which served as a point of passage between Paris and Dijon, during a time when the King of France had designs on the Duchy of Burgundy.

Three etymologies of Tonnerre are rooted in the Celtic era: it is derived from Torn, an obscure local deity; others claim it is from Douros, meaning fortress; yet others say it is connected to a place near the torrent. It is equally likely that the three solutions are one:

• In 1782, newly discovered caves yielded weapons, ornaments, coins, and jewelry linked to the worship of deities.
• The dominant fortress of Tonnerre was located upon the sites "Mont Bellant" and "Vieux Châteaux" which yield many ancient artifacts.
• Amongst the overwhelming evidence of the area's religious heritage is the Fosse Dionne.

Antiquity edit

In 2005, research at a place called Les Petits Ovis revealed that the site was occupied by a necropolis dating to the end of the Bronze Age. At a place called Terre de Vauplaine burials and cremations from the Bronze Age to the Iron Age have been found.

An oppidum dating to the La Tène period developed on the high part of the City of Tonnerre. Later, a rural Roman Gaul settlement was built whose boundaries are not well-established.

Medieval county edit

During this period many tanneries appeared along the banks of the Armançon or near the Fosse Dionne.

Dynasty of the native counts edit

Tonnerre was the seat of a County starting in the 10th century. They administered the western edge of the vast bishopric of Langres. Several members of this family rose to rule this bishopric. Its seat may have been in the Bar-sur-Seine area. The counts, known by the charters of the Abbey of Saint-Michel, bear the name Miles. Succession in the 11th century was more chaotic.

A viscount of Tonnerre appeared at the beginning of this century. Under the law, this meant that the owner of the county had rights to other land as well, which imposes the establishment of a viscount (the same problem arose in Joigny in 1080). This viscount was the origin of the Rougemont family.

The last heir to this dynasty was the wife of Guillaume the 11th-century Count of Nevers and Auxerre. Guillaume had great difficulty surviving under the tutelage of his uncle, the Duke of Burgundy who killed his father. The marriage of his younger sister to a son of the Count of Brienne provoked the definitive separation of Tonnerre from the County of Bar-sur-Seine.

Dynasty of Nevers-Auxerre (1045–1193) edit

Guillaume de Nevers ruled the county for a long period of time. A provost became the representative of the administration to the Tonnerrois. The tendency of heredity in comital succession is an admitted weakness. The younger son of Guillaume nearly caused an autonomous county to emerge. The county frequently served as dower to dowager countesses. Some families wield great power in the county; especially the Argenteuil and Rougemont families. Some of them were bestowed with the title of viscount due to profitable commercial ventures in Ligny-le-Chatel. This phenomenon touched other parts of the county as well. The lords of Noyers-sur-Serein evaded comital authority and established an independent hold on the border of Auxerre County and former county of Avallon. Feudalism had reached its peak. By the end of this period the city of Tonnerre had grown considerably. The city had two parishes: Notre-Dame and Saint-Pierre. Around 1170, the counts attempted to reassert control of their powerful feudal lords, but only had limited success: they imposed an inheritance tax. Feudalism was deeply entrenched.

Dynasty of Courtenay edit

From the late 12th to middle of the 13th century, the city of Tonnerre was the most important community in the County of Nevers-Auxerre and Tonnerre. This period came to an end after the count's business misadventures in the Byzantine Empire. Copying an institution in place in royal domains since 1184, the count divided his dominion into two bailiwicks, both administered by the same bailey. The bailey was largely ineffectual. It could not reign in the powerful local feudal lords, clashed with the bishop of Auxerre and lead to the revolt of Hervé de Donz; all which humiliated Count Pierre de Courtenay. The head of a junior branch of the de Courtenay came to rule the seigniory of Tanlay.

Dynasty of Chalon (1308–1463) edit

In the middle of the 13th century, a countess of Tonnerre married the King of Sicily. She founded the Grand Hotel-Dieu: the largest civil monument in Burgundy.

After participating in the division of the County of Nevers-Auxerre and Tonnerre, the Chalon family was given the County of Tonnerre.

As a prelude to the second phase of the Hundred Years' War, the Count of Tonnerre removed a lady-in-waiting from the court of the Duchess of Burgundy. Jean Sans Peur used this as a pretext to wage war against the Count of Tonnerre. Despite the vast difference in the size of their armies, the count managed to delay his ruin. This desperate struggle had a price: the Tonnerrois region was ravaged. The estates of the feudal lords who followed their natural suzerain into battle were plundered by Burgundian nobles. The war between Armagnacs and Burgundians occurred soon afterwards (1411). Tonnerre remained under the control of the Duchy of Burgundy. During the 15th century, the city received new tax institutions: Aids and the Election.

French Revolution edit

It was the capital of the Tonnerre District from 1790 to 1795 and the Arrondissement of Tonnerre from 1800 to 1826.

World War II edit

The city was the victim of German bombing in June 1940 and Allied bombing on 25 May 1944, which killed 14 people when a church was hit.

In 2017, the commune had 4,575 inhabitants, a change of −13% from 2007.
