The present-day Canton de Vaud (Waadt in German) area has been inhabited since the end of the last Ice Age (10,000).
The Helvetians
The region gained notoriety through Julius Caesar’s mention of the Celtic tribe, the Helvetians, in De Bello Gallico. This tribe also inhabited Vaud from 450 to 58 BC. Tombs have been found in Saint-Sulpice, Vevey, and Vidy.
Caesar mentioned this tribe in connection with their invasion of Gallia. He defeated them in 58 BC at Bibracte, near Autun. Around 44 BC, the Romans founded the city of Nyon (Colonia Julia Equestris). Around 25 BC, Rome conquered the territory of the Celtic tribes, the Nantuates and the Véragres in present-day Chablais and Valais.
Roman era
Aventicum (Avenches), a Celtic oppidum, becomes the capital of the Helvetic tribes. In 71 AD, Aventicum became the Colonia Pia Flavia Constans Emerita Helvetiorum Foederata under Emperor Vespasian (39-81) in the Provincia Belgica. From 89, this area fell under the Provincia Germania Superior.
Romanisation was rapid, first for the cities’ elite, then for the rest of the population. It is known as Gallo-Roman, with Roman and Celtic features.
The region of Vaud was an important trade route, connecting the Rhone, Lake Geneva (Lac Léman), and the passage between the Great St Bernhard Pass and the Jouge Pass, linking Italy and northern Europe.
The Kingdom of Burgundy
The Romans left the area around 400. The Germanic tribe of Burgundians moved into the area and founded the first Kingdom of Burgundy (443-534). However, this Germanic tribe adopted the Gallo-Roman language, the precursor of the French language.
The Franks
Around 534, the Franks occupied the area, known as the pagus waldensis, or the land of the forests. The bishops also make their appearance at this time. The bishop was first based in Avenches and then in Lausanne.
The Romainmôtier monastery dates back to the fifth century, and the Baulmes monastery was founded in the seventh century (this monastery has since disappeared). Monasteries and churches also sprang up in Payerne, Lavaux, Vevey, La Tour-de-Peilz, Saint-Prex, Vernand-Cheseaux, and St-Saphorin.
The Second Kingdom of Burgundy
After the Carolingian Empire (751-888), the area fell under the Second Kingdom of Burgundy (888-1032). Payerne is the city of coronations.
The Holy Roman Empire
The area was part of the Holy Roman Empire from 1032. In the 12th century, the counts of Savoy and Geneva, the bishop of Lausanne, and the duke of Zähringen disputed it. The abbeys play an important political and military role, with Lausanne and Romainmôtier in the lead.
Savoye
From 1207 to 1536, the counts and dukes of Savoy dominated this region. The carrés Savoyards and Chillon Castle date from this time. The Burgundian Wars (1474-1477) were the first significant battles between Savoy and the Confederation, led by Bern and Fribourg.
Savoy allied with the Duke of Burgundy, Charles the Bold (1435-1477), who lost the war and his life. Savoy has to cede some towns (Orbe, Aigle, Ollon, Bex, Ormonts, Echallens, Montagny-sur-Yverdon, Grandson and Morat) to Bern and Fribourg. Bilingualism and later the Catholic and Protestant patchwork of cantons (after 1536) originated here.
Bern
The confederacy violently conquered the whole of Vaud from Savoy in 1536. Leurs Excellences of Bern governed this area by bailiffs. A direct consequence is the Reformation in Vaud, although some communes remained Catholic. The bailiffs’ residences were in Aigle and Payerne.
The area was divided into sixteen Bailliages (Bonmont, Nyon, Aubonne, Morges, Yverdon, Romainmôtier, Lausanne, Orbe-Echallens, Moudon, Oron, Vevey, Aigle, Gessenay, Payerne, Avenches, Grandson).
French era
Napoleon invaded Vaud in late 1797, and on 24 January 1798, Vaud declared itself independent as the République Lémanique. The era of Bern is over.
Napoleon had other plans, however, and on 28 January 1798, he founded the Helvetic Republic, a unitary state without sovereign cantons. On 19 February 1803, the Mediation Act established the new Confederation of 19 cantons, including Vaud.

Le Grand Conseil et le gouvernement du canton du Vaud
1813-1900
In December 1813, this Confederation was again dissolved following the entry of allied Austrian troops. Vaud is one of the twenty-two cantons in the new Confederation of 1815, established in the Federal Treaty (Bundesvertrag, le Pacte fédéral).
Vaud then broadly followed the political developments of the Confederation. The political innovations of 1830-1845 (la Régénération) included universal suffrage for men over 23, elections of municipal (conseil communal, later the municipalité) and cantonal government (Grand Conseil), and the first referendum (droit initiative).
In 1903, Vaud was an industrialised region with several multinational companies (e.g. Nestlé in Vevey) and a wine-growing region (Lavaux). At present, the canton has approximately 300,000 inhabitants; by 2021, this number is expected to rise to around 800,000.
Several cities gained international fame and inhabitants (Montreux, Morges, Nyon, Lausanne, Vevey). Between 1850 and 1890, railways connected all significant places, leading to an increase in tourism and the establishment of numerous Grand Hotels.
One of the country’s oldest golf clubs (founded in 1900) is based in Aigle but is named Golfclub Montreux because the players had their hotel or residence there.
Heraldry
In the new Confederation (1803-1813), the new canton decided on the current green and white flag with the words “Liberté et Patrie”. The miners’ banner in the municipality of Bex inspired the words and the colour white. Green was the colour of the French revolutionaries in 1789; they were considered the liberators in 1798.
Apart from religious texts in certain countries, Switzerland is the only sovereign republic with words on its banner.
