Nantes was named after Nantes, and Nantes, the earliest branch of Gaul, built its capital here. Under the rule of the Roman Empire, Nantes became a commercial center. According to written records, the indigenous people here are Celts (Gauls or bretons). Romans, Franks and Normans all occupied this area one after another. In A.D. 1532, this place was formally incorporated into the Kingdom of France. The Normans occupied Nantes from 834 to 936. In the Middle Ages, Nantes had a long-term struggle with Rennes for the sovereignty of Brittany Peninsula.

After the religious war, Nantes joined the Catholic League and took refuge in King Henry IV of the French Republic. In A.D. 1598, Henry of Navarra, the French king, issued the famous edict of Nantes here, which guaranteed religious tolerance in the form of law for the first time in European history after the Roman Empire. As a result, Nantes became famous in human history and Protestants were liberated. During the Revolution of the French Republic, the Revolutionary Committee in Nantes was ruthlessly suppressed. It was occupied by Germany during World War II. Nantes was partially destroyed during World War II. After World War II, large-scale reconstruction began, people filled rivers and roads, and railways passed through the city center. The port is gradually recovering. Under the unified planning of the country, Nantes has become the center of economic development. In the late 20th century, industry began to rise. The port has a 3-kilometer-long dock area, and the river channel has been dredged for large ships to pass through, which is complementary to the port of St. Nazaire.

Originally a town of Celtic tribe named Namnetti, it appeared in the first 70 years. Later, Caesar captured it in the first 56 years and named it Portus Namnetus. Nantes was subsequently invaded by Saxons (about 285 years), Franks (about 500 years) and Britten (6th and 7th centuries). The Normans destroyed Nantes in 843: "After many years, Nantes is still barren, dilapidated and full of thorns." In 937, Aaron II (grandson of Aaron I, the last king of Brittany) expelled the Vikings who occupied Brittany and became the first duke of Brittany.

From 65438 to 0956, France carried out a new round of administrative reform. Nantes and the whole Atlantic Loire province are divided into Loire River.

Many debates revolve around the continuation of this change and oppose the division caused by the non-elected government, because the Loire province in the Atlantic Ocean belongs to Brittany in culture, history and geography. Language issues are also very important. In eastern Brittany, French and derived languages, such as Gaul, have a greater influence than Brittany. However, in many big cities, including Nantes and Sao Paulo, Brittany is always widely used. In recent years, in order to attract tourists, bilingual plaques have appeared in this city.
