was supported by the French government throughout the 18th century and the first half of the 19th century. In 1789, the old feudal system was dismantled, and Amanlis, along with all other rural parishes in France, became a commune with an elected mayor and municipal government. The commune of Amanlis was separated from Châteaugiron and became part of the canton of Janzé. After the surrender of Napoleon to the British in 1815 and the return of peace to Europe, the exportation of sailcloth again became important to the prosperity of Amanlis. However, the local fabricators kept to their traditional methods of production, and they were unable to compete with mechanized techniques used by their competitors in Rennes, other cities in northern France, Great Britain and Belgium. Prices fell, and by 1870, the textile industry was in a serious downturn. Two other problems contributed to the declining fortunes of the commune. The first was the lack of good roads, which made it difficult to hold markets in Amanlis. The second was the inefficient configuration of typical farms, which were characterized by very small fields scattered about the countryside. At the turn of the 20th century, the fields of hemp had been replaced by grasslands, the number of cattle doubled, and new species of apple trees were being planted. In addition, the production of grain was increasing due to mechanization. New means of transportation (rail, automobiles, bicycles) allowed people to travel to Rennes and beyond. Soldiers in World Wars I and II returned to Amanlis with new ideas and an interest in new ways of doing things. As of 2020, the agricultural output of the commune was approximately 48% dairy products, 19% livestock, 16% poultry, and 16% plant-based. Language and Culture The traditional culture of Brittany remains important to the inhabitants of the region. Before the introduction of compulsory education in French, the Breton language was widely spoken in the western part of the region, while the Latinate Gallo language was typically spoken in the eastern part around Rennes, which includes Amanlis. Gallo is currently spoken by some 28,000 people, mostly in rural areas. Population The manufacturing of sailcloth after 1500 required significant manpower, and the population of Amanlis doubled from 1,000 to 2,000 within a hundred years. It continued to increase for some time, but a series of wars, bad harvests, famine and high taxes led to reduced production of sailcloth,
