The Neuf pond, dried out, close to Bouligneux in Dombes (May, 2014).

The Dombes (French pronunciation: [dɔ̃b] (listen); Arpitan: Domba) is an area in eastern France, once an independent municipality, formerly part of the province of Burgundy, and now a district comprised in the department of Ain, and bounded on the west by the Saône River, on the south by the Rhône, on the east by the Ain and on the north by the district of Bresse.^[1]

Topography[]

The region forms an undulating plateau with a slight slope towards the north-west, the higher ground bordering the Ain and the Rhône attaining an average height of about 1,000 ft (300 m). The Dombes is characterized by an impervious surface consisting of boulder clay and other relics of glacial action. Because of this, there are a large number of rain-water pools, varying for the most part from 35 to 250 acres (1.0 km²) in size which cover some 23,000 acres (93 km²) of its total area of 282,000 acres (1,140 km²). These pools, artificially created, date in many cases from the 15th century, some to earlier periods, and were formed by landed proprietors who in those disturbed times saw a surer source of revenue in fish-breeding than in agriculture.^[1]

Disease and depopulation resulted from this policy and at the end of the 18th century the Legislative Assembly decided to reduce the area of the pools which then covered twice their present extent. Drainage works were continued, roads cut, and other improvements effected during the 19th century; partly as a result of Napoleon III's installation of Trappist monks in the district to set about the task. Large numbers of fish, principally carp, pike, and tench are still reared profitably. The pools are periodically dried up so the ground can be cultivated.^[1]

Political history[]

Double tournois coin, 1622, copper. Sovereign principality of the Dombes, Maria de Bourbon-Montpensier.

The Dombes [1] (Latin Dumbae) once formed part of the Kingdom of Burgundy-Arles. In the 11th century, when the kingdom began to break up, the northern part of the Dombes came under the power of the lords of Bâgé, and in 1218, by the marriage of Marguerite de Baugé with , passed to the lords of Beaujeu. The southern portion was held in succession by the lords of Villars and of . Its lords took advantage of the excommunication of Frederick II, Holy Roman Emperor to assert their complete independence of the Holy Roman Empire.^[1]

In 1400, Louis II, Duke of Bourbon, acquired the northern part of the Dombes, together with the lordship of Beaujeu, and two years later bought the southern part from the sires de Thoire, forming the whole into a new sovereign principality of the Dombes, with Trévoux as its capital.^[1]

The principality was confiscated by King Francis I of France in 1523, along with the other possessions of the Constable de Bourbon, was granted in 1527 to the queen-mother, Louise of Savoy, and after her death was held successively by kings Francis I, Henry II and Francis II, and by Catherine de' Medici. In 1561 it was granted to Louis, duc de Montpensier, by whose descendants it was held till, in 1682, Anne Marie Louise of Orléans, the duchess of Montpensier, gave it to Louis XIV's bastard, the Duke of Maine, as part of the price for the release of her lover Lauzun.^[1]

The eldest son of the duke of Maine, Louis-Auguste de Bourbon (1700–1755), prince of Dombes, served in the army of Prince Eugene of Savoy against the Turks (1717), took part in the War of the Polish Succession (1733–1734), and in that of the Austrian Succession (1742-1747). He was made colonel-general of the Swiss regiment, governor of Languedoc and master of the hounds of France. He was succeeded, as prince of Dombes, by his brother the count of Eu, who in 1762 surrendered the principality to the crown. The little principality of Dombes showed in some respects signs of a vigorous life; the prince's mint and printing works at Trévoux were long famous, and the college at Thoissey was well endowed and influential.^[1]

Summary[]

Taking the above information from 1911 with that from other sources, we seem to have a district composed of glacial till, from a period when the Alpine ice sheet extended over the area, probably from the Mindel and Riss glacials. This appears to be mainly clay deposited in situ as the ice melted. There appears to be also, sand and gravel on the clay in places. This may date from the latest glacial, the Würm.

The clay till which also goes by the now rather old-fashioned but still useful name of boulder clay, is usually very sticky when wet and hard when thoroughly dry. This made arable use of the land with medieval implements impossible and it was unsuitable for pasture most of the time. Usually, such land was left as woodland but here, enterprising landowners seem to have taken it on when nobody else wanted it and attempted to make it produce income by excavating lakes for fish farming.

This was a sensible, commercial idea except in that the open, still and shallow water will have harboured the vectors of malaria. The population therefore remained small and probably sickly, until more effective, 19th century drainage permitted use of some of the land for pasture and modern agricultural methods permitted the heavier land to be used for ploughing. In parallel with these, medical advances overcame the malaria. Since the mid 20th century, the district has become fairly prosperous and the INSEE statistics now indicate a steady climb in population numbers.

Communes in the Dombes[]

The borders of the Dombes are not sharply defined, especially not towards the north where it continues into the Bresse. The Dombes plateau proper does not include the escarpments (e.g. Côtière) and the plains along the rivers Saône, Rhône and Ain.^[2] The communes in the wider Dombes region cooperate in several intercommunalities: (36 communes, seat in Châtillon-sur-Chalaronne),^[3] (19 communes, seat in Trévoux),^[4] and part of the Communauté d'agglomération du Bassin de Bourg-en-Bresse^[5] (indicated "CAB" in the table below).
