Geography
Aunis is mostly a rolling chalk plain, whose navigable rivers have always been important modes of communication, and from which came economic development and the urbanisation of the region.
The region is coastal, with varied seafronts and offshore islands, from which maritime activities diversified. Nowadays tourism is of great importance.
Geographic framework
Aunis has two river borders, those of the
Sèvre Niortaise

period, characterised by gently rolling hills, where no valley is completely enclosed, and where the land has a regular descent towards the sea. The islands of Ré and Aix were made at the same time and from the same type of rock. The chalk table completes the triangular promontory which juts into the Atlantic, forming the northern extremity of the
Aquitaine Basin.
Large freshwater and seawater marshes have formed in places that have been drained, hardly altering the general relief. The seawater marshes correspond to ancient marine gulfs, made from marine or fluvial sediments. Since the Middle Ages they have been continuously drained by people. In the north, the
Marais Poitevin dries up, at the centre there are the valleys of the small river Curé and its main tributary the Virson and in the east the valley of the Mignon. In the south is the marshland of "Little Flanders" (french: la Petite Flandre), drained since the 17th century. Together these constitute an important reservoir of fresh water, essential for the agricultural and snail-farming activities of the north of the department.
Transport
The geography of the plain was always very unfavourable for communications. The region was almost an enclave, and for a long time on the margins of the French kingdom politically as well as geographically.
[This regional enclave was even more isolated by the marshes () – Marais Poitevin, Marais de Rochefort – which were for much of history obstacles for overland travel]
Huge efforts were made to break this geographical isolation. Without doubt the most spectacular was the coming of the railway in 1857, running from

Industrial diversification

Aunis does not have the strong industrial tradition which is the trademark of regions of the North and of Lorraine, and it was only at the end of the 19th century that factories started to be developed. After World War II, industry in Aunis continued, was reinforced, diversified and brought up-to-date.
Three industrial hubs emerged in Aunis to bring together the industries of Charente-Maritime:

Demography
In 2006 the region had inhabitants,
[That is, the urban area of La Rochelle and the "rural" areas of the Île de Ré, Aunis and Rochefortais] nearly half the total population of Charente-Maritime (47.9%).
In 2010, the northwest of the department had ten of the seventeen towns of over inhabitants, and 31 of the department's 60 communes of over inhabitants.
The region covers , 21.8% of the whole department.
The population density of the region is more than twice that of the departmental average: , compared to for Charente-Maritime as a whole. It is nearly thrice that of the Poitou-Charentes region at and is higher than the national average, which in 2006 was .
The ratio of urban to rural population is comparable to the national average, which is 3:4. This is considerably different from Charente-Maritime as a whole, where the ratio is nearer 3:5.
The region became considerably more urban after World War II, though the population is unevenly distributed. Above all, the Aunis coastal towns have expanded to provide the larger part of employment and leisure.

in 778, the name of ''Aunis'', written as la, Pagus Alnensis, appeared in the last will and testament of Count Roger.
But the etymology of the name has been given many different interpretations and folk etymologies that are still used today. Even so, some people think "The most probable origin is that the town of
Aulnay (Aulnay en
Saintongeais

), which was more important in the Middle Ages than it is today. Aulnay marked the frontier between
Santones and
Pictones. Little by little the province shrank until the frontier was situated a long way from Aulnay. It is the smallest province in France". This interpretation does not pass muster, because there is absolutely no connection between the original names of Aulnay which, in Latin, were written (in 951) or (in 970), so that Aunis, with its older name as seen above, was written or instead . Even now, there is no consensus among historians and etymologists.
Etymologists have proposed three possible interpretations which deserve consideration:
* the name should be linked to the forest, because the french: aulne ( en,

History
In ancient times the region was a long way from civilisation. It was not until the Middle Ages that the province entered history, when La Rochelle sealed its fate and became its capital.

times, the northern part of Santonie,
[ la, Pagus Santonum, "Santone Country"] which became called "Aunis", was a long-neglected region far from civilisation, with no communications.
The old "Forest of Argenson" covered the entire region.
For many centuries this huge forest made a near-impenetrable natural frontier stretching from the rivers

Moreover, the deep sea gulfs (Gulf of Pictones, to the north, Gulf of

Table de Peutinger", where again no Roman road goes into Aunis.
Finally, the valleys of the rivers Curé, Virson, Mignon, and Gères, which were much larger than today, cut deeply through the region's invading forest. But they had the inconvenience of being marshy and prone to floods that turned them into real marshes and bogs, making the region particularly difficult to reach.
All these natural phenomena combined, so that it has been said "this region

Before the Roman conquest around the middle of the 1st century AD, the Celts had a stronghold over the northern shores of the Gulf of Santones. They had even colonised some of the islands in the gulf, which today are part of the Marais ( en, marsh) de Rochefort.
[These comprise the marsh of "la Petite Flandre", drained in the 17th century] The Santones had worked laboriously to perfect a technique of saltwater extraction, and their ancient production sites were put right on the shoreline. These are ("salt sites").
[Thanks to archaeology, dozens of have been found along the ancient shoreline of Aunis, mainly in the area that is now the Marais de Rochefort] These small-scale production sites were particularly numerous in the north of the Gulf of Santones, equally along the coastline, in the deep estuaries, and all around the islands (notably the ÃŽle d'Albe).
[Commune of Muron]
The salt sites were quickly abandoned after the Roman conquest, because the new colonists brought with them a better-performing and more-productive technique for producing salt. Nevertheless, the Romans preferred to have their first salt marshes in the south, notably at
Marennes, and on the banks of the river

During the first three centuries of the Gallo-Roman period, the Romans were especially keen to colonise the area between the coastline of Aunis and the ancient ''sylve d'Argenson'' ("Forest of Argenson"), taking lands latterly in Santone hands. The new colonists, somewhat turning their backs to the sea, set up their – large farms of some dozens of acres, predating the towns themselves – at
Ardillières,
Le Thou,
Ballon, and
Thairé. All these sites left numerous archaeological finds: at Ballon, the remains of a Gallo-Roman villa have been found; at Ardillières, tombs with Gallo-Roman objects have been recovered; at Thou, a Gallo-Roman villa and some coins were discovered in the 19th century.
However, near the end of the 3rd century AD, the entered a new age of prosperity, and its northern part was just as prosperous, after it was integrated into Aquitaine. The Romans also had interests in the "''Pays des Aulnes''" and had started to clear the Forest of Argenson on its eastern border. During the 1st century AD they had built the Roman road connecting (Saintes) to (Angers) but it passed Aunis by, so clearings were opened into this vast forest, notably at
Vouhé. Here remains of a Gallo-Roman villa have been restored, together with many fragmentary finds. At

s. The powerful monasteries, backed up by the lords, helped with the clearings of Aunis in the 11th century. But it is mostly during the 12th and 13th centuries that these earthworks were completed; much later that they became the "plain" of Aunis.
On the coast, the salt waters had become amenable and created Aunis's wealth, and by the end of the 11th century its prosperity was assured. Châtelaillon rapidly became the largest fortified city in Aunis and an important port for the transport of salt from Aunis, and wine from Saintonge.

Birth of the province

In 1374 the King officially separated Saintonge in 1374 and set up Aunis: "''In 1374, Charles V separated La Rochelle from Saintonge to set up a provincial government, comprising the jurisdictions of Rochefort, Marennes and, for a time, Benon. It was thus that Aunis legally became a separate province.''"
The province was much larger in mediaeval times, and underwent numerous changes to its borders. It extended from the
Marais Poitevin in the north, to the lower valley of the
Charente in the south; to the west, it included the islands of
Île de Ré
