Aosta

Aosta was settled in proto-historic times and later became a centre of the Salassi, many of whom were killed or sold into slavery by the Romans in 25 BC. The campaign was led by Terentius Varro, who then founded the Roman colony of Augusta Praetoria Salassorum, housing 3,000 retired veterans. After 11 BC Aosta became the capital of the Alpes Graies ("Grey Alps") province of the Empire. Its position at the confluence of two rivers, at the end of the Great and the Little St Bernard Pass, gave it considerable military importance, and its layout was that of a Roman military camp.

After the fall of the Western Empire, the city was conquered, in turn, by the Burgundians, the Ostrogoths, and the Byzantines. The Lombards, who had annexed it to their Italian kingdom, were expelled by the Frankish Empire under Pepin the Short. Under his son, Charlemagne, Aosta acquired importance as a post on the Via Francigena, leading from Aachen to Italy. After 888 AD it was part of the renewed Kingdom of Italy under Arduin of Ivrea and Berengar of Friuli.

In the 10th century Aosta became part of the Kingdom of Burgundy. After the fall of the latter in 1032, it became part of the lands of Count Humbert I of the House of Savoy.

Aosta Valley

The Aosta Valley (Italian: Valle d'Aosta (official) or Val d'Aosta (usual), French: Vallée d'Aoste (official) or Val d'Aoste (usual), Arpitan: Val d'Outa) is a mountainous semi-autonomous region in northwestern Italy. It is bordered by Rhône-Alpes, France to the west, Valais, Switzerland to the north and the region of Piedmont to the south and east.

With an area of 3,263 km2 (1,260 sq mi) and a population of about 126,933, it is the smallest, least populous, and least densely populated region of Italy. It is the only Italian region which has no provinces (the province of Aosta was dissolved in 1945). Provincial administrative functions are provided by the regional government. The region is divided into 74 comuni (communes).

Italian and French are both official, though the native population speaks also Valdôtain, a form of Franco-Provençal (Arpitan), as home language. In 2001, 96.01% of the Valdostan population reported knowing Italian, 75.41% French, 55.77% the Valdostan Franco-Provençal patois, and 50.53% all of them.
The regional capital is Aosta.
