Isère (river) in the context of "Drac (river)"

Gratian (/ˈɡreɪʃiən/; Latin: Gratianus; 18 April 359 – 25 August 383) was emperor of the Western Roman Empire from 367 to 383. The eldest son of Valentinian I, Gratian was raised to the rank of Augustus as a child and inherited the West after his father's death in 375. He nominally shared the government with his infant half-brother Valentinian II, who was also acclaimed emperor in Pannonia on Valentinian's death. The East was ruled by his uncle Valens, who was later succeeded by Theodosius I.

Gratian subsequently led a campaign across the Rhine, attacked the Lentienses, and forced the tribe to surrender. That same year, the eastern emperor Valens was killed fighting the Goths at the Battle of Adrianople, which led to Gratian elevating Theodosius to replace him in 379. Gratian favoured Nicene Christianity over traditional Roman religion, issuing the Edict of Thessalonica, refusing the office of pontifex maximus, and removing the Altar of Victory from the Roman Senate's Curia Julia. The city of Cularo on the Isère river in Roman Gaul was renamed Gratianopolis after him, which later evolved to Grenoble. By 383 Gratian had become unpopular with his army, which abandoned him during a confrontation with the usurper Magnus Maximus near Lutetia (Paris). Gratian fled to Lugdunum and was later murdered.

Grenoble (/ɡrəˈnoʊbəl/ grə-NOH-bəl; French: [ɡʁənɔbl] ; Arpitan: Grenoblo or Grainóvol; Occitan: Graçanòbol or Grenòble) is the prefecture and largest city of the Isère department in the Auvergne-Rhône-Alpes region of southeastern France. It was the capital of the Dauphiné historical province and lies where the river Drac flows into the Isère at the foot of the French Alps.

The population of the commune of Grenoble was 158,198 as of 2019, while the population of the Grenoble metropolitan area (French: aire d'attraction de Grenoble or agglomération grenobloise) was 714,799 which makes it the largest metropolis in the Alps, ahead of Innsbruck and Bolzano. A significant European scientific centre, the city advertises itself as the "Capital of the Alps", due to its size and its proximity to the mountains. The many suburban communes that make up the rest of the metropolitan area include four with populations exceeding 20,000: Saint-Martin-d'Hères, Échirolles, Fontaine and Voiron.

Val-d'Isère (French pronunciation: [val dizɛʁ], literally Valley of Isère) is a commune of the Tarentaise Valley, in the Savoie department (Auvergne-Rhône-Alpes region) in southeastern France. It lies 5 km (3 mi) from the border with Italy. It is on the border of the Vanoise National Park created in 1963, with good transport links in and out of Lyon, Geneva and Chambéry.

During the Albertville 1992 Winter Olympics, the Face de Bellevarde was the site of the men's downhill race. Other alpine skiing events held during those games included men's giant slalom and alpine combined. Val d'Isère regularly hosts World Cup alpine events, usually for the men in early December, and hosted the World Championships in 2009. The ski area of Val d'Isère and Tignes forms the Espace Killy, named after the triple Olympic champion Jean-Claude Killy who grew up in Val d'Isère. There are two mountain huts (called “refuges” in French) owned by the Vanoise National Park on the territory of Val d'Isère: le Refuge du Prariond and le Refuge du Fond des Fours.

The French Prealps (French: Préalpes françaises [pʁealp fʁɑ̃sɛːz]) are a group of subalpine mountain ranges of medium elevation located immediately west of the French Alps. They roughly stretch from Lake Geneva southwest to the rivers Isère and Drôme; east to a line running from Chamonix, to Albertville, to Grenoble, to Gap, to Barcelonette; and south from Grasse to Vence.

In the northern subalpine regions, the various ranges are easily identifiable by geographical separations, such as the Voreppe Gorge between Vercors and Chartreuse, or Chambéry, which sits in a valley between the Bauges and Chartreuse ranges. In the southern subalpine regions, the ranges are generally disorganized and lack the wide, deep valleys that divide them in the north.

The Arly (French pronunciation: [aʁli]) is a 32.1 km long river in the departments of Savoie and Haute-Savoie, France. It is a tributary of the Isère, which it joins at Albertville.

Isère (US: /iːˈzɛər/ ee-ZAIR; French: [izɛʁ] ; Arpitan: Isera; Occitan: Isèra, Occitan pronunciation: [iˈsɛɾa]) is a landlocked department in the southeastern French region of Auvergne-Rhône-Alpes. Named after the river Isère, it had a population of 1,271,166 in 2019. Its prefecture is Grenoble. It borders Rhône to the northwest, Ain to the north, Savoie to the east, Hautes-Alpes to the south, Drôme and Ardèche to the southwest and Loire to the west.

The Tarentaise Valley (French: Vallée de la Tarentaise, pronounced [vale də la taʁɑ̃tɛz]; Arpitan: Tarentèsa; Italian: Tarantasia) is a valley of the Isère River in the heart of the French Alps, located in the Savoy region of France. The valley is named for the ancient town of Darantasia, the capital of the pre-Roman Centrones tribe.
