The European, or metropolitan, area of France extends from the Mediterranean Sea to the English Channel and the North Sea, and from the Rhine to the Atlantic Ocean. Overseas France include French Guiana on the South American continent and several island territories in the Atlantic, Pacific and Indian oceans. France spans and had a total population of almost 67 million people as of January 2017.

Other major urban centres include Marseille, Lyon, Lille, Nice, Toulouse and Bordeaux., The Cimbri were an ancient people, either Germanic or Celtic who, together with the Teutones and the Ambrones, fought the Roman Republic between 113 and 101 BC. The Cimbri were initially successful, particularly at the Battle of Arausio, in which a large Roman army was routed, after which they raided large areas in Gaul and Hispania. In 101 BC, during an attempted invasion of Italy, the Cimbri were decisively defeated by Gaius Marius, and their king, Boiorix, was killed. Some of the surviving captives are reported to have been among the rebelling Gladiators in the Third Servile War., Gaius Julius Caesar (13 July 100 BC  15 March 44 BC), known as Julius Caesar, was a Roman politician, general, and notable author of Latin prose.

According to the 2011 census, its population was 27,213,372. For statistic purposes, the Istituto Nazionale di Statistica (ISTAT) uses the term Northwest Italy and Northeast Italy for identifying two of the five statistical regions in its reporting. These same subdivisions are used to demarcate first level Nomenclature of Territorial Units for Statistics (NUTS) regions ("NUTS 1 regions") within the European Union, and the Italian constituencies for the European Parliament., Switzerland, officially the Swiss Confederation, is a federal republic in Europe. It consists of 26 cantons, and the city of Bern is the seat of the federal authorities.

Switzerland is a landlocked country geographically divided between the Alps, the Swiss Plateau and the Jura, spanning an area of .

It bordered on the west with the country of the Helvetii, on the east with Noricum, on the north with Vindelicia, on the west with Transalpine Gaul and on south with Venetia et Histria. It thus comprised the districts occupied in modern times by eastern and central Switzerland (containing the Upper Rhine and Lake Constance), southern Bavaria and the Upper Swabia, Vorarlberg, the greater part of Tirol, and part of Lombardy. Later Vindelicia (today south-eastern Wuerttemberg and south-western Bavaria) formed part of Raetia. The northern border of Raetia during the times of Augustus and Tiberius was the River Danube. Later the Limes Germanicus marked the northern boundary, stretching for 166 km north of the Danube. Raetia linked to Italy across the Alps over the Reschen Pass, by the Via Claudia Augusta. The Romansh people living in Southeast Switzerland are believed to be direct descendants of the Raetians. However, the exact lineage of the Romansh (or Romansch) people remains incomplete., Noricum is the Latin name for a Celtic kingdom, or federation of tribes, that included most of modern Austria and part of Slovenia. In the first century AD, it became a province of the Roman Empire. Its borders were the Danube to the north, "Raetia" and "Vindelicia" to the west, Pannonia to the east and southeast, and "Italia" ("Venetia et Histria") to the south.

It was probably through his counsel that Julian developed the skills of administration he displayed in Gaul . In 359 Constantius removed him from Gaul . When Julian became sole emperor , he raised Salutius to praetorian prefect of the Orient late in 361 . One of Salutius ' early tasks was to oversee the Chalcedon tribunal . He has sometimes been identified with `` Sallustius the Philosopher '' , author of the pagan theological pamphlet On the Gods and the World . Salutius accompanied his emperor on the Persian campaign , during which Julian was killed . As a sign of their great respect for him , the military command first nominated him to become their emperor , but Salutius refused the honor , pleading illness and old age , and the purple then fell to Jovian . After the return from Persia , Salutius continued in the office of praetorian prefect during the reign of Valentinian until he was replaced by Nebridius ., Germany, officially the Federal Republic of Germany, is a federal parliamentary republic in central-western Europe.

It is commonly preceded by the Bronze Age in Europe and Asia with exceptions and the Stone Age in Africa. Meteoric iron has been used by humans since at least 3200 BC, but ancient iron production did not become widespread until the ability to smelt iron ore, remove impurities and regulate the amount of carbon in the alloy were developed. The start of the Iron Age proper is considered by many to fall between around 1200 BC to 600 BC, depending on the region. In most parts of the world, its end is defined by the widespread adoption of writing, and therefore marks the transition from prehistory to history., Gaul (Latin: "Gallia") was a region of Western Europe during the Iron Age that was inhabited by Celtic tribes, encompassing present day France, Luxembourg, Belgium, most of Switzerland, Northern Italy, as well as the parts of the Netherlands, Central Italy and Germany on the west bank of the Rhine. It covered an area of 190,800 mi² or 494,169 km². According to the testimony of Julius Caesar, Gaul was divided into three parts: Gallia Celtica, Belgica and Aquitania.
Archaeologically, the Gauls were bearers of the La Tène culture, which extended across all of Gaul, as well as east to Raetia, Noricum, Pannonia and southwestern Germania during the 5th to 1st centuries BC.
During the 2nd and 1st centuries BC, Gaul fell under Roman rule: Gallia Cisalpina was conquered in 203 BC and Gallia Narbonensis in 123 BC. Gaul was invaded after 120 BC by the Cimbri and the Teutons, who were in turn defeated by the Romans by 103 BC. Julius Caesar finally subdued the remaining parts of Gaul in his campaigns of 58 to 51 BC., Belgium , officially the Kingdom of Belgium, is a sovereign state in Western Europe bordered by France, the Netherlands, Germany, Luxembourg, and the North Sea. It is a small, densely populated country which covers an area of and has a population of about 11 million people. Straddling the cultural boundary between Germanic and Latin Europe, Belgium is home to two main linguistic groups: the Dutch-speaking, mostly Flemish community, which constitutes about 59% of the population, and the French-speaking, mostly Walloon population, which comprises 41% of all Belgians. Additionally, there is a small group of German-speakers who live in the East Cantons located around the High Fens area, and bordering Germany., The La Tène culture was a European Iron Age culture named after the archaeological site of La Tène on the north side of Lake Neuchâtel in Switzerland, where thousands of objects had been deposited in the lake, as was discovered after the water level dropped in 1857. La Tène is the type site and the term archaeologists use for the later period of the culture and art of the ancient Celts, a term that is firmly entrenched in the popular understanding, but presents numerous problems for historians and archaeologists. The culture became very widespread, and presents a wide variety of local differences. It is often distinguished from earlier and neighbouring cultures mainly by the La Tène style of Celtic art, characterized by curving "swirly" decoration, especially of metalwork., Subject: salutius, Relation: date_of_death, Options: (A) 1 (B) 100 (C) 113 (D) 1200 (E) 13 (F) 16 (G) 166 (H) 169 (I) 1857 (J) 190 (K) 203 (L) 26 (M) 400 (N) 41 (O) 44 (P) 51 (Q) 58 (R) 59 (S) 600 (T) 61 (U) 67 (V) 8 (W) 800 (X) 82
