Soissons (swasɔ̃) is a commune in the northern French department of Aisne, in the region of Hauts-de-France. Located on the river Aisne, about northeast of Paris, it is one of the most ancient towns of France, and is probably the ancient capital of the Suessiones. Soissons is also the see of an ancient Roman Catholic diocese, whose establishment dates from about 300, and it was the location of a number of church synods called "Council of Soissons". Soissons enters written history under its Celtic name, later borrowed into Latin, Noviodunum, meaning "new hillfort", which was the capital of the Suessiones. At Roman contact, it was a town of the Suessiones, mentioned by Julius Caesar (B. G. ii. 12). Caesar (B.C. 57), after leaving the Axona (modern Aisne), entered the territory of the Suessiones, and making one day's long march, reached Noviodunum, which was surrounded by a high wall and a broad ditch. The place surrendered to Caesar. From 457 to 486, under Aegidius and his son Syagrius, Noviodunum was the capital of the Kingdom of Soissons, until it fell to the Frankish king Clovis I in 486 after the Battle of Soissons. Part of the Frankish territory of Neustria, the Soissons region, and the Abbey of Saint-Médard, founded in the sixth century, played an important political part during the rule of the Merovingian dynasty (447–751). After the death of Clovis I in 511, Soissons was made the capital of one of the four kingdoms into which his states were divided. Eventually, the kingdom of Soissons disappeared in 613 when the Frankish lands were amalgamated under Chlothar II. The 744 Council of Soissons met at the instigation of Pepin the Short and Saint Boniface, the Pope's missionary to pagan Germany, secured the condemnation of the Frankish bishop Adalbert and the missionary Clement of Ireland. During the Hundred Years' War, French forces committed a notorious massacre of English archers stationed at the town's garrison, in which many of the French townsfolk were themselves raped and killed.
