Ems (river) in the context of "Emsland"

The County of Rietberg (German: Grafschaft Rietberg) was a state of the Holy Roman Empire, located in the present-day German state of North Rhine-Westphalia. It was situated on the upper Ems in Westphalia, between the Prince-Bishopric of Paderborn and the Prince-Bishopric of Münster. It existed as an independent territory from 1237 to 1807, when it was mediatised to the Kingdom of Westphalia.

The Frisii were an ancient tribe, who were neighbours of the Roman empire in the low-lying coastal region between the Rhine and the Ems rivers, in what what is now the northern Netherlands. They are not mentioned in Roman records after the third century, and archaeological records show that there was population decline, and frequent flooding caused by sea level rise. It is probable that many Frisii were among the early "Saxons" who settled in Britain. They are nevertheless also likely to be ancestors of the Frisians of today, whose material culture can be traced back to new settlements in the early Middle Ages.

Before the entry of the Romans into the area, settlers started to colonize the area in newly formed marshlands in the 6th or 5th centuries BC. As sea levels rose and flooding risks increased, the inhabitants learned to build their houses on village mounds or terps. The way of life and material culture of the Frisii hardly distinguished itself from the customs of the Chauci, east of the Ems.

The Chauci were an ancient Germanic tribe living in the low-lying region between the Rivers Ems and Elbe, on both sides of the Weser and ranging as far inland as the upper Weser. Along the coast they lived on artificial mounds called terpen, built high enough to remain dry during the highest tide. A dense population of Chauci lived further inland, and they are presumed to have lived in a manner similar to the lives of the other Germanic peoples of the region.

Their ultimate origins are not well understood. In the Germanic pre-Migration Period (i.e., before c. 300 AD) the Chauci and the related Frisians, Saxons, and Angles inhabited the Continental European coast from the Zuyder Zee to south Jutland. All of these peoples shared a common material culture, and so cannot be defined archaeologically. The Chauci originally centered on the Weser and Elbe, but in c. AD 58 they expanded to the River Ems by expelling the neighboring Ampsivarii, whereby they gained a border with the Frisians to the west. The Romans referred to the Chauci living between the Weser and Elbe as the 'Greater Chauci' and those living between the Ems and Weser as the 'Lesser Chauci'.

The Dortmund–Ems Canal is a 269-kilometre (167 mi) long canal in Germany between the inland port of the city of Dortmund (51°31′30″N 7°26′40″E / 51.52500°N 7.44444°E / 51.52500; 7.44444) and the seaport of Emden. The artificial southern part of the canal ends after 215 kilometres (134 mi) at Herbrum lock near Meppen. The route then takes the river Ems for 45 kilometres (28 mi) to Oldersum lock. From there, the canal continues along a second artificial segment of 9 kilometres (6 mi). This latter section was built because inland ships at the time of the construction of the canal were not built for the open sea, which they would have faced at the Dollart and the entry to the sea port of Emden. It is connected to the Ems-Jade Canal from Emden to Wilhelmshaven.

Emden (German pronunciation: [ˈɛmdn̩] ) is an independent town and seaport in Lower Saxony in the north-west of Germany and lies on the River Ems, close to the Netherlands border. It is the main town in the region of East Frisia and had a total population of 50,535 in 2022.
