Rhine-Meuse-Scheldt delta in the context of "Port of Amsterdam"

The Port of Rotterdam is the largest seaport in Europe, and the world's largest seaport outside of Asia, located in and near the city of Rotterdam, in the province of South Holland in the Netherlands. From 1962 until 2004, it was the world's busiest port by annual cargo tonnage. It was overtaken first in 2004 by the port of Singapore, and since then by Shanghai and other very large Chinese seaports. In 2020, Rotterdam was the world's tenth-largest container port in terms of twenty-foot equivalent units (TEU) handled. In 2017, Rotterdam was also the world's tenth-largest cargo port in terms of annual cargo tonnage.

Covering 105 square kilometres (41 sq mi), the port of Rotterdam now stretches over a distance of 40 kilometres (25 mi). It consists of the city centre's historic harbour area, including Delfshaven; the Maashaven/Rijnhaven/Feijenoord complex; the harbours around Nieuw-Mathenesse; Waalhaven; Vondelingenplaat; Eemhaven; Botlek; Europoort, situated along the Calandkanaal, Nieuwe Waterweg and Scheur (the latter two being continuations of the Nieuwe Maas); and the reclaimed Maasvlakte area, which projects into the North Sea. The Port of Rotterdam is located in the middle of the Rhine-Meuse-Scheldt delta. Rotterdam has five port concessions (ports) within its boundaries—operated by separate companies under the overall authority of Rotterdam.

The Nieuwe Waterweg ("New Waterway") is a ship canal in the Netherlands from het Scheur (a branch of the Rhine-Meuse-Scheldt delta) west of the town of Maassluis to the North Sea at Hook of Holland: the Maasmond, where the Nieuwe Waterweg connects to the Maasgeul. It is the artificial mouth of the river Rhine.

The Chamavi were a Germanic people of Roman imperial times who lived north of the Roman border (Limes) in the Rhine river delta region, in what is now the Netherlands, and perhaps stretching into what is now Germany.

In the Roman records of the third and fourth century, when the tribes of this region began to be categorized as Franks or Saxons, the Chamavi were at different times listed as both, and sometimes distinguished from both. In the third century Chamavi and Frisians, apparently both considered Frankish peoples, settled in the Rhine delta during a period when the empire lost control of the region. After being defeated and ejected, they were once again mentioned as entering the area in the 4th century, but this time described as a Saxon people. After being once again defeated, they were forced to supply soldiers to the Roman military.
