London is the capital and largest city of England and the United Kingdom. The city stands on the River Thames in the south-east of England, at the head of its 50-mile (80 km) estuary leading to the North Sea. London has been a major settlement for two millennia. Londinium was founded by the Romans. The City of London, London's ancient core and financial centre − an area of just 1.12 square miles (2.9 km2) and colloquially known as the Square Mile − retains boundaries that closely follow its medieval limits. The adjacent City of Westminster is an Inner London borough and has for centuries been the location of much of the national government. Thirty one additional boroughs north and south of the river also comprise modern London. London is governed by the mayor of London and the London Assembly.London is one of the world's most important global cities and has been called the world's most powerful, most desirable, most influential, most visited, most expensive, sustainable, most investment-friendly, and most-popular-for-work city.

Caral-Supe (also known as Caral and Norte Chico) was a complex pre-Columbian-era society that included as many as thirty major population centers in what is now the Caral region of north-central coastal Peru. The civilization flourished between the fourth and second millennia BC, with the formation of the first city generally dated to around 3500 BC, at Huaricanga, in the Fortaleza area. It is from 3100 BC onward that large-scale human settlement and communal construction become clearly apparent, which lasted until a period of decline around 1800 BC. Since the early twenty-first century, it has been established as the oldest-known civilization in the Americas.
This civilization flourished along three rivers, the Fortaleza, the Pativilca, and the Supe. These river valleys each have large clusters of sites. Farther south, there are several associated sites along the Huaura River. The alternative name, Caral-Supe, is derived from the city of Caral in the Supe Valley, a large and well-studied Caral-Supe site.
Complex society in Caral-Supe arose a millennium after Sumer in Mesopotamia, was contemporaneous with the Egyptian pyramids, and predated the Mesoamerican Olmec by nearly two millennia.
In archaeological nomenclature, Caral-Supe is a pre-ceramic culture of the pre-Columbian Late Archaic; it completely lacked ceramics and apparently had almost no visual art.
