The Madeira River is a major waterway in South America. It is estimated to be 1,450 km (900 mi) in length, while the Madeira-Mamoré is estimated near 3,250 km (2,020 mi) or 3,380 km (2,100 mi) in length depending on the measuring party and their methods. The Madeira is the biggest tributary of the Amazon, accounting for about 15% of the water in the basin. A map from Emanuel Bowen in 1747, held by the David Rumsey Map Collection, refers to the Madeira by the pre-colonial, indigenous name Cuyari.
The River of Cuyari, called by the Portuguese Madeira or the Wood River, is formed by two great rivers, which join near its mouth. It was by this River, that the Nation of Topinambes passed into the River Amazon.

They settled in localities along the Amazon River, such as Belém, Cametá, Santarém, Óbidos, Parintins, Itacoatiara and Manaus in Brazil, some venturing as far as Iquitos in Peru.

The Journalist Phelippe Daou Bridge is the fourth longest bridge in Brazil at 3,595 metres (11,795 ft) long, with a cable-stayed bridge section of 400 metres (1,300 ft), over the Rio Negro that links the city of Manaus with the small town of Iranduba in the state of Amazonas in Brazil. It spans the Rio Negro just before its confluence with the Amazon River, and is the only major bridge across the Amazon or any tributary in the Amazon basin. Its construction was marked by controversy over the potential effects of roadbuilding in the Amazon basin, which could lead to deforestation. A 2018 study found that the construction of this bridge did induce deforestation.

The history of Amazonas is the result of treaties, religious missions and a few indigenous rebellions in the Amazon territory. Initially, under the Treaty of Tordesillas, the site belonged to the Spanish Kingdom, but was later annexed by the Portuguese Crown. The state's international borders, undefined after Brazil's independence in 1822, were demarcated during the signing of the Treaty of Bogotá. Archaeological research suggests past occupations by Paleo-Indian hunter-gatherer groups, dated around 11,200 years before the present day.
