The collection of Brazilian archaeology of the National Museum brought together a vast set of artifacts produced by the cultures that flourished in the Brazilian territory during the pre-colonial era, with more than 90,000 objects. It was considered the largest collection in its typology worldwide. Gradually assembled since the early 19th century, the collection started being systematically gathered since 1867 and has been continually expanded until the present day, through excavations, acquisitions and donations, also serving as basis for a large number of research projects conducted by the academics of the museum, the Federal University of Rio de Janeiro, and other institutions. It was composed of objects coming from all regions of Brazil, establishing a timeline spanning more than 10,000 years.
