Overview
The British Museum was created by Parliament in 1753 as a public collection of human history, art, books and natural knowledge, built first around the collections of the doctor and collector Sir Hans Sloane. It opened in Montagu House in 1759 and later filled Robert Smirke's great Greek Revival building. Its collections grew through excavation, purchase, gifts and Britain's worldwide trade and empire, leaving both an exceptional record of human cultures and serious arguments about how some objects were acquired and where they should belong.
What this place is
The museum holds about eight million objects covering roughly two million years of human history. Parliament founded it in 1753, and it opened in Montagu House in Bloomsbury in 1759. Entry was free but at first required an application and a timed ticket. The present main building was begun in 1823 to Robert Smirke's Greek Revival design and completed in 1852. Its public rooms, stores and study collections made one institution a museum, library and centre of learning on an unusually large scale.
People and events
Sir Hans Sloane's more than 80,000 collected objects, 40,000 books and manuscripts, and 32,000 coins and medals formed the core. The Cotton, Harley and Royal libraries added nationally important manuscripts. Later curators, collectors, excavators and colonial officers brought material from across the world. That growth created knowledge but also disputes: some objects were taken or transferred under unequal imperial conditions, and communities and governments continue to seek fuller accounts or return of particular holdings.
How it was used
Visitors came to compare the natural and human world, while scholars catalogued languages, coins, ancient societies, art and archaeology. The library's Round Reading Room, opened in 1857, became a major place of study. The natural-history collections moved to South Kensington in the nineteenth century and the British Library later became separate, leaving the Bloomsbury site chiefly concerned with human cultures. The museum still supports research, conservation, loans, teaching and free public visits.
What survives
Smirke's columned south front, quadrangle and much of the nineteenth-century museum survive. Sydney Smirke's circular Reading Room remains at the centre. In 2000 the former courtyard became the glass-roofed Great Court, designed by Foster and Partners, reconnecting routes through the building. The collections retain objects from ancient Egypt, Greece, Rome, Africa, Asia, Europe, the Americas and the Pacific, together with the written records needed to study their histories and ownership.
Why it mattered
The British Museum helped establish the idea that a national collection should be available to ordinary visitors rather than reserved for a ruler or private owner. Its objects have supported major work on ancient writing, art and societies, and the building changed Bloomsbury into a centre of public learning. It also matters because its history exposes how knowledge, wealth and power worked together: understanding the museum now requires both the stories told by its objects and honest study of how they reached London.
