Modern era

The modern era emerged from the profound changes caused by the
industrial revolution. This began in England in the late eighteenth
century where, in Birmingham, James Watt and Matthew Boulton
invented the steam engine, the first source of power independent of
human or animal exertion.
This was the first of many inventions and breakthroughs in
metals, chemicals, medicine and communications, and of the
discovery of new sources of power, including electricity, the
internal combustion engine and eventually nuclear fission. This
process continues with the advances in computers, satellite
communication and the Internet, which are affecting all aspects of
life.
These developments and the constant fall in the costs of
production led to unprecedented prosperity, and made those
countries in Europe and North America that pioneered the growth,
immensely powerful. The competition that this caused between them
led to a colonisation of much of the rest of the world by the late
nineteenth century. In the twentieth century it resulted in two
World Wars of appalling destructiveness.
Most of the European colonies gained their independence in the
1950s and 1960s, but the processes of closer international linkage
and globalisation have continued.
As more and more countries have industrialised and accumulated
wealth, and as agricultural and medical advances have resulted in
huge increases in population, the ill effects on the climate and
environment have become increasingly apparent. The success or
failure in controlling these will define the next era in human
history.
The late eighteenth, nineteenth and twentieth centuries are
represented in the British Museum collection by a wide range of
art, contemporary design, medals and other objects.
