What is the time period that historians have labeled as the Second Industrial Revolution?​

The second Industrial Revolution is usually dated between 1870 and 1914, although a number of its char- acteristic events can be dated to the 1850s. It is, however, clear that the rapid rate of pathbreaking inventions (macroinventions) slowed down after 1825, and picked up steam again in the last third of the century.

The second Industrial Revolution lasted from the mid-19th century until the early 20th century and took place in Britain, continental Europe, North America, and Japan.
