The Second Industrial Revolution, also known as the Technological Revolution, was a phase of rapid industrialization in the final third of the 19th century and the beginning of the 20th. The First Industrial Revolution, which ended in the early-mid 1800s, was punctuated by a slowdown in macroinventions before the Second Industrial Revolution in 1870. Though a number of its characteristic events can be traced to earlier innovations in manufacturing, such as the establishment of a machine tool industry, the development of methods for manufacturing interchangeable parts and the invention of the Bessemer Process, the Second Industrial Revolution is generally dated between 1870 and 1914 up to the start of World War I.
Advancements in manufacturing and production technology enabled the widespread adoption of preexisting technological systems such as telegraph and railroad networks, gas and water supply, and sewage systems, which had earlier been concentrated to a few select cities. The enormous expansion of rail and telegraph lines after 1870 allowed unprecedented movement of people and ideas, which culminated in a new wave of globalization. In the same period new systems were introduced, most significantly electrical power and telephones. The Second Industrial Revolution continued into the 20th century with early factory electrification and the production line, and ended at the start of the First World War.
The Second Industrial Revolution was a period of rapid industrial development, primarily in Britain, Germany and the United States, but also in France, the Low Countries, Italy and Japan. It followed on from the First Industrial Revolution that began in Britain in the late 18th century that then spread throughout Western Europe and North America. It was characterized by the build out of railroads, large-scale iron and steel production, widespread use of machinery in manufacturing, greatly increased use of steam power, widespread use of the telegraph, use of petroleum and the beginning of electrification. It also was the period during which modern organizational methods for operating large scale businesses over vast areas came into use.
