<P> 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 to 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 to produce steel , the Second Industrial Revolution is generally dated between 1870 and 1914 ( the start of World War I ) . </P>
