awnser is The Second Industrial Revolution, also known as the “Technological Revolution,” was a phase of rapid industrialization in the final third of the nineteenth century and the beginning of the twentieth century. 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 invention of the Bessemer process in 1856, the Second Industrial Revolution is generally dated between 1870 and 1914 up to the start of World War I.
