The Second Industrial Revolution occurred soon after the first, lasting from 1870-1914. This was also known as the Technological Revolution due to it being a period of massive technological growth. The First Industrial Revolution included the rise of many industries such as iron, textiles, coal, and railroads. During the Technological Revolution, many of these industries were expanded upon and advanced. Steel replaced iron as the primary building material. Innovations in electricity made public power possible. Petroleum was also discovered during this period as a fuel source. All of these new innovations in the fields of industry led to the invention of the internal combustion engine, which became used to power the newly invented automobiles and planes. Much of the world grew as a result of these inventions and innovations, including India.
