Research Aim: This study identifies various socio-economic discontents of the second industrial revolution through the Marx-Engels communist lens. It will analyse how the second industrial revolution brought undesirable socio-economic changes in Europe and the rest of the world. It will develop a socio-economic framework by using Karl Marx and Friedrich Engels’s critique of capitalism and social class theory to show the second industrial revolution divided the entire world into two classes. Moreover, it will show how imperialist powers used the second industrial revolution to change the world order.
