Inventions of applicable electricity, steel, petroleum products, led to the second industrial revolution in 19th century, which meant the development of transport: railways, steam ships and development of maritime traffic. They expanded and improved the means of communication, the flow of information became much faster. New ways of producing, selling, and applying new products have been advertised. All this led to a greater supply of raw materials and the production of semi-finished products because the market demands were growing. In cities, there was an increasing demand for labor that was needed to make as much profits as possible. Workers did not benefit from that profit, on the contrary, they were in a more difficult position.
All of this resulted in the occurrence of popular democracy, trade unionism, and communism. Communism is, unfortunately, one of the most important effects.
All of this, it will show, will have a huge impact on the 20th century.
