The Second Industrial Revolution from 1870-1914 saw major technological innovations like steel, chemicals, electricity and petroleum that transformed industry. This led to increased industrial production and wages, creating a mass consumer society. However, most of the population remained part of the working class living in poor urban conditions. Reform efforts sought to improve workers' lives through laws, unions, and socialist political parties influenced by Karl Marx's ideas. The growth of cities also contributed to new social problems that governments attempted to address through public health initiatives. Overall, this period marked Europe's rise to global economic and political dominance fueled by industrialization, but also saw the emergence of social and political movements advocating for workers' and women's rights.
