Sociology came to be established as an independent and a separate social science in the middle of the 19th century. Various factors paved the way for its emergence. Ian Robertson in his book "sociology" [pages: 11-12] has mentioned of three factors that hastened the process of the establishment of sociology as a separate science. They are,
- Industrial Revolution and Industrialisation.
- Inspiration from the Growth of Natural Sciences.
- Inspiration provided by the radically diverse societies and cultures of the colonial empires.
