Sociologists study all things that lead to the formation of relationships, society, the way people integrate and assimilate in societies, economics, shifts in societies, and culture.
In the 1830s, a man named Auguste Compte desired to establish a field of scientific study that was specific to human interactions. The early explorers led to an expansion of opportunities to meet and interact with new cultures. Exposure to other cultures also introduced speculation about other religions.
In the 18th and 19th centuries, the world began to shift as well. The rise of new technology and changes in the economy had an effect on science.
One significant discovery was the treatment of disease. Disease travels from person to person, and the discovery of disease meant that scientists and physicians needed to know how disease moved from one population to another and across far distances.
Industrialization led to a change in lifestyles and population shifts as people moved to work in factories. The shift in population evoked additional curiosity as scientists tried to understand urbanization, and its effect on people. Economics also changed with capitalism making growth. The subject of sociology was introduced into the college system in 1890 by Frank Blackmar. In 1995, Emile Durkheim set up a college department at the University of Bordeaux. Max Weber followed suit in Germany.
