Answer:
The French Revolution.
Step-by-step explanation:
Auguste Comte was known as the "Father of Sociology"; he was influenced by the changes in society during the French Revolution. The class system in France changed dramatically during the French Revolution. These changes led Comte to study the patterns of society.
When Comte observed the need for new science to study such changes he named this study as 'sociology'. The term 'sociology' was derived from the Latin word 'socius' which means 'to be with others' or 'companion'.
