There are a few major themes that come up over and over again during the course of classical sociological theory's development. All three classical theorists were writing at a time when sociology was a new and emerging discipline. This new discipline was called forth by momentous social changes taking place in European (and American) society during this time period. These changes were related to the rise of capitalism, industrialization, and new political representation for the majority of people (or, at least, a desire for such by many). Calls for socialism emerged as a response to recognition of new social divisions. Each of the three theorists you will read here weighed in on these historical changes, theorizing the contours and dynamics of this new "modern" society.
