Sociology is the study of society in a social system. In that social system, society always experiences change. There is no society that does not experience change, even at the smallest level, society (which consists of many individuals) will always change. These changes can be small changes to very large changes that can have a big influence on human activities or behavior. Changes can include narrow or broad aspects. Narrow aspects can include aspects of individual behavior and mindset. Broad aspects can be changes in the level of social structure that can later influence the development of society in the future. The study of social change, which is the core of studies in sociology, began around the 14th century. Ibn Khaldun, an Islamic thinker in the field of social science, first introduced the concept of social change. Khaldun stated that society historically moved from a nomadic society to a society (which lives) often referred to as an urban society.
Social change can be thought of as changes that occur within or encompass a social system. More precisely, there are differences between the state of a particular system over different periods of time. Therefore, the basic concept of social change involves three things: first, the study of differences; second, the study must be conducted at different times; and third, observations on the same social system. This means that in order to conduct a study of social change, we must see differences or changes in the conditions of the object that is the focus of the study. Second, the study of change must be viewed in a different time context, in other words, we must involve comparative studies in different time dimensions. Third, the object that is the focus of the comparative study must be the same object.
