Comparative Historical Sociology is a field of sociology that focuses on how historical events shape societies. It is a comparative approach, meaning that it compares different societies to see how they have been shaped by different historical events.

Historical contingency is a key concept in Comparative Historical Sociology. It refers to the idea that historical events are not predetermined, but rather are contingent on a variety of factors, such as the actions of individuals, the structure of society, and the natural environment.

Path dependence is the idea that historical events have a lasting impact on a society. This is because historical events can create institutions and social structures that are difficult to change. For example, the Industrial Revolution created a new social class of factory workers, which had a lasting impact on the social and political structure of society.

Institutional isomorphism is the idea that societies are becoming more similar to each other. This is because societies are increasingly interconnected and interdependent. For example, the spread of global capitalism has led to the adoption of similar economic and political institutions in many different countries.

World-systems theory is a major theoretical approach in Comparative Historical Sociology. It argues that the world economy is a single system, and that the development of different countries is shaped by their position in the world economy. For example, countries that are at the center of the world economy are more likely to be developed than countries that are at the periphery.
