Comparative politics, which involves the study of political systems and processes across countries, has undergone significant development in the 20th century. Some key developments in the field include:

• Influence of globalization: Comparative politics has also been shaped by the forces of globalization, with an increasing focus on the ways in which global economic, cultural, and political forces influence domestic politics in different countries.
• Increased focus on developing countries: In the 20th century, comparative politics also began to focus more on the study of developing countries, with an emphasis on understanding the political, economic, and social challenges facing these countries.
• Development of subfields: The field of comparative politics has also given rise to a number of subfields, including the study of political parties, elections, and democratization; political economy; and comparative public policy.
• Focus on democratization: In the latter half of the 20th century, comparative politics became increasingly focused on the study of democratization and the factors that contribute to the establishment and maintenance of democratic systems.
• Emergence as a discipline: Comparative politics as a distinct field of study emerged in the early 20th century, with the establishment of political science departments and the development of comparative methodologies.
