Historical events are crucial for understanding the UPSC Civil Services syllabus as they provide context for various topics in Indian polity, history, and international relations. Aspirants can relate current affairs to historical precedents, enabling them to develop a comprehensive understanding of issues. This background facilitates deeper analysis and critical thinking, skills essential for success in the civil services. Moreover, knowledge of past events helps in answering questions more effectively in both the Prelims and Mains, allowing candidates to connect dots and present informed arguments.
