UPSC aspirants should be familiar with key historical events such as the Independence Movement, Partition of India, and significant developments from post-independence India. Other important events include the freedom struggle led by leaders like Mahatma Gandhi and Jawaharlal Nehru, the Emergency (1975-1977), and major legislative reforms over the decades. Understanding these events helps candidates contextualize India’s political and social evolution, which is integral for general studies and essay writing in UPSC examinations.
