What additional books are needed beyond NCERTs for World History for UPSC?

NCERTs provide a basic storyline, but for the UPSC Mains, you need one supplementary resource for deeper analysis.
Norman Lowe’s Mastering Modern World History is the best choice for its clarity on complex events like the World Wars and the Cold War.
Alternatively, Arjun Dev’s History of the Modern World offers a more concise, UPSC-aligned narrative.
Focus strictly on the 18th century onwards, specifically the Industrial Revolution, Colonization, and Decolonization if you follow other resources.
