The Mughal War of Succession

Battle of Samugarh, 1658 — when Emperor Shah Jahan fell seriously ill, a fratricidal war erupted among his four sons for the throne, and the decisive engagement was fought near Samugarh, close to Agra, between the crown prince Dara Shikoh (Shah Jahan's favoured, liberal-minded eldest son) and the combined forces of his younger brothers Aurangzeb and Murad Baksh. Aurangzeb's superior generalship and disciplined artillery broke Dara's larger army; Dara fled westward, was later betrayed, captured, and executed on Aurangzeb's orders in 1659 on charges of apostasy. Aurangzeb then had the recovering Shah Jahan confined to Agra Fort for the remaining eight years of his life (cared for by his daughter Jahanara) and had himself crowned emperor, a title he held for the next 49 years — the longest reign of any Mughal ruler. The exam significance of Samugarh lies in what it represents structurally: the absence of a fixed law of succession in the Mughal Empire meant every transition of power risked becoming a war between brothers, and Samugarh is the bloodiest and most consequential instance of that pattern, since it installed the emperor whose policies would later provoke the Maratha, Rajput, and Sikh resistances of the following century.
