A revised edition of the classic monograph, The Ascendancy of the Congress in Uttar Pradesh investigates the social contradictions, class forces, and efforts at political organization and mobilization that lay behind the emergence of a powerful nationalist movement in Uttar Pradesh in the late 1920s and early 1930s. It also considers the concurrent emergence of Hindu-Muslim differences as a major factor affecting nationalist politics and the anti-colonial struggle in India. With a revised introduction and conclusion incorporating material from new research, and corresponding revisions throughout the text, the new edition extends the scope of the original work to cover the entire inter-war period, 1920-40.
