The formation of the All-India Progressive Writers’ Association (henceforth referred to as AIPWA) in 1936 was a “tumultuous episode” (Panikkar 2011, 14) in the cultural history of India, and this has been chronicled in a fairly exhaustive manner by a series of scholars, activists, and writers. The purpose of the book is not to recount the history of the Association with incremental iterations; the focus is more on its spatial spread, its horizontal affiliations, and its affective entanglements across various regions and registers of the entire Indian subcontinent, inviting the poets and the public in a relationship of progressive engagement. The emphasis is on the ‘all-India’—trans-regional—character of the Association, its exponential expansion across linguistic divides as a literary movement. The book aims to traverse the geography of South Asia to map how the progressive sentiment was nurtured and sustained by respective regional histories, traditions, and other local imperatives of culture. This enables us to draw a heterogeneous and, somewhat, uneven and differential character of progressive poetry in the Indian subcontinent. Progressive Indian literature is not a hegemonic monolith that subsumes the variety of voices of change and resistance, without its share of inner debates, quarrels, and distractions. Priyamvada Gopal also hints towards inner tussle within the progressive movement: “As with all organisations, leftist or otherwise, the history of the PWA is a history of struggle and contestation and not of the unilateral triumph of authoritarianism” (2005, “Introduction,” 4). The trajectories of regional progressive literatures across languages are not isomorphic as they do not parallel each other; some peak prior to the others, some continue to hold on to a progressive world-view, while some have diverged into other directions along the axes of caste, gender, nationalism, etc.
