Defining a Nation is set at Simla, in the foothills of the Himalayas, where the British viceroy has invited leaders of various religious and political constituencies to work out the future of Britain’s largest colony. Will the British transfer power to the Indian National Congress, which claims to speak for all Indians? Or will a separate Muslim state—Pakistan—be carved out of India to be ruled by Muslims, as the Muslim League proposes? And what will happen to the vulnerable minorities—such as the Sikhs and untouchables—or the hundreds of princely states? As British authority wanes, tensions among Hindus, Muslims, and Sikhs smolder and increasingly flare into violent riots that threaten to ignite all India. Towering above it all is the frail but formidable figure of Gandhi, whom some revere as an apostle of nonviolence and others regard as a conniving Hindu politician. Students struggle to reconcile religious identity with nation building—perhaps the most intractable and important issue of the modern world. Texts include the literature of Hindu revival (Chatterjee, Tagore, and Tilak); the Koran and the literature of Islamic nationalism (Iqbal); and the writings of Ambedkar, Nehru, Jinnah, and Gandhi.Reacting to the Past is a series of historical role-playing games that explore important ideas by re-creating the contexts that shaped them. Students are assigned roles, informed by classic texts, set in particular moments of intellectual and social ferment.An award-winning active-learning pedagogy, Reacting to the Past improves speaking, writing, and leadership skills, promotes engagement with classic texts and history, and builds learning communities. Reacting can be used across the curriculum, from the first-year general education class to “capstone” experiences. A Reacting game can also function as the discussion component of lecture classes, or it can be enlisted for intersession courses, honors programs, and other specialized curricular purposes.
