Abstract This article centers community archives as sources of history as well as sites of theory to map interconnected social and ecological struggles in the Niti Valley of the central Himalayas from the late nineteenth to the late twentieth centuries. Tolchha and Marchha communities have integrated different ecological belts over centuries through lifeways of trade, pastoralism, and herb gathering. Colonial and postcolonial policies threatened to sever these lifeways through militarized borders, timber extraction, and the demarcation of the exclusive boundaries of the Nanda Devi Biosphere Reserve. Yet tribal communities have fought to maintain ancestral relations with land by infringing upon colonial restrictions and defying dichotomies of nature and culture through the postcolonial Chipko and Jhapto Cheeno movements. Juxtaposing official archives with community archives from Lata Village, this article argues that leaders of people's movements have sought to reclaim authority over Himalayan history and resituate rural struggles within the framework of Indigenous spatial knowledges.
