In the Koraput district of southern Odisha, the Mirgan weaving community has for generations produced Adivasi Pata—cotton saris, dupattas, and gamchas dyed a distinctive earthy maroon using the root and bark of the Aal tree (Indian madder, Morinda citrifolia), fixed with cow dung, wood ash, and castor oil in a process that involves no synthetic chemicals at any stage. The weaving itself is done on antique throw-shuttle pit looms, and the motifs, drawn from local flora, fauna, animistic beliefs, and everyday life, traditionally served as a visual code, with individual patterns marking the identity, gender, or rites of passage of the neighbouring tribal communities (the Dhurva, Muria, Kondh, and others) for whom the Mirgans wove. It became Odisha’s first GI-tagged textile in 2005, a recognition of nearly 2,000 years of documented sericulture and weaving history in the region.
