On Monday 25 October, indigenous leaders from the Minga Indígena COP26 collective led activists and museum-goers through the many rooms of the British Museum. Panchita Calfin, an Indigenous elder from Mapuche nation in Chile, held an unauthorised healing ceremony inside the museum, to acknowledge centuries of injustice and oppression. This healing ceremony took place in the Americas section of the British Museum, surrounded by cabinets of stolen objects and symbols of colonial power. The rooms of the British Museum were marked with water from the highest mountains in the Andes. Leaders from Minga Indígena and Farhana Yamin, a former lead author of the IPCC, called for climate justice to be a unifying demand of COP26.
