Established narratives portray Indigenous unity as emerging solely in response to the political agenda of the settler state. But unity has long shaped the modern Indigenous political movement. With Indigenous perspectives in the foreground, Assembling Unity explores the relationship between global political ideologies and pan-Indigenous politics in British Columbia through a detailed history of the Union of BC Indian Chiefs. Sarah Nickel demonstrates that the articulation of unity was heavily negotiated between UBCIC members, grassroots constituents, and Indigenous women's organizations. This incisive work unsettles dominant political narratives that cast Indigenous men as reactive and Indigenous women as apolitical.
