Final answer:
Chief Theresa Spence's hunger strike was part of the 'Idle No More' movement that started in 2012, which focuses on Indigenous issues, including sovereignty and civil rights in Canada.
Step-by-step explanation:
Chief Theresa Spence's 43-day hunger strike was a significant part of the Idle No More campaign. This movement began in 2012 and focused on raising awareness for Indigenous issues, including sovereignty, environmental protection, and civil rights within Canada. Chief Spence's actions directed the national spotlight on the challenging living conditions in the Attawapiskat First Nations community and underscored the broader state of affairs for Indigenous peoples. In a broader historical context, the Idle No More campaign can be seen as part of a continuing series of Indigenous activism efforts, such as the Wounded Knee Occupation and the work of the American Indian Movement (AIM), both of which sought to draw attention to the struggles of Indigenous people and the mistreatment by federal and local agencies.
