Final answer:
The Idle No More Movement formed in response to the infringement on Indigenous lands, political recognition, and cultures due to colonialism and neocolonialism, and was part of continued efforts similar to those against the Dakota Access Pipeline and historical activism by the American Indian Movement.
Step-by-step explanation:
The Idle No More Movement of 2012-2013 emerged as a response to the struggles of Indigenous peoples for political recognition and the protection of their lands and cultures against the disenfranchising effects of colonialism and neocolonial relationships. This grassroots movement was part of a larger historical context where Indigenous groups engaged in social movements, including the struggle against the Dakota Access Pipeline by the Standing Rock Sioux and others in 2016, aiming to protect Native lands and sacred sites from the threats posed by the pipeline construction. The movement was also influenced by the history of the American Indian Movement (AIM), which, since the 1960s, has been actively engaged in public protests and actions to uphold tribal sovereignty and resist the federal government's oppressive policies.
