Which factor contributed to unrest in the Saskatchewan District concerning treaty obligations?

The choice that highlights the factor contributing to unrest in the Saskatchewan District concerning treaty obligations is the issue of supplies not being sent. This reflects a significant breach of the agreements made in treaties, which often included provisions for the delivery of essential goods and resources to Indigenous peoples. When these supplies were not delivered, it left many Indigenous communities struggling to meet their basic needs, leading to dissatisfaction and unrest.

This unrest stemmed from the growing realization that the promises made in historical treaties were not being honored by the government, causing deep frustration among the communities affected. These treaties were meant to create a partnership between Indigenous populations and the government, but failures in fulfillment, such as the non-delivery of supplies, caused a breakdown of trust and exacerbated tensions in the region. The impact of unfulfilled treaty obligations remains a critical discussion in the history of Canada and its relationship with Indigenous peoples.
