What factors helped solidarity develop among American indianas?

Solidarity among American Indians developed due to shared experiences of colonization, displacement, and systemic oppression, which fostered a collective identity and mutual support. The rise of pan-Indian movements in the 20th century, such as the American Indian Movement (AIM), further strengthened unity by addressing common issues like treaty rights and cultural preservation. Additionally, the increasing visibility of Native rights in media and politics helped galvanize communities across diverse tribes to collaborate and advocate for their rights.
