Did the Seneca Cayuga and the Onondaga?

The Seneca-Cayuga and the Onondaga are both part of the Haudenosaunee, or Iroquois Confederacy, which is a group of Native American tribes in the northeastern United States. The Seneca-Cayuga are often considered as one entity due to their historical association, while the Onondaga tribe serves as the central fire of the Confederacy, playing a key role in its governance and decision-making. Each tribe has its own distinct culture and history, but they share common traditions and political structures within the Confederacy.
