The Mayangna (also known as Sumu or Sumo) are a people who live on the eastern coasts of Nicaragua and Honduras, an area commonly known as the Mosquito Coast.
Their preferred autonym is Mayangna, as the name "Sumo" is a derogatory name historically used by the Miskito people.
Their culture is closer to that of the indigenous peoples of Costa Rica, Panama, and Colombia than to the Mesoamerican cultures to the north.
The Mayangna inhabit much of the Mosquito Coast in the sixteenth century.
Since then, they have become more marginalized following the emergence of the Miskito as a regional power.
