The Mayangna (/məˈjæŋnə/ mə-YANG-nə), also known as the Ulwa, are an Indigenous people who live on the eastern coasts of Nicaragua and Honduras, an area commonly known as the Mosquito Coast. They are sometimes referred to as the Sumu (or Sumo), 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 inhabited much of the Mosquito Coast in the 16th century. Since then, they have become more marginalized following the emergence of the Miskito as a regional power.
