The Rumsen (also known as Rumsien, San Carlos Costanoan, and Carmeleno) are one of eight groups of the Ohlone, an indigenous people of California. Their historical territory included coastal and inland areas within what is now Monterey County, California, including the Monterey Peninsula.[1]
Like other Ohlone, Rumsen no longer have federal recognition but continue to sustain their culture and community presence in central California.[2] This is despite the fact the Rumsen signed a treaty with the United States: the Treaty of Camp Belt, signed May 13, 1851. The treaty was then taken to Washington DC and hidden for 30 years while the US government attempted to learn if the land and water sources they "gave" to these tribes had gold in their streams or rivers.[citation needed]
