Shelton was officially incorporated in 1890. The city was named after David Shelton, a delegate to the territorial legislature.[6] The land was previously called "Cota" and was inhabited and managed by theSquaxin Island Tribe, or "People of the Waters", who had inhabited the land for centuries before contact with white settlers. The land was ceded, along with 4,000 sq. miles of Indigenous land, on December 26, 1854, with the passage of theTreaty of Medicine Creek. After the passage of the treaty, David Shelton and his wife, Frances Shelton, each took a claim of land enabled by theDonation Land Claim Act totaling 640 acres in what would eventually be incorporated as Shelton.[7]
