The Point No Point Treaty was signed on January 26, 1855 at Point No Point, on the northern tip of the Kitsap Peninsula.[1] Governor of Washington Territory, Isaac Stevens, convened the treaty council on January 25, with the S'Klallam, the Chimakum, and the Skokomish tribes.[2][1] Under the terms of the treaty, the original inhabitants of northern Kitsap Peninsula and Olympic Peninsula were to cede ownership of their land in exchange for small reservations along Hood Canal and a payment of $60,000 from the federal government. The treaty required the natives to trade only with the United States, to free all their slaves, and it abjured them not to acquire any new slaves.
