The area today known as Washington County was part of the ancestral lands of the Narragansett Indian Tribe. During the second half of the 17th Century, about a dozen English colonists from Newport and Massachusetts colonies moved to the area to establish farms; the larger of these were known as "Narragansett Planters." By the mid-18th century, there were 25 to 30 large plantations in the county, and their owners became very wealthy. The labor for these farms came from enslaved people; it is estimated that about 15% and 25% of Washington County’s population was enslaved. Washington County was created as Kings County in 1729 within the Colony of Rhode Island and Providence Plantations. It was renamed Washington County on October 29, 1781, in honor of George Washington. At the earliest stage of colonial settlement, the area was called "The Narragansett Country", named after the Naragansett tribe and its tributary tribe the Niantics, both of whom lived in the area. Early land purchases in the Narragansett Country were effected by settlers after the establishment of Indian trading posts at Fort Neck in Charlestown, and at Smith's Castle in Wickford. A series of conflicts involving the Manisseans on Block Island gave that island to the Massachusetts Bay Colony for a number of years, before being transferred to the Rhode Island Colony under Newport County, and then finally to Washington County in 1963. The borders of the Narragansett country were disputed for nearly 100 years among the colonies of Rhode Island, Connecticut, and Massachusetts. The Narragansetts had pledged their fealty to King Charles, and the area was known as "The King's Province" and was placed under the authority of Rhode Island "until the King's pleasure was further known". In 1664, a royal commission under Charles II stepped in to adjudicate these conflicting claims. The commission extinguished the claims of Massachusetts, and Rhode Island was granted jurisdiction until the commission finished processing Connecticut's appeals, which were not ended until 1726. Settlements of King's Province were named to reflect the English Restoration, in honor of King Charles II. Towns reflecting this history include the two Kingstowns and Charlestown, as well as the villages of Kingston and West Kingston. Washington County is also known in Rhode Island as "South County", though some definitions of South County include outside towns, such as East Greenwich in neighboring Kent County, and exclude towns within Washington County, such as New Shoreham.
