Madockawando (born in Maine c. 1630; died 1698) was a sachem of the Penobscot Indians, an adopted son of Assaminasqua, whom he succeeded. He led his people against the English settlers in New England during King William's War.
The Penobscot lands, lying east of Penobscot River, were a part of what the French called Acadia. The English returned this to France in 1667 by the Treaty of Breda, though the English claimed that the country between the Penobscot and the St. Croix River was included in the Duke of York's patent. The Indians were brought under French influence by Jean-Vincent d'Abbadie de Saint-Castin, known as Castin in the New England Chronicles, who was a trader who did much to gain influence with the Abenaki, Penobscot, and other local tribes. He settled among them, and married a daughter of Madockawando, a Penobscot chief.
When King Philip's confederacy rose against Plymouth Colony, the eastern Indians and the English settlers in Maine and New Hampshire became involved in war. The Penobscot people were the first among the Indian tribes to treat for peace, and offered to enter into an alliance with the English. Articles were drawn and subscribed at Boston on 6 November 1676, and the peace was ratified by Madockawando. The English, however, found a pretext for renewing hostilities. The Indians were successful, and destroyed all the English settlements in that part of Maine.
In 1678 a treaty was made at Casco, whereby the English were permitted to return to their farms on the condition of paying rent to the Penobscot. The peace was kept until the territorial dispute with France was brought to an issue in 1688 by Gov. Edmund Andros, who arrived among the Penobscot in a frigate. He plundered Castin's house and destroyed his fort. The Indian chiefs took up the quarrel, being abundantly supplied with arms by Castin, and attacked English settlements. This was one of the catalysts for King William's War, but the larger issue was competition between England and France for power in North America. Madockawando took a prominent part in the atrocities of this war.
