Indigenous peoples and early habitation Archaeological evidence, including extensive shell middens, indicates continuous
Indigenous habitation of Mount Desert Island for at least 6,000 years. The
Wabanaki peoples, particularly the
Penobscot and
Passamaquoddy nations of the
Abenaki linguistic group, called the island
Pemetic, meaning "the sloping land". Archaeological evidence suggests Native Americans wintered on the coast to avoid harsh inland conditions and take advantage of marine resources, then moved inland during summers for
salmon runs and forest gathering. The Wabanaki constructed bark-covered conical dwellings and traveled in
birchbark canoes that European observers praised for their design and speed.
French colonial period (1604–1759) French exploration The first documented European encounter occurred on September 6, 1604, when
Pierre Dugua, Sieur de Mons led an exploring party from the
St. Croix Settlement. Sailing in a
patache with twelve sailors and two Indigenous guides while searching for the rumored city of
Norumbega,
Samuel de Champlain crossed
Frenchman Bay toward Otter Creek. During high tide, their vessel struck a ledge off what is now Otter Cliff, and while making repairs, two Indigenous people boarded as guides. Champlain recorded: "''Le sommet de la plus part d'icelles est desgarny d'arbres parceque ce ne sont que roches. Je l'ay nommée l'Isle des Monts-déserts''" ("Most of the summits are bare of trees because they are nothing but rocks. I have named it the Island of the Desert Mountains").
Saint-Sauveur Mission and the 1613 raid , site of the first French mission in North America In 1613, French
Jesuit missionaries established Saint-Sauveur Mission on present-day Fernald Point near
Somes Sound—the first French Catholic mission in North America. On July 2, 1613, Virginia colonial captain
Samuel Argall arrived aboard the
Treasurer and destroyed the mission. Three missionaries were killed, three wounded, and approximately twenty prisoners were taken to
Jamestown. Argall destroyed the buildings, replaced the Catholic cross with a Protestant one, then continued to eliminate French settlements at
Saint Croix Island and
Port-Royal.
Claude de La Tour quickly established a fur-trading post at nearby
Castine to maintain French influence.
Cadillac's land grant In 1688,
Antoine de la Mothe Cadillac received a royal grant for along the Maine coast, including all of Mount Desert Island. Despite ambitious plans for a feudal estate, Cadillac and his wife abandoned the project after a brief residence. Cadillac later founded
Detroit. The island's highest peak,
Cadillac Mountain (), bears his name and is among the first places in the United States to receive morning sunlight during fall and winter months.
Queen Anne's War raids During
Queen Anne's War, Mount Desert Island served as a staging ground for English raids against Acadian settlements. In 1704,
Benjamin Church gathered forces at the island before conducting raids on
Castine,
St. Stephen,
Grand-Pré, and other Acadian communities.
British colonial period (1759–1775) The
British conquest of Acadia in 1759 opened Maine coastal lands for British colonial settlement.
Sir Francis Bernard,
royal governor of Massachusetts, secured a land grant for Mount Desert Island and recruited settlers by offering free land. In 1760,
Abraham Somes and James Richardson became the island's first permanent European settlers, establishing homesteads at present-day Somesville.
Revolutionary period and early statehood (1775–1850) The
American Revolution disrupted Bernard's colonization plans. As a
Loyalist, he lost his land claims following American independence. Massachusetts granted the western half of Mount Desert Island to John Bernard (the governor's son, who supported the
Patriots) and the eastern half to Marie Thérèse de Grégoire (Cadillac's granddaughter). Both quickly sold to absentee landlords. By Maine's statehood in 1820, the island supported farming, lumbering, fishing, and shipbuilding. Settlers cleared hundreds of acres, producing everything from
schooners to household goods. Agriculture focused on wheat, rye, corn, and potatoes. By 1850, fishing fleets, fish-processing facilities, and shipyards dominated the landscape.
Granite quarrying became important, taking advantage of high-quality stone deposits near deep-water anchorages for shipping to major East Coast cities. ==Rusticators==
