Pierre Dugua de Mons (or Du Gua de Monts; c. 1558 – 1628) was a French merchant, explorer and colonizer.

The Devils Head Site, designated Site 97.10 by the Maine Archaeological Survey, is a prehistoric and historic archaeological site in Calais, Maine.
 Located on the banks of the St. Croix River, it is a shell midden site with evidence of multiple periods of human habitation, from the Middle Ceramic Period (c. 200-600 CE) to the Late Contact Period (mid-18th century) and beyond.
 With its location near Saint Croix Island, the site of an early French settlement in 1604, the site's finds may provide insight into early French-Native relations in the area.
 The site was listed on the National Register of Historic Places in 2006.
The governance of the French colony of Acadia has a long and tangled history.
 Founded in 1603 by Pierre Dugua, Sieur de Monts, the territory of Acadia (roughly, the present-day Canadian provinces of Nova Scotia, New Brunswick, and Prince Edward Island, and portions of the U. S. state of Maine) was hotly contested in the 17th century.
 It was claimed by English and Scottish interests, fought over by competing French governors, and subjected to raids and attacks from English colonists that sometimes resulted in years of occupation of some of its communities.
 Most of the non-French claims were given up under the 1667 Treaty of Breda, but the territory did not come completely under French control until three years later.
 From 1670 until 1710 the province remained in French hands, except for a brief period in the 1670s when Dutch attackers occupied several Acadian communities.
 In 1710 a British expedition including Royal Navy warships and colonial forces from New England captured Acadia's capital for good, and France ceded an ill-defined territory to Britain in the 1713 Treaty of Utrecht.
 Although France continued to claim those portions of present-day Maine and New Brunswick that constituted part Acadia, it had no formal government prior to the British conquest of New France in 1760.
 The first British governor of Nova Scotia was Samuel Vetch; he took command immediately after the 1710 capture.
