New France
In 1763, France had ceded the rest of New France, except the islands of Saint Pierre and Miquelon, to Great Britain and Spain at the Treaty of Paris, which ended the Seven Years' War (known as the French and Indian War in North America and especially the United States). Britain received Canada, Acadia, and the parts of French Louisiana which lay east of the Mississippi Riverexcept for the Île d'Orléans, which was granted to Spain, along with the territory to the westthe larger portion of Louisiana.
English overseas possessions in the Wars of the Three Kingdoms
In 1654, the New England Confederation voted to invade New Netherland to support the Commonwealth during the First Anglo-Dutch War. Massachusetts refused to join which severely undermined the Confederation. Cromwell sent naval reinforcements but the war ended while they were organizing their forces. This expedition was retooled to target Nova Scotia, the former Scottish colony that was ceded to French Acadia years earlier by Charles I. Cromwell claimed the Treaty of Suza and Treaty of Saint-Germain were invalid and that the French did not pay the purchase money. Nova Scotia was taken without significant resistance by Robert Sedgwick. This became an international incident since England and France were at peace but the French were busy fighting the Spanish and ceded the territory to England to secure the Commonwealth as an ally. England returned it to France in 1670 as according to the 1667 Treaty of Breda.
