percent of the half-million Loyalists remained in the United States and became American citizens. The others mostly went to Canada, and referred to themselves as the United Empire Loyalists. Merchants and men of affairs often went to Britain to reestablish their business connections. Rich southern Loyalists, taking their slaves with them, typically headed to plantations in the West Indies. The British also evacuated about 3,000 Black Loyalists, former slaves who had escaped from their American masters and joined the British; they went to Nova Scotia. Many found it inhospitable and went to Sierra Leone, a newly established British colony in Africa. The new nation gained control of nearly all the land east of the Mississippi and south of the St. Lawrence River and the Great Lakes. The British colonies of East and West Florida were given to Spain as its reward. The Native American tribes allied with Britain struggled in the aftermath; the British ignored them at the Peace conference, and most came under American control unless they moved to Canada or to Spanish territory. The British kept forts in the Northwest Territory (what is today the American Midwest, especially in Michigan and Wisconsin), where they supplied weapons to Indian tribes. 1783–1807: Role of Jay Treaty Trade resumed between the two nations when the war ended. The British allowed all exports to America but forbade some American food exports to its colonies in the West Indies. British exports reached £3.7 million, compared with imports of only £750,000. The imbalance caused a shortage of gold in the US. In 1785, John Adams became the first American plenipotentiary minister, to the Court of St James's. King George III received him graciously. In 1791, Great Britain sent its first diplomatic envoy, George Hammond, to the United States. When Great Britain and France went to war in 1793, relations between the United States and Great Britain also verged on war. Tensions were resolved when the Jay Treaty was approved in 1795. It established a decade of peace and prosperous trade relations. The historian Marshall Smelser argues that the treaty effectively postponed war with Britain, or at least postponed it until the United States was strong enough to handle it. According to American historian Samuel Flagg Bemis, the US had a list of outstanding issues: The British Army operated five forts in territory assigned to the US in the 1783 peace treaty in modern-day Michigan,
