Under the Treaty of Paris of 1783, Michigan and Detroit were ceded to the United States. However England retained possession of this territory until 1796. England made use of the time to win the sympathy of the Canadian clergy. The propaganda paid off in 1795. Fifty Canadians on the American side declared their wish to remain English subjects. Some families even crossed to the British shore to remain under George III, an action that led to the foundation of Sandwich and Amherstburg. (Chronicles from the land of Cadillac).This treaty made the Detroit River an international border, the north shore becoming American. The south shore remained Canadian.
