Final answer:
The Treaty of Paris (1783) encouraged fair treatment of Loyalists and the return of confiscated property, but its suggestions were not consistently followed by the states.
Step-by-step explanation:
The Treaty of Paris (1783) addressed the treatment of Loyalists who supported Great Britain during the American Revolution by suggesting that the American government should treat these individuals fairly if they chose to remain in the United States after the war. It included terms that prompted individual states to refrain from persecuting Loyalists and encouraged the return of confiscated property. However, the adherence to these suggestions was inconsistent across the states, with many choosing not to return property or persecute Loyalists altogether, despite the recommendations of the Treaty and subsequent resolutions by the Confederation Congress in 1784.
