The British and the Americans signed the Treaty of Paris in 1783 to mark the end of the Revolutionary War. 

The treaty acknowledged American sovereignty and recognized United States boundaries. However, the British honored the treaty only to a certain extent. The promise to return former American slaves was not kept. Essentially, the British neglected to honor Article Seven of the 1783 treaty:

All prisoners on both sides shall be set at liberty, and his Brittanic Majesty shall with all convenient speed, and without causing any destruction, or carrying away any Negroes or other property of the American inhabitants, withdraw all his armies, garrisons, and fleets from the said United States, and from every post, place, and harbor within the same (from Article Seven of the 1783 treaty of Paris).

Instead, British commanders issued certificates of freedom to a number of former American slaves. General Sir Guy Carleton allowed American slaves and Loyalists from the colonies to board a ship for Nova Scotia. Meanwhile, thousands of slaves were encamped in London and left to fend for themselves; many starved to death or died from infectious diseases.

Additionally, the British also neglected to remove English troops from some American forts. Because the British neglected to abide by some provisions in the 1783 treaty, tensions between England and the colonies festered. The tensions foreshadowed future conflict, but war was prevented by the signing of John Jay's unpopular treaty in 1794. Please refer to the link below for more about the Jay treaty.
