Treaty of Paris 1783: Britain Ceded Land East of Mississippi Except Florida

No, the statement is inaccurate. The Treaty of Paris (1783) ended the American Revolutionary War. Its territorial terms:

• Britain recognized U.S. independence with boundaries: Atlantic Ocean (east), Mississippi River (west), Great Lakes (north), Florida (south — 31°N parallel).
• Florida was returned to Spain (Britain had gained it in 1763; Spain entered war as French ally). Spain got both East and West Florida.
• New Orleans was never part of the British cession—it was French (ceded to Spain secretly in 1762, formally 1763). The U.S. acquired it in the Louisiana Purchase (1803) from France.

So: Britain gave the U.S. all land east of the Mississippi except Florida (which went to Spain). New Orleans was Spanish, then French, then American—never British in 1783.
