Guadeloupe is an island in the Windward Islands in the Eastern Caribbean that was first settled by French explorers in 1635. It was frequently occupied by the British during their various wars against France, in the 17th and 18th centuries, most notably by French royalists in 1791 following the revolution. The sugar plantations there struggled with the abolition of slavery in 1848. Guadeloupe used coins minted for all French New World colonies marked "Colonies Françaises", or counter marked coins until the first coins were minted for it in 1903 in 50 centimes and 1 Franc copper-nickel denominations. During WWII the islands remained under Vichy for most of the war. Today it remains, with its dependencies, an overseas department of France, and uses the Euro.
