Why did Spain and France get involved in the American Revolution?
France hated the British with a passion, almost to a fault. They felt anything they could do to harm Britain would be good for them. The French financial assistance during the Revolution bankrupted them but they continued to feel it would be worth it as revenge for the seven years war. Spain’s help was very late in coming and negligible when it arrived. The main if not only reason for Spain to get involved was to regain Gibraltar and keep the areas of North America they controlled (Florida for one) from falling into British hands.
