What is known as the American Revolution or the American Independence War, was much more than what its name suggests. What started in April 1775 as a revolt turned into a revolution within a year. With the intervention of France in July 1778, it became a transatlantic war, which in June 1779, when Spain entered the conflict, was transformed into a global war. This global conflict, fought in four continents as well as on the high seas, was rooted in the centuries-old confrontation between France, Spain, and Britain for the expansion and control of their empires. France and Spain shared a mutual interest in weakening the British. During the first stages of the conflict, both countries “secretly” supplied the American rebels, but as the war spread, their approaches differed. While France, with no territories in North America, allied with the recently proclaimed independent United States; Spain, with a vast American empire to protect, would only consider France as its official ally. Despite their different interests and tactics, Franco-Spanish joint operations in Europe, the Caribbean, and the South of North America, were decisive for the final British defeat.
