Spanish treasure fleet
The Spanish treasure fleet, or West Indies Fleet (Spanish: Flota de Indias, also called silver fleet or plate fleet; from the Spanish: plata meaning "silver"), was a convoy system of sea routes organized by the Spanish Empire from 1566 to 1790, which linked Spain with its territories in the Americas across the Atlantic. The convoys were general purpose cargo fleets used for transporting a wide variety of items, including agricultural goods, lumber, various metal resources such as silver and gold, gems, pearls, spices, sugar, tobacco, silk, and other exotic goods from the overseas territories of the Spanish Empire to the Spanish mainland.
