Flota system

The Spanish treasure fleet, or West Indies Fleet from Spanish Flota de Indias, also called silver fleet or plate fleet (from the Spanish plata meaning "silver"), was a convoy system adopted by the Spanish Empire from 1566 to 1790, linking Spain with its territories in America 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, luxuries, silver, gold, gems, pearls, spices, sugar, tobacco, silk, and other exotic goods from the Spanish Empire to the Spanish mainland. Passengers and goods such as textiles, books and tools were transported in the opposite direction. The West Indies fleet was the first permanent transatlantic trade route in history. Similarly, the Manila galleons were the first permanent trade route across the Pacific.

Spanish ships had brought goods from the New World since Christopher Columbus's first expedition of 1492. The Spanish government started a system of convoys in the 1560s in response to the sacking of Havana by French privateers. The main procedures were established after the recommendations of Pedro Menéndez de Avilés, an experienced admiral and personal adviser of King Philip II. The treasure fleets sailed along two sea lanes. The main one was the Caribbean Spanish West Indies fleet or Flota de Indias, which departed in two convoys from Seville, where the Casa de Contratación was based, bound for ports such as Veracruz, Portobelo and Cartagena before making a rendezvous at Havana in order to return together to Spain. A secondary route was that of the Manila Galleons or Galeón de Manila which linked the Philippines to Acapulco in Mexico across the Pacific Ocean. From Acapulco, the Asian goods were transhipped by mule train to Veracruz to be loaded onto the Caribbean treasure fleet for shipment to Spain. To better defend this trade, Pedro Menéndez de Avilés and Álvaro de Bazán designed the definitive model of the galleon in the 1550s.
