Articles concluded between France and Portugal at Lyons, July 14, 1536.
As early as 1512 King Ferdinand of Spain complained that the King of Portugal sheltered in his ports French vessels lying in wait for the Spanish ships from the West Indies.1 A few years later the French corsairs became a terrible plague to both Spanish and Portuguese mariners, who in turn made reprisals on French shipping.2 When the Emperor and Francis I. renewed war in 1536, they both desired the friendship of Portugal, situated near the pathway of their ocean commerce.
