The Portuguese Rutter or Portuguese Nautical Mariners Notebooks, were at one point the most valued and sought-after papered works in western European history, which contained all the information needed to reach Asia's coastal exporting Trade Markets. Western Spain's historical links to the Arabian Caliphate in the 8th century had given the Spanish region it's sailing ship designs.
During the Dutch Revolt beginning around 1566, against Spanish Imperials and the Catholic Church, the Dutch became known as "Pirates of the sea", a religious label used to demonize and shutdown a new Dutch independent economy. The Dutch provinces and newly allied English took forceful measures in the 1500s to attempt at equalizing their wealth to Spain who were at first blocked off at The Strait of Gibraltar [The Spanish Blockade at Cadiz], policed by Spain and Allies.

Portugusse Rutter became "gold maps", nautical notebooks which contained trade routes around blockades, impeding ocean dangers, information on ports (including secret ports), intelligence of cultures with trade contacts, and personal notes or Captains Logs. Conflicts for Portuguese Rutter, either in bid or by force, occurred through the late 16th Century.
In 1598, five of the Dutch's best ships from Rotterdam Dutchland left shore to India and Southeast Asia trade networks, heavily armed, with the intent to establish a new Asian trade link, with additional orders to raid and fire upon Spanish or Arabian ships. What they found was that the Catholics were almost exclusive as shipping exporters in some Asian ports, but not all, and so began a trade War across the seas.
