Dutch governor of Batavia, Jan Pieterszoon Coen, came up with an alternative plan. Coen founded Batavia, on the island of Java, as the Dutch East India Company's new capital in 1618. In 1621 he sailed to Banda with a fleet and proceeded to massacre almost the entire population of the islands, probably about fifteen thousand people. All their leaders were executed along with the rest, and only a few were left alive, enough to preserve the know-how necessary for mace and nutmeg production. After this genocide was complete, Coen then proceeded to create the political and economic structure necessary for his plan: a plantation society. The islands were divided into sixty-eight parcels, which were given to sixty-eight Dutchmen, mostly former and current employees of the Dutch East India Company. These new plantation owners were taught how to produce the spices by the few surviving Bandanese and could buy slaves from the East India Company to populate the now-empty islands and to produce spices, which would have to be sold at fixed prices back to the company.
