In the 1520s the Spanish had swept away the vast armies of the mighty Aztec Empire in a matter of months. In the Spice Islands of the Moluccas, the Dutch had recently begun to turn their cannons on the same rulers they had earlier traded with, slaughtering those islanders who rode out in canoes to greet them, burning down their cities and seizing their ports.
