After Köppen, others took over the trading monopoly, though the economy suffered as a result of the Dano-Swedish war between Denmark-Norway and Sweden. During this period of the monopoly most Faroese goods (wool products, fish, meat) were taken to the Netherlands, where they were sold at pre-determined prices. The guidelines of the trading agreement, however, were often ignored or corrupted. This caused delays and shortages in the supply of Faroese goods and a reduction in quality. With the trading monopoly nearing collapse smuggling and piracy were rife.
