he Prussian explorer Alexander von Humboldt visited the islands around 1802, and publicized guano’s value as a fertilizer throughout Europe. Seeing a lucrative business opportunity, Europeans and Americans fell on the area in a guano rush, and by the middle of the century several nations had enlisted the work of Chinese peasants in a Pacific labor system that has been compared with the slavery of the Atlantic world. Although the Chinese workers were technically free, many were debtors who had been tricked into labor contracts promising work in California. Once they reached the guano islands and realized they had been duped, there was no way off.
Alexander von Humboldt promoted guano as a valuable fertilizer, sparking a “guano rush” in the 19th century. Europeans and Americans exploited Chinese laborers, many tricked into contracts and trapped on islands, creating a system compared to slavery despite their technical freedom.
