The mid-nineteenth century saw the establishment in Java of one of the world's major sugar industries. Indeed, prior to the Great Depression of the 1930's, which reduced it to a shadow of its former opulance, the Java industry was second only to that of Cuba as a producer of cane sugar for the world's markets. It was essentially the creation of nineteenth-century Dutch colonialism. Sugar manufacture on a commercial scale had already been underway in Java a full two centuries earlier. However, the modern industry of large, centralized units of production and a massive ‘peasant’ workforce dated only from the inauguration of the state-sponsored Cultivation System by Governor-General Johannes van den Bosch in the 1830's. From then on, progress was rapid. Within less than a quarter century, some hundred or so sugar ‘factories’, solid stone places full of European machinery and Javanese ‘coolies’, had been established in the lowlands of Eastern and Central Java, and twenty-seven thousand hectares of peasant farmland requisitioned to provide them with cane. The whole enterprise dug deep into the innards of rural Java. As well as peasant land, the labour of the rural population was commandeered in unprecedented quantities. By the early 1860's, when sugar production under the auspices of the Cultivation System was reaching its peak, some 100,000 Javanese peasants were engaged in growing cane for the industry, and nearly that many again employed for between three and five months of the year, as cane-cutters, carters and factory hands during the manufacturing season or ‘Campaign’.
