Abstract
In recent years, scholars have explored the pivotal role Jewish merchants played in feeding and arming European armies from 1500 to 1800. Yet they have ignored the problems these merchants faced when they cast outside national borders to urban centres far from the battlefield, a multi-national mobilisation of resources known as the 'fiscal-military system'. This article uses a case-study of one Jewish merchant, Jacob Levi, from the port of Genoa to explore the essential brokerage role of ethnic-religious minorities in the early modern fiscal-military system. With knowhow built through his private businesses as well as a network of his co-religious, Levi became one of the most important suppliers of grain for the Bourbon army of northern Italy from 1702 to 1706. But foodstuffs did not transit alone; as Levi's records show, other war matériel accompanied grain, none more volatile than the at-least 17,000 barrels of gunpowder that Levi transited through the port in these years.
