The First World War was very hard on the residents of the canton. The cantonal authorities did little to prevent war time profiteering and prices for food and other necessities skyrocketed. At the same time, extensive unemployment and low wages led to starvation and poverty. Some of the major industries in Schwyz at the time were tourism and the textile cottage industry, both of which collapsed, so the canton suffered disproportionately. In 1918, Schwyzer troops were called up to join the Federal Army in suppressing striking workers in the canton of Uri, in Rapperswil and in the Zürich Oberland. When the Spanish flu broke out in the army camps many Schwyzer soldiers died. The poverty and death led to a polarization of politics and the Conservatives used the slogan of "flu-dead soldiers" until the mid-1930s.
