World peace lasted only a decade, for in 1793 a two decades of war between Britain and France and their allies broke out. As the leading neutral trading partner the United States did business with both sides. France resented it, and the Quasi-War of 1798–99 disrupted trade. Outraged at British impositions on American merchant ships, and sailors, the Jefferson and Madison administrations engaged in economic warfare with Britain 1807–1812, and then full-scale warfare 1812 to 1815.
