Short Synopsis
The story of how nineteenth-century European rulers conspired with Mexican conservatives in an outlandish plan to contain the rising US colossus by establishing Old World empire on its doorstep.

Full Synopsis
The outbreak of the US Civil War provided an unexpected opportunity for political conservatives across continents. Mere decades after its founding, the United States had become a threat to European hegemony; instability in the United States could be exploited to lay a rival low. Meanwhile, Mexican antidemocrats needed a powerful backer to fend off the republicanism of Benito Juárez. When these two groups found each other, the Second Mexican Empire was born.

Raymond Jonas argues that the Second Mexican Empire, often dismissed as a historical sideshow, is critical to appreciating the globally destabilizing effect of growing US power in the nineteenth century. In 1862, at the behest of Mexican reactionaries and with the initial support of Spain and Britain, Napoleon III of France sent troops into Mexico and installed Austrian archduke Ferdinand Maximilian as an imperial ruler who could resist democracy in North America. But what was supposed to be an easy victory proved a disaster.

Based on research in five languages and in archives across the globe, Habsburgs on the Rio Grande fundamentally revises narratives of global history. Far more than a footnote, the Second Mexican Empire was at the center of world-historic great-power struggles—a point of inflection in a contest for supremacy that set the terms of twentieth-century rivalry.
