When separatist revolts erupted in Spain's American colonies in the early 1800s, opinion in the United States was undecided as to what position to take. Proximity and America's own anti-colonial ethos favored sympathy with the rebel cause, yet U.S. strategic interests during the tumultuous Napoleonic Wars dictated a policy of neutrality. When representatives of the rebel provinces came to the U.S. seeking support, arms or recognition, and even launched armed assaults on Spanish territory and shipping from U.S. soil, American opinion split sharply. Should the untested rebel regimes be officially recognized or should the U.S. protect its crucial neutrality? As rebel agents and Spanish diplomat-spies vied behind the scenes for U.S. political and military assets, it became clear that the U.S. had inadvertently become involved in Spanish America's revolutionary struggle.

Menacing Tides shows how piracy disappeared from the Mediterranean through European security cooperation, enabling imperial expansion.

Europe was forged out of the ashes of the Napoleonic wars by means of a collective fight against revolutionary terror. The Allied Council created a culture of in- and exclusion, of people that were persecuted and those who were protected, using secret police, black lists, border controls and fortifications, and financed by European capital holders.

One of the most important themes in US history is the series of struggles that transformed the Southwest from a Spanish to an American possession: the Texas Revolution of 1836 and the Mexican–American War of 1845. But what if historians have been overlooking a key event that led to these wars—another war almost entirely unknown—that took place on what is now US soil and dramatically shaped the development of the American Southwest to this day? The true story of this war, presented in The Lost War for Texas: Mexican Rebels, American Burrites, and the Texas Revolution of 1811, is only now being revealed by never-before-published research, which will challenge paradigms and reshape much of what we know about United States, Texas, and even Mexican history. In the early 1800s, the impact of the Napoleonic Wars rippled across the Atlantic. Within weeks of the United States’s declaration of war on England in 1812, hundreds of western militia forces rallied to a flag and marched boldly to war—but not for the United States. They instead invaded the province of Texas to make common cause with Mexican rebels who had launched their struggle against the Spanish monarchy the year before. The resulting war changed the Southwest forever. Author James Aalan Bernsen places a spotlight on division and separatism at this pivotal moment of the “second revolution” of the United States. The Lost War for Texas, by revealing the forgotten war of 1811–1812 will profoundly change how we understand the birth of the American Southwest.

In 1822, the Mary departed Philadelphia and sailed in the direction of the Spanish colony of Puerto Rico. Like most vessels that navigated the Caribbean, the Mary brought together men who had served under a dozen different flags over the years. Unlike most crews, those aboard the Mary were in a different line of commerce: they exported revolution. In addition to rifles and pistols, the Mary transported a box filled with proclamations announcing the creation of the "Republic of Boricua." This imagined republic rested on one principle: equal rights for all, regardless of birthplace, race, or religion. The leaders of the expedition had never set foot in Puerto Rico. And they never would. When we think of the Age of Revolutions, George Washington, Robespierre, Toussaint Louverture, or Simón Bolívar might come to mind. But Rogue Revolutionaries recovers the interconnected stories of now-forgotten "foreigners of desperate fortune" who dreamt of overthrowing colonial monarchy and creating their own countries. They were not members of the political and economic elite; rather, they were ship captains, military veterans, and enslaved soldiers. As a history of ideas and geopolitics grounded in the narratives of extraordinary lives, Rogue Revolutionaries shows how these men of different nationalities and ethnicities claimed revolution as a universal right and reimagined notions of sovereignty, liberty, and decolonization. In the midst of wars and upheavals, the question of who had the legitimacy to launch a revolution and to start a new country was open to debate. Behind the growing power of nation-states, Mongey uncovers a lost world of radical cosmopolitanism grounded in the pursuit of material interests and personal prestige. In demonstrating that these would-be revolutionaries and their fleeting republics were critical to the creation of a new international order, Mongey reminds us of the importance of attending to failures, dead ends, and the unpredictable nature of history.

An exploration of the Spanish colonial reaction to the threat of Napoleonic subversion A Great Fear: Luís de Onís and the Shadow War against Napoleon in Spanish America, 1808–1812 explores why Spanish Americans did not take the opportunity to seize independence in this critical period when Spain was overrun by French armies and, arguably, in its weakest state. In the first years after his appointment as Spanish ambassador to the United States, Luís de Onís claimed the heavy responsibility of defending Spanish America from the wave of French spies, subversives, and soldiers whom he believed Napoleon was sending across the Atlantic to undermine the empire. As a leading representative of Spain’s loyalist government in the Americas, Onís played a central role in identifying, framing, and developing what soon became a coordinated response from the colonial bureaucracy to this perceived threat. This crusade had important short-term consequences for the empire. Since it paralleled the emergence of embryonic independence movements against Spanish rule, colonial officials immediately conflated these dangers and attributed anti-Spanish sentiment to foreign conspiracies. Little direct evidence of Napoleon’s efforts at subversion in Spanish America exists. However, on the basis of prodigious research, Hawkins asserts that the fear of French intervention mattered far more than the reality. Reinforced by detailed warnings from Ambassador Onís, who found the United States to be the staging ground for many of the French emissaries, colonial officials and their subjects became convinced that Napoleon posed a real threat. The official reaction to the threat of French intervention increasingly led Spanish authorities to view their subjects with suspicion, as potential enemies rather than allies in the struggle to preserve the empire. In the long term, this climate of fear eroded the legitimacy of the Spanish Crown among Spanish Americans, a process that contributed to the unraveling of the empire by the 1820s. This study draws on documents and official records from both sides of the Hispanic Atlantic, with extensive research conducted in Spain, Guatemala, Argentina, and the United States. Overall, it is a provocative interpretation of the repercussions of Napoleonic intrigue and espionage in the New World and a stellar examination of late Spanish colonialism in the Americas.

An American Language is a tour de force that revolutionizes our understanding of U.S. history. It reveals the origins of Spanish as a language binding residents of the Southwest to the politics and culture of an expanding nation in the 1840s. As the West increasingly integrated into the United States over the following century, struggles over power, identity, and citizenship transformed the place of the Spanish language in the nation. An American Language is a history that reimagines what it means to be an American—with profound implications for our own time.
