Joel Roberts Poinsett's (1779-1851) brand of self-interested patriotism illuminates the paradoxes of the antebellum United States. He was a South Carolina investor and enslaver, a confidant of Andrew Jackson, and a secret agent in South America who fought surreptitiously in Chile's War for Independence. He was an ambitious Congressman and Secretary of War who oversaw the ignominy of the Trail of Tears and orchestrated America's longest and costliest war against Native Americans, yet also helped found the Smithsonian. In addition, he was a naturalist, after whom the poinsettia-which he appropriated while he was serving as the first US ambassador to Mexico-is now named.

As Lindsay Schakenbach Regele shows in Flowers, Guns, and Money, Poinsett personified a type of patriotism that emerged following the American Revolution, one in which statesmen served the nation by serving themselves, securing economic prosperity and military security while often prioritizing their own ambitions and financial interests. Whether waging war, opposing states' rights yet supporting slavery, or pushing for agricultural and infrastructural improvements in his native South Carolina, Poinsett consistently acted in his own self-interest. By examining the man and his actions, Schakenbach Regele reveals an America defined by opportunity and violence, freedom and slavery, and nationalism and self-interest.
