A story of espionage, shadow diplomacy, foreign scheming, and domestic backstabbing in the formative years of the American republic. Tyson Reeder's book traces early America's rocky beginnings, when foreign interference and political conflict threatened to undermine its aspirations and ideals, even its very existence. Spanning the period from the Revolution to the War of 1812, and focusing particularly on the presidency of James Madison, it reveals a nation adjusting to rancorous partisan politics, aggravated by the untested and imperfect new tools of governance and the growing power of media. Foreign powers, mainly Great Britain and Napoleonic France, exploited these conditions to advance their own agendas, interfering in U.S. elections to promote the outcome they favored. Dissent and disloyalty became dangerously interdigitated, nearly bringing the new republic to the brink of collapse. No figure was more in the center of it all than James Madison. As a leading delegate at the Constitutional Convention, Republican congressional leader, secretary of state, and president, Madison grappled with foreign meddling for over three decades. At the same time, he emerged as a political leader, feeding the very partisanship that bred foreign intrigues. As chief executive, he presided over the calamitous barrage of accusations and counteraccusations of foreign collusion that culminated in the War of 1812. Madison left a mixed but indelible legacy: as a fierce adversary of foreign interference, a fiery champion of political debate, and a partisan operative who facilitated the former by inflaming the latter. Forged in partisan conflict, the United States remains vulnerable to forces that test whether the constitutional system Madison was so central in implementing can withstand outside meddling while accommodating partisan conflict. Madison's successes and failures, along with his original vision of the Constitution and party politics, illuminate the ongoing struggle between domestic polarization and foreign interference.
