Following the Second World War, the United States would become the leading 'neoliberal' proponent of international trade liberalization. Yet for nearly a century before, American foreign trade policy was dominated by extreme economic nationalism. What brought about this pronounced ideological, political, and economic about-face? How did it affect Anglo-American imperialism? What were the repercussions for the global capitalist order? In answering these questions, The 'Conspiracy' of Free Trade offers the first detailed account of the controversial Anglo-American struggle over empire and economic globalization in the mid- to late-nineteenth century. The book reinterprets Anglo-American imperialism through the global interplay between Victorian free-trade cosmopolitanism and economic nationalism, uncovering how imperial expansion and economic integration were mired in political and ideological conflict. Beginning in the 1840s, this conspiratorial struggle over political economy would rip apart the Republican Party, reshape the Democratic Party, and redirect Anglo-American imperial expansion for decades to come.

The forgotten history of the liberal radicals, socialist internationalists, feminists and Christians who envisioned free trade as the necessary prerequisite for anti-imperialism and peace Today, free trade is often associated with right-wing free marketeers. In Pax Economica, historian Marc-William Palen shows that free trade and globalization in fact have roots in nineteenth-century left-wing politics. In this counter-history of an idea, Palen explores how, beginning in the 1840s, left-wing globalists became the leaders of the peace and anti-imperialist movements of their age. By the early twentieth century, an unlikely alliance of liberal radicals, socialist internationalists, feminists and Christians envisioned free trade as essential for a prosperous and peaceful world order. Of course, this vision was at odds with the era’s strong predilections for nationalism, protectionism, geopolitical conflict and colonial expansion. Palen reveals how, for some of its most radical left-wing adherents, free trade represented a hard-nosed critique of imperialism, militarism and war. Palen shows that the anti-imperial component of free trade was a phenomenon that came to encompass the political left wing within the British, American, Spanish, German, Dutch, Belgian, Italian, Russian, French and Japanese empires. The left-wing vision of a “pax economica” evolved to include supranational regulation to maintain a peaceful free-trading system—which paved the way for a more liberal economic order after World War II and such institutions as the United Nations, the European Union and the World Trade Organization. Palen’s findings upend how we think about globalisation, free trade, anti-imperialism and peace. Rediscovering the left-wing history of globalism offers timely lessons for our own era of economic nationalism and geopolitical conflict.
