As a Marxist republican, I find deep resonance in the historical bond between Karl Marx and Abraham Lincoln, a connection forged in the crucible of revolutionary struggle and mutual commitment to human emancipation. Though separated by an ocean, their correspondence during and after the U.S. Civil War revealed a shared vision: Lincoln, leading a bourgeois revolution that shattered the legal edifice of slavery, and Marx, recognizing in that struggle a blow against the global capitalist order’s reliance on racialized exploitation. From my perspective, Marx’s admiration for Lincoln was not mere political solidarity but a recognition that the fight against slavery was an essential step toward dismantling class domination. The International Workingmen’s Association’s letter to Lincoln in 1864, penned largely by Marx, affirmed that the fate of the American republic was intertwined with the worldwide struggle for justice. Today, as we continue confronting systemic racism, economic inequality, and the enduring legacy of racial capitalism, the symbolic alliance between Marx and Lincoln reminds me that the fight for equality must be both anti-racist and anti-capitalist—rooted in international solidarity and the unwavering belief that no person is free until all are free.
