In A Wide Net of Solidarity, Anne Garland Mahler traces the impact of the Anti-Imperialist League of the Americas (LADLA, Liga Antimperialista de las Américas) on racial justice and anti-extractive struggles from the early twentieth century to the present. Founded in 1925 in Mexico City by a group of multinational activists, LADLA brought together trade unions, agrarian organizations, and artist groups across fourteen chapters in the Americas, with highest activity in the Greater Caribbean and United States. Within two years, LADLA activists joined the League Against Imperialism, formed at the 1927 Brussels Congress, where they met with US Black activists and anticolonial leaders from Africa and Asia. Drawing on extensive archival research, Mahler uncovers LADLA’s role in fostering Black, Indigenous, and immigrant-led resistance movements while positioning these struggles within a broader hemispheric and global struggle against the racialized accumulation of capital. By unearthing LADLA’s multiracial analysis of capitalist exploitation as well as its emphasis on mutual solidarity across difference, Mahler shows us how the organization provides vital insight for social movements fighting racial and economic injustice today.
