The Iberian Atlantic World encompasses diverse environs, peoples, cultures, religions, and societies scarred by the Atlantic slave trade and connected by a shared experience of conquest and colonization. This panel travels both spatially and temporally through this variegated world, from Spain’s earliest colonial projects in the Atlantic islands and the management of trade relationships in late colonial Florida to an interrogation of the development of Afro-Brazilian culture on the margins in the nineteenth century. Through discussions of diverging views and experiences of slavery, commerce, and economic and imperial policies, this panel re-centers marginalized histories of people and places, offering compelling and complementary narratives essential to understanding the complexity of the Atlantic World.
