Volume III covers the Iberian Empires and the important ethnic dimension of the Ibero-American independence movements, revealing the contrasting dynamics created by the Spanish imperial crisis at home and in the colonies. It bears out the experimental nature of political changes, the shared experiences and contrasts across different areas, and the connections to the revolutionary French Caribbean. The special nature of the emancipatory processes launched in the European metropoles of Spain and Portugal is explored, as are the connections between Spanish America and Brazil, as well as between Brazil and Portuguese Africa. It ends with an assessment of Brazil and how the survival of slavery is shown to have been essential to the new monarchy, although simultaneously, enslaved people began pressing their own demands, just like the indigenous population.
