A crisis of Iberian authority
Napoleon’s invasion of Iberia in 1808 created a crisis in Spanish royal authority. In the Americas, inhabitants argued over who could govern in the king’s name. Local juntas formed, and several regions challenged colonial officials around 1810. American-born elites sought political power, while Indigenous communities, enslaved people, and urban workers entered conflicts over land, taxes, and status. Independence comprised regional struggles with different social aims rather than one uniform programme.

Regional wars and different demands
Bolívar organized campaigns in northern South America and San Martín advanced from the south. Mexico experienced uprisings under Hidalgo and subsequent political changes. Armies recruited people, secured supplies, and crossed difficult terrain while warfare inflicted losses on civilians. By the 1820s, Spain’s mainland empire had largely ended. Brazil followed a different dynastic route out of Portuguese rule. Military, diplomatic, and territorial developments varied between the emerging states.

Republics and continuing disputes
Independence was followed by arguments about central government, local autonomy, the Church, and land. Gran Colombia broke apart, and constitutional experiments accompanied civil wars. Some colonial distinctions in legal status disappeared, while economic inequalities remained. Atlantic trade and international recognition created additional pressures. Separation altered the source of political authority and opened continuing struggles over participation in the state and the distribution of resources within it.
