What made it possible
- Napoleon's 1808 invasion of Spain removed the legitimate monarchy and left the American colonies governing themselves in the king's name, which set up both loyalty and autonomy as viable positions.
- The 1810-15 wars of independence in Venezuela and New Granada were fought largely by llanero cavalry and by British and Irish volunteers after the Napoleonic wars ended.
- San Martin's 1817 crossing of the Andes and the 1820-21 campaign in Peru divided Spanish forces between the highlands and the coast.
- The 1820 liberal revolution in Spain deprived the royalist commanders in America of reinforcements and of the political will to fight for an absolutist king.
Who acted
- Antonio Jose de Sucre
- Bolivar's commander at Ayacucho; later first president of Bolivia
- Jose de la Serna
- Last Spanish viceroy of Peru; wounded and captured at Ayacucho
- Simon Bolivar
- Liberated Venezuela, Colombia, Ecuador and Peru; not present at Ayacucho
- Jose de San Martin
- Crossed the Andes in 1817 to liberate Chile and Peru, then withdrew from politics in 1822
The battle, and why it was the last
Ayacucho was fought on a hillside in the Peruvian Andes between roughly 6,000 patriot troops under Sucre and about 9,000 royalists under Viceroy La Serna. The patriot army included Colombian, Peruvian, Chilean, Argentine and Venezuelan units, plus a British legion of some hundreds of veterans of the Napoleonic wars. The battle lasted about an hour; La Serna was wounded and captured, and his successor signed a capitulation that ended Spanish authority.
The surrender was general rather than local: the terms covered all royalist forces in Peru and provided that they would be permitted to withdraw to Spain. That is why the battle is treated as the end of the wars, even though isolated royalist garrisons held out at Callao until 1826 in the Andes and in Upper Peru.

The empire's map became the republics' map
The new states took their borders from the empire's administrative divisions, most of which had been redrawn in the eighteenth century for reasons of revenue and defence rather than culture. New Granada, Venezuela and Quito had been parts of different viceroyalties and captaincies-general, and the republics that emerged after 1830 corresponded closely to those units.
That inheritance is why so many Latin American border disputes are traceable to Bourbon administrative reforms. The boundaries were not designed to be international borders, and where the imperial records were ambiguous — as in the Amazon basin — the ambiguity outlived the empires by a century.
The fiscal inheritance
Independence removed the Spanish crown's monopoly on office but not the revenue structures. The new governments relied on customs duties and on the state monopolies of tobacco and liquor, and on internal tolls between provinces; income tax and direct taxation on land were politically impossible for most of the nineteenth century because the landowning class had led the independence movement.
The result was that the state's revenue depended on the prices of commodities it exported — silver, guano, nitrates, coffee, beef — and that a fall in the world price translated directly into political crisis. This pattern held from the 1820s until the 1930s and shaped the political economy of every republic in the region.

Consequence: short and long
Immediately
Spanish rule on the South American mainland ended, and the successor republics were organised around the imperial administrative units — viceroyalties, captaincies-general and audiencias — rather than around any prior national identity.
Over the long run
The new republics inherited the colonial revenue system's weaknesses: consumption taxes and state monopolies on tobacco and liquor, dependence on silver and later nitrates, and a state apparatus built to extract rather than to provide services. Political fragmentation followed the administrative map: Gran Colombia split in 1830 into Venezuela, Colombia and Ecuador; the United Provinces of Central America into five states by 1841. The economic result was a century in which Latin American states were price-takers in Atlantic markets and financed themselves through customs duties on exports they did not control.
The usual misconception
That independence was a mass nationalist movement. The patriot armies were small, multi-racial forces that included large numbers of black and mulatto soldiers and, after 1815, thousands of British veterans; the political leadership was largely creole elite. The majority of the population was not mobilised for the war and, in the Andean regions, was often recruited by both sides by force.
