Flags of South America
Twelve countries built on one real fault line: the Inca Empire — the largest pre-Columbian state in the Americas, centered on Peru — and other indigenous civilizations like the Muisca of Colombia and the Guaraní spread across Paraguay, conquered by Spain in the 1500s (Pizarro toppled the Inca in 1533) and organized into the Viceroyalties of Peru and New Granada / Río de la Plata. Portuguese Brazil ran on its own separate colonial track the entire time — still the only Portuguese-speaking country in the Americas.
Independence came as real war, not paperwork: Simón Bolívar and José de San Martín fought north and south through the 1810s–20s, and Bolívar's Gran Colombia briefly unified Venezuela, Colombia, Ecuador, and Panama before splitting apart within a decade. Brazil's own transition was comparatively peaceful — an 1822 declaration, then an Empire until 1889 before it became a republic. Guyana and Suriname sat outside the Iberian story entirely, held by Britain and the Netherlands and not independent until 1966 and 1975.
A real, traced map — actual coastlines and borders from the same geographic data used for a world atlas, not schematic shapes — covering all twelve countries at once. Drag the slider or press play; each snapshot simplifies a messier reality into the dominant power of the moment.
Borders here are data, not decoration. A line between two countries only draws solid when they were actually governed separately. When they weren't — Colombia, Venezuela, and Ecuador under one Gran Colombia government in the 1820s, say — the line dissolves and their names merge into whoever actually ruled them both. Colors blend between eras instead of jump-cutting.
One honest limitation: every region on this map is drawn to each country's modern outline. That works well for unions and splits (Gran Colombia's rise and fall shows up exactly as a real border appearing and disappearing) but it can't show a border moving within a country's own shape — so the War of the Pacific, where Chile annexed Bolivia's coastline outright, is explained in that era's story rather than drawn as a shape change.

The Inca Empire & indigenous nations
Real traced coastlines and borders (simplified from a world-atlas dataset). Panama/Central America and French Guiana shown faint for context only — not part of the twelve tracked countries.
Try: drag slowly from 1542 to 1776 and watch Spanish South America split from one enormous Viceroyalty of Peru into three separate viceroyalties, one real border at a time. Then jump to 1822 and watch two dissolves happen at once — Colombia, Venezuela, and Ecuador merging into Gran Colombia, and Uruguay merging into the Empire of Brazil as the annexed province of Cisplatina. At 1830, watch nearly every line on the map snap solid simultaneously as Gran Colombia splits and the wars end — the most crowded break on this whole map. Guyana and Suriname stay a separate story the entire time, never Spanish or Portuguese, dissolving into and out of just each other under Dutch rule before going their own ways as British and Dutch colonies.
About this hub
This hub now carries a full, map-driven treatment matching the atlas's other regional hubs (compare the Former Yugoslavia hub and the German Lands hub): a real traced map, built from the same geographic data used across the atlas, with an eight-point era slider running from the Inca Empire's peak through the Spanish and Portuguese conquests, the splitting Viceroyalties, Gran Colombia's rise and fall, the War of the Pacific, and Brazil's own empire-to-republic transition, to today's twelve independent nations.
Dedicated flag-timeline pages for all twelve countries — Brazil, Argentina, Chile, Peru, Colombia, Venezuela, Ecuador, Bolivia, Paraguay, Uruguay, Guyana, and Suriname — are linked above; the map above simplifies over five centuries of shifting sovereignty into eight snapshots, useful for orientation rather than a substitute for each country's own page.
