MAP OF THE ROMAN REPUBLIC IN 133 BC

What was Portugal before it was Portugal? The sections below follow this land through every era covered by the Maps of History atlases: who ruled it, what it was called, and when control changed. Each line links to the dated map. Modern borders serve as an approximation, as each atlas says on the map itself.

Lusitania (mod. Portugal) · Ancient Rome

Viriathus, remembered as a shepherd who became a general, resisted Rome in Lusitania for a decade. Roman agents offered rewards to his killers, and he was assassinated in 139 BC. In one ancient account a consul tells them, “Rome does not pay traitors,” although payment had been promised. Augustus organized the province around Emerita Augusta (Mérida), founded in 25 BC for veterans; its theater, bridge and aqueduct still stand. After 409 Sueves took the north, while the south passed to Visigothic rule. The region’s Latin eventually developed into Portuguese.

Portugal — the western Reconquista · Crusades

Portugal emerged from the Reconquista as a new kingdom advancing south along the Atlantic. In 1147, English, Flemish and German crusaders on their way to the Holy Land stopped to help take Lisbon from the Muslims. The capture made Lisbon the Portuguese capital and supplied one of the few successes of the otherwise disastrous Second Crusade.

Portugal · Age of Revolutions

Portugal refused the Continental System and faced invasion in 1807. The royal court sailed to Brazil under British escort, making Portugal the only European monarchy to reign from a colony. Britain’s oldest ally also became the site of Wellington’s fortress at Torres Vedras. The country emerged from the age with a liberal constitution and civil wars, and without Brazil, which it lost in 1822.
