Lusitania was an ancient Roman province located in the Iberian Peninsula, corresponding roughly to modern-day Portugal and parts of western Spain. It was conquered by the Roman Republic in the 2nd century BC and became a significant part of the Roman Empire. Lusitania was known for its rich mineral resources and strategic importance. The inhabitants, the Lusitanians, were initially resistant to Roman rule. Think of Lusitania as a vital piece of the Roman Empire's western frontier.
