How did Portugal, given its proximity, never become conquered by Spain?
That makes sense. Were there any specific events that helped Portugal maintain its independence from Spain?
One significant event was the Battle of Aljubarrota in 1385, where Portugal defeated an attempt by Spain to place a rival claimant on the Portuguese throne. Also, during the Spanish Empire's golden age in the 16th and 17th centuries, Portugal maintained its own overseas empire and helped establish a global trade network.
