Henry the Navigator, the son of king John I of Portugal, improved his society in many ways. He is considered to be one of the pioneers of Age of Discovery, meaning that he paved the way for future European travels around the world, as well as trade. He was a famous politician and soldier as well, and he fought in the Battle of Ceuta (1415), which enabled <span>European forces to establish their first permanent position in North Africa.</span>
