Prince Henry the Navigator

Henry the Navigator, or Infante Dom Henrique, as he was known in his native Portugal, was born in 1394 and died in 1460. He was a prince of Portugal, but perhaps his most important title was that of governor of the Order of Christ, which was a successor to the Knights Templar. The Order of Christ controlled vast resources, which helped to fund Prince Henry's real passion: exploration. Prince Henry is rightly credited with inspiring the sense of adventure that led to the European era of exploration and discovery. Henry surrounded himself with expert cartographers and navigators. In addition, he was instrumental in the development of a new type of ship, the caravel. Without it, Columbus would have been hard pressed to sail to the Americas. In Age of Empires III: Definitive Edition, Henry is mostly agreeable, calm, and far-sighted. He favors economic expansion over military force and understands the value of trade. Henry is a generous and cooperative ally.
