What three things motivated prince Henry to pay for sailing expeditions?

Prince Henry of Portugal was motivated to fund sailing expeditions primarily by his desire to expand Portuguese trade routes, particularly for gold and spices. He aimed to spread Christianity by establishing contact with non-Christian lands. Additionally, he was driven by a fascination with exploration and the pursuit of scientific knowledge, seeking to map new territories and improve navigation techniques. These motivations collectively contributed to the Age of Discovery and Portugal's maritime dominance in the 15th century.
