D. Carlos I of Portugal was a world pioneer of oceanography, dedicating himself to the study of the Portuguese sea and leading 12 scientific campaigns that brought to the surface species never before seen in the depths of the Atlantic. His work enabled him to be the first to know and share the fauna of Portuguese waters, leaving a legacy scientifically recognized internationally.
The king was also passionate about various arts and distinct branches of science, but his greatest contribution was undoubtedly the in-depth study of the oceans. From the depths of the Atlantic, D. Carlos brought unknown marine creatures, which can today be admired at the Vasco da Gama Aquarium.
However, D. Carlos I is also remembered for his tragic end. On February 1, 1908, the king was assassinated in the middle of Terreiro do Paço, in Lisbon, by republicans and members of the Carbonária, in an episode that was marked in Portuguese history as the regicide.
