In 1450, the Portuguese developed the carrack, a larger and more robust ship designed for long ocean voyages. This vessel combined square and lateen sails, enhancing its maneuverability and speed. The carrack played a crucial role in the Age of Exploration, enabling Portugal to establish trade routes and expand its maritime empire, significantly influencing global trade dynamics.

The Portuguese development of the carrack in 1450 enabled global explorations that were celebrated in epic poetry. Poets like Luís de Camões chronicled the adventures of explorers, intertwining themes of discovery with national pride, thus contributing to the narrative of Portugal's maritime legacy.
