In the history of exploration, Portuguese navigators were one of the most innovative sailers of their time. Portuguese explorers even had a navigation school established by Prince Henry in 1419, because exploration and the dominion of the seas was a priority to the kingdom of Portugal. Due to the knowledge of Portuguese sailors, they developed the technique called "Volta Do Mar" during the so-called Agre of Discovery. This technique perfectioned the knowledge of the North Atlantic Gyre, better known as the permanent cycle of the wind in the Atlantic Ocean. This made Portuguese sailors know more and depend on the wind to sail their ships.
