  Rumors of undiscovered islands northwest of Hispaniola reached Spain by 1511, ushering King Ferdinand 's interest in forestalling further exploration. While the Portuguese were making huge gains in the Indian Ocean, the Spanish invested in exploring inland in search of gold and other valuable resources. The members of these expeditions, the " conquistadors ", were not soldiers in an army, but more like soldiers of fortune; they came from a variety of backgrounds including artisans, merchants, clergy, lawyers, lesser nobility and a few freed slaves. They usually supplied their own equipment or were extended credit to purchase it in exchange for a share in profits. They usually had no professional military training, but a number of them had previous experience on other expeditions.
  
  In the Americas, the Spanish encountered large indigenous empires and formed alliances with indigenous people through small expeditions. After establishing Spanish sovereignty and discovering wealth, the crown focused on implementing Spanish state and church institutions. A key element was the 'spiritual conquest' through Christian evangelization. The initial economy relied on tribute and forced labor under the encomienda system. The discovery of vast silver deposits transformed both the colonial economies of Mexico and Peru and Spain’s economy. With global trade networks and valuable American crops, Spain's economy strengthened, enhancing its status as a world power.
  
  During this time, pandemics of European disease such as smallpox decimated the indigenous populations.
  
  In 1512, to reward Juan Ponce de León for exploring Puerto Rico in 1508, king Ferdinand urged him to seek these new lands. He would become governor of discovered lands, but was to finance himself all exploration. With three ships and about 200 men, Léon set out from Puerto Rico in March 1513. In April they sighted land and named it La Florida —because it was Easter (Florida) season—believing it was an island, becoming credited as the first European to land in the continent. The arrival location has been disputed between St. Augustine, Ponce de León Inlet and Melbourne Beach. They headed south for further exploration and on April 8 encountered a current so strong that it pushed them backward: this was the first encounter with the Gulf Stream that would soon become the primary route for eastbound ships leaving the Spanish Indies bound for Europe. They explored down the coast reaching Biscayne Bay, Dry Tortugas and then sailing southwest in an attempt to circle Cuba to return, reaching Grand Bahama on July.
